Answer:

You need to get x by itself

(x = 1)

Step-by-step explanation:

1. Expand.

-12x - 3 - 8x = - 16 - 7x

2. Simplify

-20x - 3 = -16 - 7x

3. Add 20x to both sides.

-3 = -16 -7x + 20x

4. Simplify.

-3 = -16 + 13x

5. Regroup terms.

-3 = 13x - 16

6. Add 16 to both sides.

-3 + 16 = 13x

7. Simplify.

13 = 13x

8. Divide both sides by 13.

1 = x

9. Switch sides

x = 1

X is around 8.66666666, so you could possibly but that in fraction form like 8.666666/1 (8.6 repeating) and put it over one. I hope this helps!

Find the term that must be added to the equation x^2−6x=7 to make it into a perfect square.
Gnom [1K]

Answer:

Step-by-step explanation:

x^2-6x=7 is our equation

x^2-2*3*x= 7

So the term we will be adding is 3^2 since 3 the second term is 2*3*x

x^2-6x+9=7-9

We added 9 and substract it to keep the equation

(x+3)^2 = -2

Wich is impossible since a squared number is always positive

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Let's look at each option to which one is true with regard to the given functions on the graph.

The option that is correct is the option that shows where the graph of f(x) and g(x) intercepts or cut across each other.

Now, take a look at the graph, the line of both functions intercepts at x = -3. At this point, the value of f(-3) and g(-3) is equal to -4.

Therefore: f(-3) = g(-3)
