Answer:
70
Step-by-step explanation:
Answer:
2y² + 14y - 15
Step-by-step explanation:
(2y² + 8y - 9) - (- 6y + 6)
Remove first parenthesis and distribute second by - 1
= 2y² + 8y - 9 + 6y - 6 ← collect like terms
= 2y² + 14y - 15
10) 7(2m+3)
11) 3(3r-1)
12) 2p(5q+4)
Answer:
1. The supply equation is y=10x-50
2. the demand equation is y=-10x+700
3. The solution for the system of equations is (75/2,325). This means That the demand and supply will be the same when the price is 37.50$
4. Write the x-coordinates in 10's and y-coordinates in 100's. Put 2 points for supply as (10,50) and (20,150) and connect them. For demand, put 2 points as (10,600) and (20,500) then connect the 2 points.
5. A) The equilibrium point is (75/2,325)
B) this compares because you can solve a system of equations by graphing or substituting.
