Evaluate 4(x - 3) + 5x - x2 for x = 3.

x = 6

Step-by-step explanation:

4(x - 3) + 5x - x^2

Substitute x with 3

4(3 - 3) + 5(3) - 3^2

Solve via PMDAS so Parenthesis first

4(0) + 5(3) - 3^2

Multiply then the rest is Self-Explanatory

15 - 9

x = 6

Hope this helped!

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
