Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
for 17.
we have that x=8 as one solution
then we have
x-8=0
so we know that


so we divide and get that

and we can factor it as

so the other solutions are
x-3 =0
x = 3
this is a normal division
Answer:
m= 5/2
Step-by-step explanation:
Points: (0, 2) and (4, 12)
Slope:
m=(y2-y1)/(x2-x1)
m=(12-2)/(4-0)
m=10/4
m= 5/2
It’s B because C is too much and A is to little for the correct answer
