Answer:

7x^2

Step-by-step explanation:

-5x^2+12x^2

combine like terms, so we would add -5 and 12 together, since they both end with x^2, they are alike terms.

We would end up with 7 for our sum, next you would just add x^2 to the end which would get us our answer of 7x^2

Which of the following points lie in the solution set to the following system of inequalities?

Oksana_A [137]

A. NOT

(-5, 2) → x = -5, y = 2

y ≤ x - 5 → 2 ≤ -5 - 5 → 2 ≤ -10 FALSE

B. YES

(5, -2) → x = 5, y = -2

y ≤ x - 5 → -2 ≤ 5 - 5 → -2 ≤ 0 TRUE

y ≥ -x - 4 → -2 ≥ -5 - 4 → -2 ≥ -9 TRUE

C. NOT

(-5, -2) → x = -5, y = -2

y ≤ x - 5 → -2 ≤ -5 - 5 → -2 ≤ -10 FALSE

D. NOT

(5, 2) → x = 5, y = 2

y ≤ x - 5 → 2 ≤ 5 - 5 → 2 ≤ 0 FALSE

What is one solution of the equation x^2 - 21.75x = -15.75? <br><br>thank you for the help!

Shalnov [3]

To determine the solution of the given equation, we can use the quadratic formula which is expressed as:

x = (-b +/- √b^2 - 4ac ) / 2a

where a, b and c are the coefficients of the equation ( ax^2 + bx + c = 0)

USing the formula above we obtain the values:

x = 21
x = 3/4

Hope this answers the question. Have a nice day.
