What is the value of X

Mathematics
1 answer:
Alexus [3.1K]3 years ago
6 0

Answer:

30

Step-by-step explanation:

Use part/whole proportions. 10/25 (15 + 10) = 12/x. Multiply 12 times 25 (300) = 10x (10 times x). 300 = 10x, isolate x by dividing both sides by 10 and you get 30 = x.

Help with this question??
Reika [66]

Answer:

3

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 0, 2 ] and from the graph

f(b) = f(2) = 0

f(a) = f(0) = - 6, hence

average rate of change = \frac{0-(-6)}{2-0} = \frac{6}{2} = 3
