Answer:
2nd option, rectangle B
Step-by-step explanation:
After reflexion, the figure will be at the left side of x=-5
Answer:
Valid
Step-by-step explanation:
Add y to both sides then do the algebra
-3y = x...so we sub in -3y for x in the other equation
-x + 7y = 70
-(-3y) + 7y = 70
3y + 7y = 70
10y = 70
y = 70/10
y = 7
so we sub in 7 for y in either of the original equations to find x
-3y = x
-3(7) = x
-21 = x
so ur solution is (-21,7)
M=3 bc x(5) +3M(3•3) = 14 aka 9 + 5.
