Answer:
So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.
f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given
f(5) = <u>3(5)</u> - 4
f(5) = <u>15 - 4</u>
f(5) = 11
f(2) = <u>3(2)</u> - 4
f(2) = <u>6 - 4</u>
f(2) = 2
f(1) = <u>3(1)</u> - 4
f(1) = <u>3 - 4</u>
f(1) = -1
f(10) = <u>3(10)</u> - 4
f(10) = <u>30 - 4</u>
f(10) = 26
f(-1) = <u>3(-1)</u> - 4
f(-1) = <u>-3 - 4</u>
f(-1) = -7

Answer: 28 hours
Step-by-step explanation:
1. Write original equation: 7.15x=3.40x+105
2. Combine like terms to isolate x: 3.75x=105
3. Divide both sides by same amount to find x: x=28
They would have to work 28 hours to earn the same amount of money.
Answer:
The rug is two feet too wide
Step-by-step explanation:
Well first, let's figure out the diameter of the rug to see if it will fit in the room. We know that the circumference of the circle is πd. So we can solve for d from there (d is the diameter).
c = πd
50.24 = πd
50.24/π = d
d = about 16 ft
Knowing this, we know that the rug would not fit in the room and if it was centered, it would have a foot of rug sticking out from each wall. Therefore, the rug is two feet too wide.
