Idk sorry
Step-by-step explanation:
Answer:
-16
Step-by-step explanation:
distribute the 4: 4x-8=-72
add 8 to both sides: 4x=-64
divide by 4: x+-16
f(4)=4+21
4+21=25
f(4)=25
You insert in 4 into the x and then solve from there and you have you're answer. So the output for that function is 25.
It doesn't say how many numbers but if it's out of ten then it'll be
Answer:
Please find the answer below
Step-by-step explanation:
2a-b+c= -5 ----(A)
a-b+c= -5 ------(B)
2a+b =5 -------(C)
from equation A subtracting 2a from both sides we get
-b+c = -5-2a
Substituting this value in B
a-5-2a=-5
a-2a-5+5=0
-a=0
a=0
Putting this value in C
2(0)+b=5
b=5
Putting these values in B
0-5+c=-5
c=0
We do not have any option with these solutions . Hence, it seems that there is something missing from the equation.
