Answer:
Step-by-step explanation:
What variable are you solving for?
-4x+y=29
y=29-(-4x)
y=29+4x
y=4x+29
----------------
-4x=29-y
-4x=-y+29
x=1/4y+29/-4
y=1/4y-29/4
(0,30), (1,20)
(20-30)/(1-0) = -10/1 = -10 slope
We know y intercept is 30
Equation: y = -10x + 30
Answer:
-16
Step-by-step explanation:
Anything written in the form of a(b) or (b)a means a × b:
(-4)4 means -4 × 4 which is -16 (a positive and a negative multiplied together make a negative).

Answer:
She need <u>96 square feet</u> carpet to cover the room.
Step-by-step explanation:
Given:
Tina covers the floor of a room with carpeting. She uses carpet squares that measure one foot on each side.
Now, to find carpet squares does she need to cover a room that 8 feet wide by 12 feet long.
So, the dimensions of room are:
Length = 12 feet.
Width = 8 feet.

<u><em>Area of room = Length × width</em></u>


Therefore, she need 96 square feet carpet to cover the room.
Answer:
(12x²+4)(x-5)
Step-by-step explanation:
To factor the expression factor by grouping.
(12x³ - 60x²) + (4x - 20)
12x²(x - 5) 4(x-5)
(12x²+4)(x-5)
