Y = -2x + 5 remember Y = mx(slope) + b (y-int)
Answer:
b=1
Step-by-step explanation:
2b+1+2b=3b+2b
4b+1=5b(Simplify both sides of the equation)
4b+1−5b=5b−5b(Subtract 5b from both sides)
−b+1=0
−b+1−1=0−1(Subtract 1 from both sides)
−b=−1
−b
−1
=
−1
−1
(Divide both sides by -1)
b=1

Answer:
468 sq. ft.
Step-by-step explanation:
A = 1/2 (a + b) (h)
= 1/2 (52) (18)
= 468 sq. ft.
Answer:
-22/3 =x
Step-by-step explanation:
(4x-4) /(x+4) = 10
Multiply each side by (x+4)
(4x-4) /(x+4) * (x+4) = 10 * (x+4)
(4x-4) = 10 * (x+4)
Distribute
4x-4 = 10x+40
Subtract 4x from each side
4x-4-4x = 10-4x+40
-4 = 6x+40
subtract 40 from each side
-4 -40 = 6x+40-40
-44 = 6x
Divide each side by 6
-44/6 = -6x/6
-22/3 =x
