Answer:
no solution
Step-by-step explanation:
Suppose the system equations are:
y = (-1/4)x + 2 (1)
3y = (-3/4)x – 6 (2)
If we multiply equation (1) by 3:
3y = (-3/4)x + 6 (1)
3y = (-3/4)x – 6 (2)
then subtract it from equation (2):
0y = 0x – 12
0 = -12
This is not possible, therefore, the system equation has no solution

Basically you can buy 5 tacos, without spending all of the 5 dollars.
Answer:
Step-by-step explanation:
(x + 5)2 + 2 = 42.5
x*2 + 5*2 + 2 = 42.5
2x + 10 + 2 = 42.5
2x + 12 = 42.5
2x = 42.5 - 12
2x = 30.5
x = 30.5/2
x = 15.25
