First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
Answer:
24
Step-by-step explanation:
4 x 2 = 8 so 8 x 3 = 24
Answer: 7/10
Step-by-step explanation:
2/5+3/10=4/10+3/10=7/10
Answer:
A; D; E
Step-by-step explanation:
Because they are outside of the triangle. That is what exterior means.
