Answer:

Step-by-step explanation:

f(x) = 2ˣ + 1

-f(x) = -(2ˣ) − 1

First, let's find the y-intercept.

-f(0) = -(2⁰) − 1 = -2

Only C can be correct.

Marci bought 4 yards of ribbon for $6 how much should marci expect to pay for 10 yards of the ribbon?

Vinvika [58]

Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

$6 / 4 = 1.5$

Each yard costs $1.50, so let's multiply that by 10 $1.5 * 10 = 15$

Marci will pay $15 for 10 yards of the ribbon.

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?

Marina86 [1]

Answer:

The inverse of $2(x - 2)^2 = 8(7 + y)$ is $y=\sqrt{(4x+28)}+2$

Step-by-step explanation:

Given equation : $2(x - 2)^2 = 8(7 + y)$

$\Rightarrow \frac{2(x-2)^2}{8}=7+y\\\Rightarrow \frac{2(x-2)^2}{8}-7=y$

Replace x with y and y with x

So, $\Rightarrow \frac{2(y-2)^2}{8}-7=x\\\Rightarrow \frac{2(y-2)^2}{8}=x+7\\\Rightarrow 2(y-2)^2=8(x+7)\\\Rightarrow (y-2)^2=4(x+7)\\\Rightarrow (y-2)=\sqrt{4(x+7)}\\\Rightarrow y=\sqrt{4(x+7)}+2\\\Rightarrow y=\sqrt{4x+28)}+2$

So, Option C is correct

Hence The inverse of $2(x - 2)^2 = 8(7 + y)$ is $y=\sqrt{(4x+28)}+2$
