4 times a number is 32 less than the square of that number. Find the negative solution.
zvonat [6]

Answer:

<u>The negative solution is -4</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

x = a number

4x = x² - 32 (4 times a number is 32 less than the square of that number)

2. Let's solve for x and find the negative solution:

4x = x² - 32

-x² + 4x + 32 = 0

x² - 4x - 32 = 0 (Multiplying by - 1)

(x - 8) (x + 4) = 0

(x₁  - 8) = 0

(x₂ + 4) = 0

x₁ = 8

<u>x₂ = -4</u>

<u>The negative solution is -4</u>

–6​x ​≥ ​72 solve (please help me because I'm not sure if my answer is correct or not)
Alik [6]

Yes you are correct. You divide both sides by -6 to isolate x. Dividing both sides by a negative number will flip the inequality sign.

If you need to graph this, then you'll have a closed circle at -12 on the number line. Then you'll have shading to the left of this closed circle. The closed circle indicates "include this endpoint as part of the shaded solution set".
