5. 
First plug the value of x into the equation
 2(-2y-12)+y=9
then solve for y
2(-2y)+2(-12)+y=9 \\ -4y+(-24)+y=9 \\ -4y-24+y=9 \\ -3y-24=9 \\ -3y=33 \\ \frac{-3y}{-3}= \frac{33}{-3} \\ y = -11

6. Do the same steps 
5(-y-1)+y=-13 \\ 5(-y)+5(-1)+y=13 \\ -5y+(-5)+y=13 \\ -5y-5+y=13 \\ -4y-5=13 \\ -4y=18 \\ \frac{-4y}{-4}= \frac{18}{-4} \\ y=-4.5

uysha [10]

Answer:

y = \frac{4}{3} x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (6, 10) ← 2 points on the line

m = \frac{10-2}{6-0} = \frac{8}{6} = \frac{4}{3}

The line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = \frac{4}{3} x + 2 ← equation of line

puteri [66]

Answer:

15 days

Step-by-step explanation:

Since he used both of the weights today, he will only do both on the day they come together.

weights: 3 days, 6 days, 9 days, 12 days, 15 days

machine: 5 days, 10 days, 15 days

Because the numbers both were the same on 15 days, then that is when he will do both of them

Select all the expressions that are equivalent to 18+4(m−3)+4m.
SOVA2 [1]

Answer:

<h2>One of them i believe is 2 (3+4m) and another one is 6+8m</h2>

Step-by-step explanation: so for the first one you have your equation 18+4(m-3)+4m you take the second part and do 2(9+2(m-3)+2m) then after that you get 2(9+2m-6+2m)  and you get you first answer 2(3+4m)

Your second probelm 6+8m you have your equation 18+4(m-3)+4m  you do 18+4m-12+4 and you subtract all th likes terms so you get 6+8m

Hope this helps!
