Use the Please Exuse My Dear Aunt Sally method. Add what's in the parentheses first. (30) times 3 (90) - 3 = 77 ! Wait actually you are correct! No mistakes here!
Answer:
horizontal stretch
Step-by-step explanation:
By looking at the attached image, you can easily determine what does what by comparing the functions to the graph.
Y=mx+b
m=slope
b=yint
y=16500-1500x
y=-1500x+16500
slope is -1500
yintercept is 16500
Answer:
D)x = 2y ^ 2
Step-by-step explanation:
y = 2x ^ 2
To find the inverse exchange x and y
x = 2 y^2
Then solve for y
Divide by 2
x/2 = 2y^2 /2
x/2 = y^2
Take the square root of each side
±sqrt(x/2) = y
