Answer:
y=3x+10
Step-by-step explanation:
y-4=(x+2)3
y-4=3x+6
y =3x+10
Answer:
(3,1)
Step-by-step explanation:
Multiplying the second equation by 3, we get
-12x-6y=-42.
Now, adding this to the first equation, we get
-13x=-39
Therefore, x=3
plugging in x=3 to the first equation, we get that
-3+6y=3
adding 3 to both sides,
6y=6
therefore, y=1
175 - 97.5 = 77.5
77.5 / 97.5 = 0.7948 = 79.5%
