(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50
10x² - 45x + 50
5( 2x² - 9x + 10)
2x -5
x -2
5(2x - 5)(x -2)
make each equal to 0
2x - 5 = 0
x - 2 = 0
2x - 5 = 0 x - 2 = 0
2x - 5 (+5) = 0 x - 2 (+2) = 0 (+2)
2x = 5 x = 2
x = 5/2
x = 5/2 , 2
hope this helps
Answer:
c= (f-d)/ab
Step-by-step explanation:
- abc+d = f
- Subtract f from both sides so abc= f-d
- Divide by ab from both sides so c = (f-d)/ab
Answer:
He must work additional 8 hours.
Step-by-step explanation:
Because 1550.00/20=7.75
217.00/7.75=28
28-20=8
So,an additional of 8 hours
Part A:
<span>Max volume = Volume of container = 13 in x 7 in x 6 in = 546 in^3 </span>
<span>Part B: </span>
<span>1 cup = 14.4375 in^3 </span>
<span>
14 cups = 14.4375 in^3 x 7 = 202.125 in^3 </span>
<span>Part C: </span>
<span>Height of water = (202.125 in^3)/(13 in x 7 in) = 2.22 in.</span>
Answer:
y = 2x - 9
Step-by-step explanation:
y= mx + b
plug in slope
y = 2x + b
plug in points
1 = 2 (5) + b
simplify
1 = 10 + b
subtract 10 each side
-9 = b
plug in to original equation
y=2x - 9
