Answer:

f(9) = 61

Step-by-step explanation:

You know f(x) = 8x - 11. So, to find f(9), you have to replace x with 9 on the other side.

f(9) = 8(9) - 11

You can solve this.

f(9) = 72 - 11

f(9) = 61

Answer:

152°

Step-by-step explanation:

If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.

The measure of each angle in the other congruent pair is 152°.

Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence correspo

Fantom [35]

Answer:

$y = 5(6) {}^{x}$

Step-by-step explanation:

A exponential function is represented by

$y = ab {}^{x}$

where a is the vertical stretch and b is the base and x is the nth

power of x

Since the first number corresponds with zero, that means our y intercept is the first number.

This means when x=0 , y=5 so let find the value of 5.

$5 = ab {}^{0}$

b to the 0th power equal 1 so

$5 = a \times 1$

$a = 5$

Our equation is for now

$y = 5b {}^{x}$

Now let plug in 1,30

$30 = 5b {}^{1}$

Divide 5 by both sides

$6 = b {}^{1}$

Anything to the 1st power is itself so b equal 6.

So our equation is

$y = 5(6) {}^{x}$

If 5 slices of pizza cost $5:50 how much does

kupik [55]

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

$y = (\frac{5.50}{5}) * x$

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

$y = (\frac{5.50}{5}) * 2\\y = 2.2$

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

$y = (\frac{5.50}{5}) * 10\\y = 11$

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

$y = (\frac{5.50}{5}) * \frac{1}{2}\\y = 0.55$

Answer:

half a slice = 0.55 $
