Answer:
-8x+12
Step-by-step explanation:
Solve:
2(-5x + 10) + 2(x-4)= perimeter
-10x+20 + 2x-8= perimeter
-8x+12= perimeter
Hope this helps! :)
Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4
Answer: Translation: The school will build a fast soccer field that is 120m long and 60m wide, but around it there will be an 8m wide race track. Find the area of the terrain and the area of the track
Step-by-step explanation:
Answer:
1 no
2 I don't know
3 no
4 yes
5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept
