Step-by-step explanation:
Please mark me brainliest. I have never been marked brainliest before.
Let
x-------> the time in minutes
y-------> the temperature in Fahrenheit degrees
we know that
<u>the change in the y-values between two points is equal to</u>
Substitute the y-values of the point A and B in the formula
<u>the change in the x-values between two points is equal to</u>
Substitute the x-values of the point A and B in the formula
therefore
<u>the answer is</u>
The change in the y-value is 
and the change in the x-value is 
Answer:
The area of a rectangle with length of 5 and width of 5.
Step-by-step explanation:
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself.
area = lxw
A=5x5 (5 times itself)
A=25
therefore it is a perfect square
Answer:
This is a direct variation where the constant of variation is 5/9
Step-by-step explanation:
The equation for direct variation is y = kx
5x-9y =0
Lets try to get this equation in the above form
Add 9y to each side
5x-9y +9y = 9y
5x = 9y
Divide each side by 9
5/9 x = 9y/9
5/9x = y
This is in the form y = k x where k =5/9
