Answer:
-
Step-by-step explanation:
To get the slope you have to find the difference in Y and put it over the difference in X. (x2-x1)/(y2-y1). You plug in the points and you get -1/2
Answer:
x = - 1 ± i 
Step-by-step explanation:
Given
3x² = - 12 - 6x ( add 6x to both sides )
3x² + 6x = - 12 ( divide through by 3 )
x² + 2x = - 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = - 4 + 1
(x + 1)² = - 3 ( take the square root of both sides )
x + 1 = ±
= ± i
( subtract 1 from both sides )
x = - 1 ± i 
Answer:
5b -5
Step-by-step explanation:
5(b - 1)
we apply distributive property:
5*b -5*1
5b -5
Answer:
Step-by-step explanation: Area =length × width
7050m^2 = X× 75m
7050 =75X
Divide both sides by 75
7050÷75 =75÷75
74m= X
Answer:
300 min or 5 hours
Step-by-step explanation:
so if it pumps 0.5 gallons per minute than in 2 minutes it would pump 1 whole gallon so with that we know 1gallon=2 minutes.
so with that we multipy both sides by 150 which will be 150 galons=300 minutes or 5 hours
