Answer:

1 would complete the square

Step-by-step explanation:

In order to solve this you have to remember the formlua for the perfect quadratic trinomial:

a^2 + 2 ab +b^2=0

IN the example you have A^2 and 2ab, since A=1, then the 2x will resulto from the multiplication of b and a multiplied by 2, so we just have to divide 2x by 2x to get b:

\frac{2x}{2x}=1

So we get that b is 1.

Solve for y Please help I need a tip
Gwar [14]

Answer:

y = 4

Step-by-step explanation:

Step 1: Write equation

9/4y - 12 = 1/4y - 4

Step 2: Solve for <em>y</em>

  1. Subtract 1/4y on both sides: 8/4y - 12 = -4
  2. Simplify: 2y - 12 = -4
  3. Add 12 to both sides: 2y = 8
  4. Divide both sides by 2: y = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9/4(4) - 12 = 1/4(4) - 4

9 - 12 = 1 - 4

-3 = -3

prisoha [69]
Please write   (x4 – 2) ÷ (x + 1)  as  <span>(x^4 – 2) ÷ (x + 1).

We can find the remainder using synth. div. as follows:

      _________________
-1  /  1    0    0    0    -2
              -1    1   -1    1
     ------------------------------
         1   -1    1   -1    -1

The remainder is -1.</span>

Drupady [299]
Find the critical value or test statistic.
z = \frac{m - \mu}{\sigma/\sqrt{n}} = \frac{404.5 - 400}{24/\sqrt{144}} = \frac{4.5}{2} = 2.25

Find P(z > 2.25) using a normal distribution table

P(z > 2.25) = 0.0122
