Answer:
13 dollars per hour ! ^^
Step-by-step explanation:
According to the proportional relationship shown by the graph, the rate of change is of 13 dollars per hour.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality, which is also the rate of change.
Considering the graph, the rate of change, in dollars per hour, is given by:
k = 65/5 = 26/2 = 13.

The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards
Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?
Answer: 28x + 15y = 131 and x + y = 7 where x is the number of Dress shirt and y is the number of T-shirt.
Step-by-step explanation:
We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.
We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal 131. Also, he bought 7 total shirts so x plus y has to equal 7.
28x + 15y = 131
x + y = 7

Answer:
x < -7 or x > -4
Step-by-step explanation:
If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?
PLEASE HELP!!
Answer:
3/2
Step-by-step explanation:
Given y = 2x + 5, let's rewrite the equation in terms of x;
y = 2x + 5 => Bring 5 to the other side
2x = y - 5 => Divide either side by 2
x = (y - 5)/2
If we want to take the inverse, simply swap the variable's positions...
We have y = (x - 5)/2
Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1
f^-1(8) = (8 - 5)/2 = 3/2
Solution: 3/2
