Answer:

3(-2-3x) = 9x-4

-6-9x = 9x-4

-6+6-9x = 9x-4+6

-9x = 9x+2

-9x-9x = 9x-9x+2

-18x = 2

-18x÷(-18) = 2÷(-18)

x = -(1/9)

Thank you

2. Write and solve an equation to find the value of x.<br> 3.8, 4.2, 5.3, x; mean 4.8

BabaBlast [244]

Answer:

5.9

Step-by-step explanation:

The mean means arithmetic average (some people just say average here).

The average of 4 numbers is the sum of those 4 numbers divided by the number of numbers which is 4 in this case.

So we have this formula:

$\frac{3.8+4.2+5.3+x}{4}=4.8$

Multiply both sides by 4:

$3.8+4.2+5.3+x=4(4.8)$

Simplify:

$13.3+x=19.2$

Subtract 13.3 on both sides:

$x=19.2-13.3$

Simplify:

$x=5.9$

What is f[g(7)] for the following functions?

Maksim231197 [3]

Answer:

Step-by-step explanation:

To evaluate f(g(7)), substitute x = 7 into g(x), then substitute the result into f(x)

g(7) = (2 × 7) - 5 = 14 - 5 = 9, then

f(9) = 3(9)² - 4 = 243 - 4 = 239 → C
