Answer:
Option 2: y = ±sqrt(
)
Step-by-step explanation:
y = 7x^2 - 10
To find the inverse of a function, you must swap the y and x.
x = 7y^2 - 10
Now I will just simplify to have y by itself on the left hand side.
x + 10 = 7y^2
=y^2
sqrt()=±y
y = ±sqrt()
Since all three equations are equal, you take 15 x 20, which =300, once again because all of the equations are equal, take 300 and divide it by 5, that will give you your first question mark.{you should have gotten 60.} To find the second one, you are going to apply the same concept, Take 300 and divide it by 6, giving you your second question mark. {you should have gotten 50}...
P.S.: {hope I helped} :)
Answer:
i think
x=36 and y=13
Step-by-step explanation:
Answer:
200
Step-by-step explanation:
Assuming all of the pie chart sections are equal.
There are 5 equal sections so divide the 1000 spins by 5 and you get 200
