Answer:

Step-by-step explanation:
The first two x-values, -4 and 0, fall in the first part of the function definition.
There is no function definition for x = 4, as the second part only applies for x > 4.
The last x-value, 8, falls in the second part of the function definition.
The function is evaluated by putting the x-value where x is in the expression and doing the arithmetic. For example, ...
h(-4) = -(-4+1)^2 +7 = -(-3)^2 +7 = -9 +7 = -2
h(0) = 6
h(4) = undefined
h(8) = -8/3
The answer is c because when you multiply 60 and 0.07 youranswer is 4.2
Answer:
x = 2.25, y = 2.5
Step-by-step explanation:
-2x + 2y = -2 .............equ (1)
2x + 3y = 12 .............equ (2)
equ (1) + equ (2)
-2x + 2y = -2
+ 2x + 2y = 12
=> 0 + 4y = 10
=> 4y/4 = 10/4
=> y = 2½
Substitute for y in equ (2)
i. e, 2x + 3y = 12
=> 2x + 3(10/4) =12
=> 2x + 30/4 = 12
=> 2x = 12 - 30/4
=> 2x = (48 - 30)/4
=> 2x = 18/4
=> 8x = 18
=> x = 18/8
=> x = 2^2/8 or 2.25
x = 2.25, y = 2.5
