Answer:
y=mx+b is the form in which these equations are. B represents the y intercept and M is the slope
currently to find slope we need to get y alone on the left side of the equation for all the answers:
A.y-4=3(x-2) -----> y-4=3x-6 (i also distributed) ----> y=3x-2
B. y+4=-3(x+2)----> y+4=-3x-6 -------> y=-3x-10
C. y-2=-3(x-4) --------> y-2=-3x+12 ------> y=-3x+14
D. y-4= -3( x-2) --------> y-4= -3x+6 ---------> y=-3x+10
All of these equations except A have a slope of -3 so A is already out and to find which one is valid we need to plug in the point (2, 4) for each of the equations
B. 4=-3(2)-10 ------> 4=-6-10----> 4=-16- not valid
C. 4 =-3(2)+14 -----> 4=-6+14------>4=8 not valid
D. 4=-3(2)+10 ----->4=-6+10 ------> 4=4 - Valid
Only D is correct

In the figure, m<2 = 44. What is the measure of <1?
Answers
Answer:
m∠1 = 112°
Step-by-step explanation:
To solve for m∠1, we need to find the supplementary angle and subtract from 180°. We also know that m∠2 = 44° and the remaining two angles inside the triangle are the same because of the congruent sides, let's call each angle x.
Therefore m∠2 + x + x = 180; combine x's
m∠2 + 2x = 180; substitute m∠2 = 44°
44 + 2x = 180; subtract 44 from both sides
2x = 136; divide by 2
x = 68°
Therefore using the supplementary angle
x + m∠1 = 180 (because it is supplementary)
68 + m∠1 = 180; subtract 68 from both sides
m∠1 = 112°
Solve 3/5k-5=7/10k by eliminating the fraction. Explain how you determine what to multiply each term by and all the steps to solving the equation.
Answers

Answer:
k = -50
Step-by-step explanation:
The fraction denominators are 5 and 10. The least common multiple of those values is 10. This means we can eliminate fractions by multiplying both sides of the equation by 10:
6k -50 = 7k
Subtracting 6k from both sides of the equation leaves you with the solution:
-50 = k
On a map, 1 inch represents 100 feet. How many inches would
represent 350 feet? (Hint: answer will be a decimal) *
Answers
Answer:
3.5
Step-by-step explanation:
3.5 inches would represent 350 feet.
Inches and feetRelationship between inches and feet is that one inch is equal to [tex]\boldsymbol{100}[/tex] feets as per the map.
So,[tex]350[/tex] feet represent [tex]\frac{350}{100}=3.5[/tex] inches.
Therefore, [tex]\boldsymbol{3.5}[/tex] inches would represent [tex]350[/tex] feet in decimal.

Two rectangular boxes have the same volume. One box is a cube, and the other box has dimensions 8 ft by 4 ft by 16 ft. How many feet long is an edge of the cube?
Answers
Answer:
8 feet
Step-by-step explanation:
All you have to do is find the area of one box and find the root to find the cube edge, as it says they have the same volume.
Lets find the volume of the rectangular box.
8 x 4 x 16 =
32 x 16 =
512.
The volume of the cube is 512 feet cubed, but you are looking for the edge.
The edge cubed should be equal to 512 feet cubed.
So 512 cube root is 8, because 8 x 8 x 8 is 512.
8 feet.
Hope this helps!
Answer:
The answer to your question is 2744 ft³
Step-by-step explanation:
Data
length = 14 ft
width = 14 ft
height = 14 ft
- Volume of a Cube
Volume = length x width x height
-Substitution
Volume = 14 x 14 x 14
-Simplification
Volume = 2744 ft³
Conclusion
The volume of this cube is 2744 ft³

Step-by-step explanation:
A person has $28,000 invested in stock A and stock B. Stock A currently sells for $50 a share and stock B sells for $60 a share. If stock B triples in value and stock A goes up 50%, his stock will be worth $69,000. How many shares of each stock does he own?
Answers
Answer:
Number of stock A = 200
Number of stock B = 300
Step-by-step explanation:
Let :
Number of stock A shares = a
Number of stock B shares = b
Worth of stock A = 50 * a = 50a
Worth of stock B = 60 * b = 60b
50a + 60b = 28000 - - - (1)
Triple the value of stock B:
3 * 60 = 180
Value of stock A goes up by 50%
(100 + 50)% * 50 = 1.5 * 50 = 75
75a + 180b = 69000 - - - (2)
50a + 60b = 28000
75a + 180b = 69000
Multiply equation 1 by 3 and subtract
150a + 180b = 84000
75a + 180b = 69000
75a = 15000
a = 15000/75
a = 200
75(200) + 180b = 69000
15000 + 180b = 69000
180b = 69000 - 15000
180b = 54000
b = 300

Nicole has x dimes and y nickels. She has at least 15 coins worth a maximum of $1
combined. Solve this system of inequalities graphically and determine one possible
solution.
Answers
Answer:
Step-by-step explanation:
[tex]X + Y \geq 15\\\\10X + 5Y \leq 100[/tex]
we want to put it into terms of Y
[tex]y \geq 15 - x\\and\\5y \leq 100 - 10x\\y \leq 20 - 2x[/tex]
the graph is in the attached image. Any point in the shaded overlap region where x is greater than or equal to 0 (assuming you cannot have negative coins) works, e.g. (2, 14)
The solution of the inequalities is required.
One of the solutions is [tex](5,10)[/tex]
Number of dimes is [tex]x[/tex]
Number of nickels is [tex]y[/tex]
Minimum number of coins is 15.
So, [tex]x+y\geq 15[/tex]
Maximum total value of the coins is $1
So, [tex]0.1x+0.05\leq 1[/tex]
The equations are
[tex]x+y=15[/tex]
[tex]0.1x+0.05y=1[/tex]
Points of the first equation
[tex](0,15)[/tex] and [tex](15,0)[/tex]
Graph the points and draw a line through them.
Points of the second equation
[tex]x=0[/tex]
[tex]y=\dfrac{1}{0.05}=20[/tex]
[tex]y=0[/tex]
[tex]x=\dfrac{1}{0.1}=10[/tex]
[tex](0,20)[/tex] and [tex](10,0)[/tex]
Graph the points and draw a line through them.
The shaded regions can be determined by substituting the point in the equations.
One of the solutions is [tex](5,10)[/tex]
This means there are 5 dimes and 10 nickels.
[tex]5+10=15\geq 15[/tex]
[tex]0.1\times 5+0.05\times 10=1\leq 1[/tex]
Hence, one of the solutions is [tex](5,10)[/tex].

Write the linear equation in Slope-Intercept Form y = mx + b of the line that passes through the given points, then graph
the line.
Answers
Answer:
y = 3x + 7.
To graph the line mark off the 2 points and draw a line through them.
Step-by-step explanation:
The slope = (-2-7) / (-3-0)
= -9/-3
= 3.
The value of b is found using the point-slope form of a line:
y - y1 = m(x - x1)
using m = 3, (x1, y1) = (0, 7):
y - 7 = 3(x - 0)
y = 3x + 7.
