Metric system is based on powers of 10
(x/y) + 2z.......when x = 6, y = 0.3, and z = -2.4
now we sub
(6/0.3) + 2(-2.4) =
20 - 4.8 =
15.2 <====
Answer:
100 and 120
Step-by-step explanation:
I might be wrong but there were no answers
The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.
The equation says when X is ≤ -4 use the first equation
So h(-4) = -1/2(x) -15
= -1/2(-4) -15
= 2 -15
= -13
When x = -2 (h(-2) ) use the 2nd equation:
h(-2) = 20-3x^2
=20-3(-2)^2
= 20-3(4)
=20-12
=8
Now you have -13 + 3(8)
= -13 + 24
=11
The answer should be 11
