Answer:
310.6m^3
Step-by-step explanation:
7x - 5y = -140
Solve for y.
7x + 140 = 5y
5y = 7x + 140
y = (7/5)x + 28
To plot the line, draw a point at (0, 28).
Then go up 7 units and right 5 units and draw a point there.
Connect the two points with a segment and extend it in both directions.
Answer:
answer C
Step-by-step explanation:
<span>If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5
you first plug in 5 for x in both equations...
(2(5)^2-4(5))=f(x)
5-2(5)=g(x)
now you evaluate...
(2(25)-20)-5-10
50-30-15
20-15=5
Answer:
5
