Answer:
Output value for the following function is 4
Step-by-step explanation:
Given:
The input value are the value of x

Input value is 1
We substitute the value 1 for the input variable x in the given function.




The output value are the value of y
Therefore, for an input of 1, we have an output of 4.
Answer:
52
Step-by-step explanation:
the answer is 52 because all the angles have to add up to 360 and 128+126+54=308 and 360-308=52
L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=3w-4
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64
1w-4= 4-1w
+1w +1w
——————
2w-4=4
+4 +4
—————
2w=8

2. 2
w= 4
Answer:
x = -14
Step-by-step explanation:
x + 6 = 4x/7
7x + 42 = 4x
7x - 4x = -42
3x = -42
x = -42 ÷ 3
x = -14
