Step-by-step explanation:



Y = 60x +150
we put our ^0 mph as our Multiplier os x and since Alfred already traveled the 150 miles... that is just added on.
(-2)(3*4+2(-2)(-5)) = -2(12+20) = -2(32) = -64
Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ <u>35x - 15y = -160</u>
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6
