The ordered pair (6, 4) is not a solution to the inequality
The graph is given below
Option A is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Ordered pair = (6, 4)
This means,
(6, 4) = (x, y)
Now,
y < 3/4(x - 3)
Substitute (6, 4) = (x, y)
4 < 3/4(6 - 3)
4 < 3/4 x 3
4 < 4
This is not true.
From the graph,
(6, 4) is above the line.
Thus,
The graph is given below

Bicycles in the late 1800s looked very different than they do today.
60ft 9ft
a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.
Note that where the diameter of the bicycles are 60 inches and 9 inches respectively, the rotation of each tire after traveling 600 feet would be:
Small Tire (9in Diameter ) = 188.4 Rotations.
Big Tire (60 in Diameter) = 3.2 rotations
Note that the above were arrived at using the knowledge of Circumference.
What is the circumference of a circle?Note that the circumference in geometry is the perimeter of a circle or ellipse.
This is calculated using the formula:
C = 2πr
or
C = πD
Where C = Circumference
R = radius
D = Diameter which is 2r
π = 3.14
To arrive at how many rotations each tire did, we'd have to divide the distance traveled by the circumference of each tire.
For the Small Tire, the diameter is 9 feet.
Thus, the circumference of Small Tire = 3.14 * 9
= 28.26 feet
Thus, the rotations by the small tire is:
600/28.26
= 21.2314225053
[tex]\approx[/tex] 21.2feet
Applying the same process to the big tire, we have:
C = 3.14 * 60
C = 188.4
The rotations by the big tire =
600/188.4
= 3.1847133758
[tex]\approx[/tex] 3.2 feet.
Thus, the rotations by each tire over 600ft is given as:
Big Tire = 3.2

How are probabilities calculated?The probability of anything occurring is known as probability. To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur.There is a 50% chance that the outcome will be heads, thus 50 heads are to be expected.

the meaning of the rate of change in the context of this problem? Show all work.
The rate of change in this context refers to the change in the value of p, specifically between the peak and closing.This allows us to understand how much p changes on average between these two points in time.
What is the meaning of the rate of change in the context of this problem?It is a measure of how quickly or slowly the value of p is changing over time.
By calculating the average rate of change, we can understand the overall trend of the value of p and whether it is increasing or decreasing at a steady rate or if there are fluctuations.
This information can be useful for understanding the performance of a stock or investment, as well as predicting future trends.
Additionally, the rate of change can also help to identify any potential issues or opportunities within the market.
Overall, the rate of change provides a clear picture of the stock's performance over a certain period of time.
To calculate the average rate of change of p between peak and closing, we need to find the difference in p values (p(14) - p(8)) and divide that by the difference in time (14 - 8).
p(14) - p(8) = ? - ? = ?
(14 - 8) = ?
The average rate of change of p is ?/6.
The meaning of the rate of change in the context of this problem is the average change in the value of p per unit of time.
In this case, we are looking at the average change in p between the peak and closing, and expressing that change as a ratio of p(14) - p(8) to (14 - 8). This allows us to understand how much p changes on average between these two points in time.

alex earns a $35,000 salary in the first year of his career. each year, he gets a 3% percent raise. which expression gives the total amount alex has earned in his first n years of his career?
After n years Alex will earn salary which can be expressed as $(1 + 0.03)^n * 35,000.
The total amount Alex has earned in his first year of his career is $35,000.
In the second year of his career, he gets a 3% raise, which is an increase of 3/100 * $35,000 = $1,050.
So his salary for the second year is $35,000 + $1,050 = $36,050.
In the third year of his career, he again gets a 3% raise, which is 3/100 * $36,050 = $1,081.50
So his salary for the third year is $36,050 + $1,081.50 = $37,131.50
We can see that for each year, his salary is increasing by a fixed percentage of the previous year's salary.
This pattern can be represented by the expression:
(1 + 0.03)^n * 35,000
Where n is the number of years since the start of his career. This expression gives the total amount Alex has earned in his first n years of his career.

Formula to find the probability of an event:
"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
"Information available from the question"
Total number of students are,
n(S) = 10 + 16
n(S) = 26
Let event A: selecting first stick with a boy name
n(A) = 16
So, the probability of a boy is,
P(A) = n(A)/n(S)
P(A) = 16/26
P(A) = 8/13
if the first stick is not replaced, then n(S) would be,
26 - 1 = 25
Let event A: selecting first stick with a boy name
n(B) = 10
So, the probability of a boy is,
P(B) = n(B)/n(S)
P(B) = 10/25
P(B) = 2/5

Angela wants to learn how to rock climb. The Rocky Climbing gym has a special where 5 climbs cost $52.50.
Select the equation that represents the total cost, t, of c climbs. Assume the relationship is proportional.
Answer: t = 10.50c
Step-by-step explanation: The relationship between the number of climbs, c, and the total cost, t, is proportional. This means that the ratio of t to c is constant. One way to represent this relationship is through an equation of the form:
t = kc
where k is a constant of proportionality. In this case, we know that 5 climbs cost $52.50, so we can use this information to find the value of k:
52.50 = k(5)
k = 52.50/5 = 10.50
So the equation that represents the total cost, t, of c climbs is:
t = 10.50c
Where t is the total cost, c is the number of climbs and 10.50 is the constant of proportionality.

Step-by-step explanation:
First you have to graph your y-intercept (1) *which is the red dot in the graph I made for you*
Then you must use your slope (-2) to graph the rest
Since your slope is negative you have to go down from your y-intercept. In your case you are going down 2 units from your intercept. And since your slope is a whole number instead of a fraction you just go to the right 1 unit to make the coordinate (1,-1).
That is how you graph your equation.

12 ( x + 10 ) = 24
First we divide the two sides of the exercise by 12.
[tex]\boldsymbol{\sf{x+10=\dfrac{24}{12} }}[/tex]
We divide 24 by 12..
x + 10 = 2
Subtract 10 from both sides.
x = 2 - 10
Subtract 10 from 2 to get. Since the number 10 is greater than 2, the result will be negative.
x = -8
Answer:
[tex] \sf \: x = - 8[/tex]
Step-by-step explanation:
Given equation,
→ 12(x + 10) = 24
Now the value of x will be,
→ 12(x + 10) = 24
→ 12(x) + 12(10) = 24
→ 12x + 120 = 24
→ 12x = 24 - 120
→ 12x = -96
→ x = -96 ÷ 12
→ [ x = -8 ]
Hence, the value of x is -8.
