Answer:

3y-12

Step-by-step explanation:

b=y+2, and c=y-7. We know that b=y+2, so b+2c can be written as y+2+2c. We also know c=y-7, so we can write it as y+2+2y-14, so we have 3y-12.

<u>Answer:</u>

c= -1/2

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

4 /3 = −6c − 5/ 3

Step 1: Simplify both sides of the equation.

4 /3 =−6c + −5 /3

Step 2: Flip the equation.

−6c + −5 /3 = 4/3

Step 3: Add 5/3 to both sides.

−6c + −5 /3 + 5 /3 = 4/3 + 5 /3 −6c

Step 4: Divide both sides by -6.

−6c −6 = 3 − 6 c = −1 /2

Natalka [10]

Answer:

#2 option: $\frac{2}{3}$

Step-by-step explanation:

$slope=\frac{rise}{run} =\frac{y^2-y^1}{x^2-x^1}$

$\frac{3-(-1)}{4-(-2)}=\frac{-4}{-6} =\frac{-2}{-3} =\frac{2}{3}$

= $\frac{2}{3}$
