Answer:
9
Step-by-step explanation:
4+5 is equal to 9.
Answer:
All real numbers of x.
Step-by-step explanation:
5x+10=5(x+2) have the exact same equations on both sides.
5x+10=5x+10
If both are graphed, they will intersect each other for every value of x.
Answer:
Step-by-step explanation:
for x, then 7 = (x1+9) /2
14 = x1+9
5 = x1
for y , then 4 = (y1+7 ) /2
8 = y1 + 7
1 = y1
J = (5,1)
1: = 12x-39
2 = -11d+44
3 = 20y-15
4 = -22
5 = -4m+4
6 = 13h+21
7 = -6g+3
8= 13c-20
9 = -2q+12
your welcome cutie ;)
