Easy, take your problem,

-5(a-6)+2a

Multiply the 5.

-5a+30+2a

Then just add apples and oranges.

-5a+2a= -3a.

Making your equation -3a+30.

-5(a-6) + 2a \\ \\ -5a + 30 + 2a \\ \\ (-5a + 2a) + 30 \\ \\ -3a + 30 \\ \\

The final result is: -3a + 30.

Answer:

x=−2 and y=−1

Step-by-step explanation:

<u>Problem:</u>

Solve y=x2;y=−x−3

<u>Steps:</u>

I will solve your system by substitution.

y=1/2x;y=−x−3

Step: Solve y= 1/2x for y:

Step: Substitute 1/2 x for y in y=−x−3:

y=−x−3

1/2x= =−x−3

1/2x+x=−x−3+x(Add x to both sides)

3/2x = -3

3/2x/3/2 = -3/3/2 (Divide both sides by 3/2)

x=−2

Step: Substitute −2 for x in y=1/2x:

y=1/2x

y=1/2(-2)

y=−1(Simplify both sides of the equation)

<u>Answer:</u>

x=−2 and y=−1

How do you solve this?
natali 33 [55]
Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.

The graph has y-intercept (0, 6) and contains the point (2, 1).
prisoha [69]

Answer:

5x + 2y = 12

Step-by-step explanation:

Direction factor = (2, 1) - (0, 6) = (2, -5)

So, normal factor = (5, 2)

Line: 5x + 2y = k

(0, 6) -> L: 0 + 12 = 12 = k

L: 5x + 2y = 12
