Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
Answer:
No solution
Step-by-step explanation:
get rid of parentheses first by multiplying
5x-3=4x+8+x
combine like terms
5x-3=5x+8
-3=8
Answer:
is it asking which one is a y coordinate?
We first find the lines of the motion of each truck, then calculate its intercept.
Garbage truck:
m = (12 - 4) / (5 - 3)
m = 4
4 - y = 4(3 - x)
4x - y = 8
Dump truck:
m = (33 + 3) / (-4 - 5)
m = -4
33 - y = -4(-4 - x)
4x + y = 17
Adding the two equations to solve them, we get:
8x = 25
x = 25 / 8
y = 17 - 4(25/8)
y = 17 - 25/2
y = 9/2
The trucks' point of intersection is (25/8,9/2)
