The solution for given linear inequalities is (-0.5,4.25) from the given graph.
What are linear inequalities?
Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.
The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.
e.g. y>x+2
Now,
As we know the solution for the lines which intersect at a certain point is that point or the coordinates of that point i.e. (-0.5,4.25).

A bookstore had 70 copies of a magazine. Yesterday, it sold 1/5 of them. Today, it sold 5/7 of what remained. How many copies does the bookstore have left?
Answers
Answer: 16
Step-by-step explanation:
1/5 x 70 = 14
70 - 14 = 56
5/7 x 56 = 40
56 - 40 = 16
Answer:
16
Step-by-step explanation:
Yesterday, the bookstore sold 1/5 of the 70 copies, which is 70 * 1/5 = 14 copies.
After selling 14 copies, the bookstore was left with 70 - 14 = 56 copies.
Today, the bookstore sold 5/7 of what remained, which is 5/7 * 56 = 40 copies.
So, the bookstore has 56 - 40 = 16 copies left.

The answer to the inequality system is y > 2 – x, y < -1
How to find the calculation?Step 1: Formulate each inequality as y = x + b.
(1) x + y > 2
(2) 2x – y > 1
(3) y > 2 - x Each side of the equation had x subtracted (1)
-y > 1 - 2x 2x were taken out of either side of 2.
(4) y < 2x – 1 -1 multiplied each side, then the inequality was turned around.
Graphing the functions as equalities in step two
(5) y = 2 – x
(6) y = 2x - 1
The borders of the inequalities will be formed by the lines. On one side of a line, the condition will be true, but not on the other (see the diagram below).
Step 3: Highlight the graphs' areas where the inequalities exist.
The graph of y > 2 - x is shown by the red line.
Shade the area above the line because y exceeds a value on the high side of the line (red).
The graph of y = 2x - 1 is shown by the blue line.
Shade the area below the line because y is less than a value on the line's low side (blue).
Any location where the colored regions overlap constitutes the solution set for both inequality problems (purple).
4. Check the outcome.
Input a point in the shaded region, such as (2, 2), and confirm that each inequality is true.
(1) x + y > 2 (2) 2x – y >1
2 + 2 > 2 2(2) – 2 > 1
4 > 2 4 – 2 > 1

The m∠EXD and m∠AXE are the supplementary angles.
The two angles will be linear pairs if the sum is 180° therefore, linear pair of 62° is 118°. The value of x in the figure is 113°
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
01)
Two angles will be linear pairs if their sum is 180°.
If the first angle is 62° then the second will be 180° - 62° = 118°
Hence "The two angles will be linear pairs if the sum is 180° therefore, linear pair of 62° is 118°".
02)
The angle x is in the same line with supplementary angle 67° so
x = 180 - 67 = 113°.
Hence "The value of x in the figure is 113°".

a six foot man standing 200 feet from a tower observes the angle of elevation to the top of the tower to be 67 degrees. how high is the tower?
Answers
So, the height of the tower is approximately 363.6 feet.
You can use trigonometry to solve this problem.
If we call the height of the tower "h" and the distance between the man and the base of the tower "d", then the angle of elevation is defined as the angle between the line of sight from the observer to the top of the tower and the horizontal line.
We can use the tangent function to relate the angle of elevation to the height and distance.
tan(67) = h/d
We know that the distance between the man and the tower is 200 feet. We can use this information to find the height of the tower.
h = d * tan(67)
h = 200 * tan(67)
The height of the tower is approximately 363.6 feet.

What is the right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, the right triangle that has two other right triangles inside it:
From the Pythagorean theorem:
Hyppotaneus ² = height ² + base²
from the Bigger triangle:
H = 14 + 4 = 18
b = y
h = x
Thus,
y² + z² = 18*18
y² + z² = 324.....(1)
from the triangle with a height of 14,
z² = x² + 14²
z² = x² + 196....(2)
From the triangle with the base of 4:
y² = x² + 16...(3)
For equations 2 and 3 substitute the value in equation 1
2x² + 212 = 324
2x² = 112
x² = 56; x = 2√14
Thus,
y² = 56 +16
y² = 74; y = √74
z² = 56 + 196
z² = 252; z = √252

We have to buy some chicken for dinner tonight. We found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than our usual neighborhood store, which sells it for $3.19 a pound.
Let's compare chicken costs: We need 3 pounds of chicken so, we would pay$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's see at how much it costs to travel in our car:For the neighbourhood store :
Distance = 2.3 mile
Multiply by 2 because we not only have to drive there, but also back home for the round trip: so, total distance = 2.3 miles × 2 = 4.6 miles
As car average is 19 miles per gallon
= 4.6 mile/ 19 miles per gallon
= 0.24 gallon < 13 gallons
Now, costs to travel to each store from the gas used. Cost of gas is $3.62/gallon,
total cost = 0.2421 gallons×$3.62 /gallons = $0.88
Similarly for far store : distance from home to store = 8.7 miles but take double of it we get, 8.7 miles × 2 = 17.4 miles
As car average is 19 miles per gallon
= 17.4 miles /19 miles per gallons
= 0.915 gallons < 13 gallons
The cost of gas for the respective trip = 0.915 gallons × $3.62 /gallons = $3.32
Now, let's add the gas and chicken costs together to get total worth
$19.14 + $3.32 = $22.46 to the far store
$20.34+ $0.88 = $21.22 to the near store
Hence, the worth in travelling far store is greater than neighbourhoid store.

Complete question:
You need to buy some chicken for dinner tonight. You found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than your usual neighborhood store, which sells it for $3.19 a pound. Is it worth the extra drive? First, determine what information you need to answer this question, then click here to display that info (along with other info).
How much chicken will you be buying? 3 pounds
How far apart are the two stores? My neighborhood store is 2.3 miles away, and takes about 8 minutes. The store across town is 8.7 miles away, and takes about 25 minutes.
How kind of mileage does your car get? It averages about 19 miles per gallon in the city.
How many gallons does your car hold? About 13 gallons
How much is gas? About $3.62/gallon right now.
Yes, it is worth the extra drive to the far store to get the chicken. The value of the two stores varied by around $1.24.
To make chicken for dinner tonight, we must purchase some. We discovered an advertisement indicating that the supermarket across town is selling it for $3.09 per pound, which is less expensive than our typical neighborhood grocery, which charges $3.19 per pound.
Compare the prices of chicken: We would pay for the 3 pounds of chicken that we require.
$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's look at the expense of driving in our car:
For the local retailer: = 2.3 miles away
Because we need to travel both ways, we must double the distance by two, making the total distance 2.3 miles x 2 = 4.6 miles.
Since the average automobile gets 19 mpg
19 miles per gallon/4.6 miles = 13 gallons x 0.24 gallons
Now, add the cost of gas used to drive to each store. Gas costs $3.62 per gallon.
Total cost = 0.2421 gallons at a cost of $0.88 per gallon.
The same goes for a far store:
the distance from home to the store is 8.7 miles, but if we double that by two, we get 17.4 miles.
Since the average automobile gets 19 mpg = 17.4 miles per gallon /19 miles per mile
13 gallons equals 0.915 gallons.
The gas price for the relevant journey is 0.915 gallons times $3.62 a gallon, or $3.32.
To determine the overall cost,
let's now combine the costs of the chicken and petrol.
$22.46 to the far store from $19.14 plus $3.32
$20.34 plus $0.88 equals $21.22 for the nearby retailer.
Therefore, a far store is more valuable than a nearby store. The difference is $1.24

In ΔRST, r = 79 inches, t = 70 inches and ∠T=58°. Find all possible values of ∠R, to the nearest 10th of a degree
Answers
In ΔRST, the measure of angle R is 73.1°
Let us assume that r represents the opposite side of ∠R, and 't' represents the opposite side of ∠T
i.e., r = side ST and t = side RS
We know that the law of sine for triangle states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.
i.e., for triangle ABC,
[tex]\frac{sin~A}{a} =\frac{sin~B}{b} =\frac{sin~C}{c}[/tex]
Using sine law for ΔRST,
[tex]\frac{sin~R}{r} = \frac{sin~S}{s} =\frac{sin~T}{t}[/tex]
Consider equation,
[tex]\frac{sin~R}{r} =\frac{sin~T}{t} \\\\\frac{sin~R}{79} = \frac{sin~(58)}{70}[/tex]
79 × 0.8481 = sin(R) × 70
sin(R) = 66.99 / 70
sin(R) = 0.9571
∠R = arcsin(0.9571)
∠R = 73.1°
Thus, measure of angle R = 73.1°
