I need help please!!!
const2013 [10]

Part 1

<h3>Answer:   13</h3>

---------------------

Explanation:

We'll replace every copy of x with -3. Then use PEMDAS to simplify.

f(x) = -2x+7

f(-3) = -2(-3)+7

f(-3) = 6+7

f(-3) = 13

===========================================================

Part 2

<h3>Answer:  -11</h3>

---------------------

Explanation:

We work backwards in a sense compared to what part 1 did. Instead of finding f(x) based on x, we determine what x must be for a given f(x).

We'll replace f(x) with 29 and solve for x like so

f(x) = -2x+7

29 = -2x+7

-2x+7 = 29

-2x = 29-7

-2x = 22

x = 22/(-2)

x = -11

Note how if you replaced x with -11, we'd get,

f(x) = -2x+7

f(-11) = -2(-11)+7

f(-11) = 22+7

f(-11) = 29

which helps confirm we have the correct answer.

Chanasia has 8.75 gallons of paint. She wants to use 2 5 of the paint to paint her living room. How many gallons of paint will C
GaryK [48]

Answer: 3.5 gallons

Step-by-step explanation:

From the question, we are told that Chanasia has 8.75 gallons of paint and that she wants to use 2/5 of the paint to paint her living room.

The gallons of paint that Chanasia will use be gotten by multiplying 2/5 by 8.75 gallons. This will be:

= 2/5 × 8.75 gallons

= 0.4 × 8.75 gallons

= 3.5 gallons.

This means that Chanasia will use 3.5 gallons to paint her living room
