$\left \{ {{7x+6\:\:\:\:\:\:x$

$f(-1)$

Solve

$-7\cdot \:1+6x$ Swap the negative sign

$-7+6x$ Multiply the numbers

$-7+6x+7$ Add 7 to both sides

$6x$ Simplify

$\frac{6x}{6}$ Divide both sides by 6

$x$ Simplify

$-7\cdot \:1+12x$ Swap the negative sign

$-7+12x$ Multiply the numbers

$-7+12x+7$ Add 7 to both sides

$12x$ Simplify

$\frac{12x}{12}$ Divide both sides by 12

$x$ Simplify

slamgirl [31]

A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is $f(x) = -8(3^x)$ .

<u>Step-by-step explanation:</u>

Here we have to make A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis . Let's find out:

We have ,

A function that represents the exponential function f(x)= 3 to the power of x

Following is the equation for above statement :

⇒ $f(x) = 3^x$

A vertical stretch by a factor of 8

Following is the equation for above statement :

⇒ $f(x) = 8(3^x)$

A reflection across the x-axis

Following is the equation for above statement :

⇒ $f(x) = 8(3^x)(-1)$

⇒ $f(x) = -8(3^x)$

Therefore , A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is $f(x) = -8(3^x)$ .

Find the surface area of the cylinder use 3.14 for pi

elena55 [62]

Answer:

351.658 square in

Step-by-step explanation:

First find the circumference of the circle

C = 25.13

Find area of the circle

A = 50.27

Multiply the circumference by the height

25.13 × 10 = 251.3

Add 251.3 with 50.27 twice

251.13 + 50.27 + 50.27 ≈ 351.658

Therefore your answer is D) 351.658 square in

What is the price of the items Nakita bought?

timurjin [86]

Answer:

B $10.45

Step-by-step explanation:

Fist you find how much the 2 boxes of cracker cost

$3.50 * 2 = $7

Then subtract the amount of 2 crackers by the $0.80 coupon

$7 - $0.80 = $6.20

Then add that amount to the cost of a jar of peanut butter

$6.20 + $4.85 = $11.05

Then add that about for with the amount of a package of juice boxes

$11.05 + $2.40 = $13.45

Then subtract the total amount to the $3.00 coupon

$13.45 - $3.00 = $10.45

B $10.45 is your answer
