Your answer is 500, review the image I created to understand how I got my answer.
Answer:
Dependent: Cost of the ride.
Independent : Number of rides.
Step-by-step explanation:
The independent variable is the variable what we change and the dependent variable is the variables which changes because of that changes.
Here the total cost of ride changes for any change in the number of rides.
Hence, the number of rides is the independent variable and the total cost of ride is the dependent variable
Answer:
The original area would be multiplied by the scale factor of 2² to get the new area.
Step-by-step explanation:
If you double the radius lets so lets do an example
(a=πr²) so
if x is the radius the area would be x²π
double the radius so 2x then the area would be
(2x)²π so 4x²π
4x²π/x²π= 4 so its 4 times greater or
D the last answer or The original area would be multiplied by the scale factor of 2² to get the new area.
Answer:
x =
± ![\frac{\sqrt{13} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B13%7D%20%7D%7B2%7D)
Step-by-step explanation:
Given
x² - 7x + 9 = 0 ( subtract 9 from both sides )
x² - 7x = - 9
Solve using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2( -
)x +
= - 9 +
(x -
)² =
( take the square root of both sides )
x -
= ±
= ±
( add
x =
±
= ![\frac{7+/-\sqrt{13} }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%2B%2F-%5Csqrt%7B13%7D%20%7D%7B2%7D)
Yes the relation is a function
