Answer:

Options C, D and F are correct.

Step-by-step explanation:

The factors of 5x^{2}-16x+12 are 2 and \frac{6}{5}

So, option C is correct. (x-2) is a factor or x=2

Option D is also correct. 2 is the root of f(x) = 5x^{2}-16x+12

Putting 2 in place of x we get 5(2)^{2} -16(2)+12

5*4 -32 +12=0

Option F is correct because the remainder is zero in last line.(5x-6+0)

The answer is C, D, and F. We know it is C because x-2 you would put a positive 2 and that is what is done. We know it is D because if you look at the graph that's where it would touch. We know it is F because the last number below the line is 0.

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

-x + 4y = -8

-5x - 4y = -16

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine equations:                     -6x = -24
  2. Isolate <em>x</em>:                                        x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                   -x + 4y = -8
  2. Substitute in <em>x</em>:                      -4 + 4y = -8
  3. Isolate <em>y</em> term:                       4y = -4
  4. Isolate <em>y</em>:                                y = -1

Find the coordinates of the vertex of the following parabola algebraically. Write your answer as an (x,y)(x,y) point.
Serga [27]

Answer:

(8,-3)

Step-by-step explanation:

The given parabola is

y =  - 3 {x}^{2}  + 48x  - 195

We factor -3 from the first two terms to get:

y =  - 3( {x}^{2}   - 16x)  - 195

Add and subtract the square of half the coefficient of x

y =  - 3( {x}^{2}   - 16x + 64)   + 3 \times 64- 195

y =  - 3 {(x - 8)}^{2}  + 192 - 195

We simplify to get:

y =  - 3 {(x - 8)}^{2}  - 3

We compare this to y=a(x-h)²+k,

The vertex is (h,k)=(8,-3)

Is this for area and perimeter? If so, first make the fraction a decimal, (that would be 3.5). Then, for permeter, add 3.5 + 3.5 + 9 + 9, which is 25, for area, multiply 3.5 by 9, which is 31.5. Hope this helped!
