The y value when f(x) = 3 is -12.

f(x) = -4x

To find the value of y when x equals 3, we need to replace all values of x with 3.

f(3) = -4(3)

f(3) = -12

Three years ago the average price of a movie ticket was $8.75 and now it is $11.00. What was the annual multiplier and the perce

Andrei [34K]

Given:
Price of tickets:
3 years ago - 8.75
now - 11

annual multiplier:

b³ = 11/8.75
b = ∛11/8.75
b = 1.079

The annual multiplier is 1.079.

1.079 * 100% = 107.9%

107.9% - 100% = 7.9%

The percentage increase is 7.9%

If one of them got there faster, who will it be?? 147 Miles keep that in mind ok. If they go on the Same route and Drive at Constant Speed. And Alan will start at 1:45 to 4:15. You will see the Difference of, 1:45 = 4:15 The 1 Has switched into the tens and the 4 Has Switched into The 100's. Alan Got there Fast. Margot Got there Faster. If you can Solve The Equation y=64x It will be 36y. 36 Miles speed. Well they need gas? we will find out later. Margot Got to City a To City B. so the Answer is. Margot Got there Fast Before Alan.

How do you find the exact value of sec θ if sin θ = -15/17 and 180 < θ < 270?

For $180^\circ$ , we expect to have $\cos\theta$ . Then if $\sin\theta=-\dfrac{15}{17}$ , we have
