3a+11=7a-13 with shown work​
DaniilM [7]

3a+11=7a-13

move 7a to the other side

sign changes from +7a to -7a

3a-7a+11= 7a-7a-13( combine like terms)

3a-7a+11= -13

-4a+11= -13

move 11 to the other side

sign changes from +11 to -11

-4a+11-11= -13-11

-4a= -13-11

-4a= -24

divide both sides by -4 to get a by itself

-4a/-4= -24/-4

Answer: a= 6

10. Solve for z: 2 + 8 - z = -24
iVinArrow [24]

Answer:

The answer is z = 34.

Step-by-step explanation:

1) Simplify 2 + 8 - z to 10 - z.

10 - z =  - 24

2) Subtract 10 from both sides.

- z =  - 24 - 10

3) Simplify - 24 - 10 to -34.

- z =  - 34

4) Multiply both sides by -1.

z = 34

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>z</u><u> </u><u>=</u><u> </u><u>34</u><u>.</u>

Find the equation f(x) = a(x - h)2 + k for a parabola containing point (3, 6) and having (1, -2) as a vertex. What is the standa
nlexa [21]

f(x) = 2 x^{2} -4x

Step-by-step explanation:

Step 1 :

Given, f(x) = a(x - h)2 + k

Point on the parabola is (3, 6)

Vertex (h,k) = (1,-2)

Step 2:

Substituting the vertex in the equation we have,

f(x) = a(x-1)2 -2

Substituting the point (3,6) in this we have,

6 = a(3-1)2 - 2 => 6 = 4a -2

=>  4a = 8 => a = 2

Step 3 :

Substituting the value for a and the vertex in the given equation we have

f(x) = 2(x-1)2 -2 = 2(x2 - 2x + 1) -2 = 2x2 - 4x

=> f(x) = 2 x^{2} -4x  which is the standard form
