Answer: z=0

explanation:
7=-3z+7
move the -3z to the other side of the equation by adding -3z from both sides
7+3z=7
subtract 7 from both sides
3z=7
divide both sides by 3
z=0

you can check your answer by plugging in the answer into the equation ..
7=-3(0)+7
which gives you 7=7
so the answer is correct

If ƒ(x) = x − 4 and g(x) = 3x + 5, find (ƒ + g)(x).

Answer:

$(f+g)(x)=4x+1$

Step-by-step explanation:

We are given the two functions:

$f(x)=x-4\text{ and } g(x)=3x+5$

And we want to find:

$(f+g)(x)$

This is equivalent to:

$=f(x)+g(x)$

By substitution:

$=(x-4)+(3x+5)$

Rearranging yields:

$=(x+3x)+(-4+5)$

Combine like terms:

$=4x+1$

Hence:

$(f+g)(x)=4x+1$

10t = b - 4

12b+8t = $348

This is a system of equations. I’ll be solving through substitution.

In the first equation. solving for b (the easier variable to isolate) gives you:

b = 10t + 4

Substitute this into the second equation:

12(10t+4) +8t = 348

120t+48+8t = 348

128t = 300

t = 2.34375 —> round it to the nearest cent to get 2.34 dollars

b = 10t+4

b = 10(2.34)+4

b = 27.4 dollars
