The slope is the coefficient of the variable. In this case, -1/4 is before the x. So the answer is C
Answer:
4.5 x 10^11
Pretty simple, and Im just typing bc it needs to be 20 characters also use m a t h w a y.
X = plan A and y = plan B
7x + 9y = 720
5x + 3y = 360.....multiply by -3
---------------
7x + 9y = 720
-15x - 9y = -1080 (result of multiplying by -3)
---------------add
-8x = - 360
x = -360/-8
x = 45 minutes <== plan A
5x + 3y = 360
5(45) + 3y = 360
225 + 3y = 360
3y = 360 - 225
3y = 135
y = 135/3
y = 45 minutes <== plan B
so both plans last 45 minutes <==
