Answer:
132−15+12
Step-by-step explanation:
The shirts were sold at $15 each.
The slope would be 2. the equation to find slope is m= y2-y1/x2-x1 , so 0- -4 is 4, and 2-0 is 2, and 4/2 is 2.
Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)
