Answer: Graph A and Graph C hope this helps
Step-by-step explanation:
<span>let x is the number
2x + 18 = 9 - 4x
If solve for x
2x +4x = 9 -18
6x = -9
x = -9/6
x = -3/2</span>
A. (6.4=.8m) Divide both sides by .8 Answer: m=8
b. (-2.8p=4.2) Divide both sides by -2.8 Answer: p=0.071
c. (-4.7k=10.81) Divide both sides by -4.7 Answer: k=2.3
Answer:
Step-by-step explanation:
0=2x+4
-4 on both sides
-4=2x
divid both sides by 2
-2=x
so x=-2
then y
y=2*-2+4
2*-2=1
y=1+4
y=5
