Answer:
[tex]\frac{-9}{12}[/tex]
Step-by-step explanation:
First, we need to isolate y.
1. Subtract 12x from both sides.
-9y=-12x+135
2. Divide by -9 in order to isolate y.
[tex]y=\frac{12}{9} x-15[/tex]
3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].
Anyone know this one? Quick!
4(x – 5) + (3x + 15) – 5x
Answer:
4(x-5)+(3x+15)-5x
4x-20+3x-20+15=0
collect like terms
4x-5x+3x-20+15=0
2x-5=0
2x÷2=5÷2
x=5÷2
Factor.
9y2 - 12y - 12 Please put it as (x+b) (x+b) form
Answer:
3(3y+2)(y-2)

How many soap cakes can be placed in a box of size 56 cm x 0.4 m 0.26 m, if the size
of a soap cake is 7 cm x 5 cm x 2.5 cm?
Answer:
length of box = 56cm
breadth = 0.4m = 40cm
height = o.25m = 25cm
Volume of Box = Volume of soap × n
n = number of soaps.
LBH = lbh × n
56 × 40 × 25 = 7 × 5 × 2.5 × n
n = 56×40×25/35×2.5
n = 56000/87.5
n = 640
so, 640 soaps can be placed in the box.
help with this pleaseeee
Can anyone help please
Answer:
Well multiplication is the inverse of additon. And when multiplying you add the exponents.

Please help me it would be helpful
only simplify, don’t solve please. thank you!
Answer:
4x
Step-by-step explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
Simplifying is the same as solving this question. I'll give steps instead.
x - 8 + 3x + 8
x + 3x - 8 + 8 (Arrange the equation)
(x + 3x) (- 8 + 8) (Parentheses the like terms together)
(4x) (0) (Solve)
4x (Simplified)
