To figure this out, we need to solve for the inequality. A quick way is to plug in an answer choice for x.
For example, answer choice "A.)";
3(4) -4 <_ 8
We plugged in 4 for x.
Let's see if A.) is correct.
3(4) -4 <_ 8
12 - 4 <_ 8
8 <_ 8

This is the GREATEST possible integer, as the question asks for what the highest possible number would match the inequality.

Your correct answer choice is "A.)"

I hope this helps!

What error did zacharias make? the –5 should be 5. the 52 should be –52. the 2 in the numerator should be –2. the 2 in the denom
Contact [7]

The error made by zacharias in solving the quadratic equation 0 = -2x² + 5x - 3 using quadratic formula is; the 2 in the numerator should be –2.

<h3>Quadratic equation</h3>

There are four methods of solving quadratic equation. Namely;

  • Factorization method
  • Completing the square method
  • Graphical method
  • Formula method

0 = -2x² + 5x - 3

  • Using quadratic formula

x = -b ± √b² - 4ac / 2a

where,

  • a = -2
  • b = 5
  • c = -3

x = -b ± √b² - 4ac / 2a

x = -5 ± √5² - 4(-2)(-3) / 2(-2)

= -5 ± √25 - (24) / -2

= -5 ± √1 / -2

= -5/2 ± 1/2

= -5/2 - 1/2 or x = -5/2 + 1/2

= -5-1 / 2 or -5+1/ 2

x = -6/2 or -4/2

x = -3 or -2

Therefore, the solution to the quadratic equation is x = -3 or -2

Need help on this question writing linear equations
Mrrafil [7]

if you look at delta y over x, you'll notice it always equals 2

i.e (22-2)/10-0 = 20/10 = 2

or (14-2)/6-0 = 12/6 = 2

or even (22-8)/10-3 = 14/7 = 2

This means that m (slope) is 2.

Now as for b. b is the y intercept and that value occurs when x = 0. On the table, when x = 0 y = 2 so b = 2.

y = mx + b becomes

y = 2x + 2
