After because if you use it before the discount then the final price will be 1.50 but if you use it after the discount, then the final price is 1 dollar . 4 dollar with 50% discount is 2 dollar, and 2-1 is 1. 4-1 is 3 and 3 dollar with 50% discount is 1.50 dollar

Twice the sum of a number and 11 is 34.
Maru [420]

<u>Answer:</u>

  • The number is 6.

<u>Solution:</u>

  • 2(x + 11) = 34
  • => 2x + 22 = 34
  • => 2x = 34 - 22
  • => 2x = 12
  • => x = 12/2
  • => x = 6

Hence, the number is 6.

Which solution value satisfies the inequality x – 6 ≥ –7?
Bond [772]

Answer:

B) x = 0

Step-by-step explanation:

To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.

Plug -5 into x

-5 – 6 ≥ –7

Combine like terms

-11 ≥ –7

This is false, -11 is not greater than or equal to -7.

Plug 0 into x

0 – 6 ≥ –7

Combine like terms

– 6 ≥ –7

This is true, -6 is greater than -7.

Plug -2 into x.

-2 – 6 ≥ –7

Combine like terms

-8 ≥ –7

This is false, -8 is not greater than or equal to -7.

Plug -7 into x.

-7 – 6 ≥ –7

Combine like terms

-13 ≥ –7

This is false, -13 is not greater than or equal to -7.

B) x = 0 is the only solution that is true and works, so that is your answer.

Have a lovely rest of your day! :)

Given f(x)=4x^3-3x^2+10 use the remainder theorem to find f(-2)
ozzi
To do this, you would need to use synthetic division.

-2 | 4 -3 10
-8 22
4 -11 32

Your reminder would be 32.

Sorry if my graph of synthetic division is a bit messy, you can only do so much on a phone!
