Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

−28+4x=4(x−7)

Step 1: Simplify both sides of the equation.

−28+4x=4(x−7)

−28+4x=(4)(x)+(4)(−7)(Distribute)

−28+4x=4x+−28

4x−28=4x−28

Step 2: Subtract 4x from both sides.

4x−28−4x=4x−28−4x

−28=−28

Step 3: Add 28 to both sides.

−28+28=−28+28

0=0

Answer:

All real numbers are solutions.

Answer:

x^2 + 5 x + =0

Step-by-step explanation:

We need to factor this trinomial by grouping.

The first step in this process consists of splitting the middle term into two terms.

In our example, 5x  has been split into 2x and .

Notice that one common factor can be factored from the first 2 terms, and another from the second 2 terms

Answer:

y =  x² - 8x + 17

Step-by-step explanation:

Recall this formula:

y = a(x-h)² + k

Original equation was y = x², which in this form looks like

y = 1(x - 0)² + 0

If the shape of the graph didn't change, that means that a (the compressor/intensifier) stayed the same (a - value) meaning we can write the equation as..

y = (x-h)² + k

Remember, (h, k) is the vertex, which looking from your graph is at (4, 1)

y = (x - 4)² + 1

y = x^2- 8x + 16+1

y = x² - 8x + 17

Answer:

see explanation

Step-by-step explanation:

c = a - 2b

  = < 4, 5, 6 > - 2 < 1, 2, 3 > ← multiply each component by 2

  = < 4, 5, 6 > - < 2, 4, 6 >  ← subtract corresponding components

  = < 4 - 2, 5 - 4, 6 - 6 > = < 2, 1, 0 >

| c | = \sqrt{2^2+1^2+0^2} = \sqrt{4+1+0} = \sqrt{5}

-------------------------------------------------------------------------------------------------

sum the product of corresponding components

u.v = (3 × 2) + (- 2 × - 1) + (4 × - 6) = 6 + 2 - 24 = - 16

Show your work<br> 4(2x - 6) = 10x - 6
Elden [556K]

4.(2x - 6) = 10x - 6

4.2x - 4.6 = 10x - 6

8x - 24 = 10x - 6

-24 + 6 = 10x - 8x

-18 = 2x

x = -9
