215.
The 2 in 5,621 is equal to 20 while 2 in 215 is equal to 200, which is ten times the prior one.
Answer:
d. 9.25
Step-by-step explanation:
g(f(3.5)) = g(3.5²) = g(12.25) = 12.25 -3 = 9.25
_____
<em>Creating the composite function first</em>
The composition (g ∘ f)(x) means g(f(x)). That is, the value of f(x) is used as the argument for function g.
g(f(x)) = g(x²) = x² -3
Then g(f(3.5)) = 3.5² -3 = 12.25 -3 = 9.25
if you multiply 10.4x5x8 it equals 416 millimeters
Let's plug in (18,10) into each answer choice until we find the one that has it as a solution.
A) 2x - y = 26
2(18) - 10 = 26
36 - 10 = 26
26 = 26
Your answer is A.
I'll just do the rest to show that you the they are incorrect.
B) x + y = 18
18 + 10 = 18
28 ≠ 18
C) 2x - 2y = 36
2(18) - 2(10) = 36
36 - 20 = 36
16 ≠ 36
D) x - y = -28
18 - 10 = -28
8 ≠ -28
Your answer is A) 2x - y = 26.
