ANSWER

c. 6x^2 + 2x + 8, quadratic trinomial

EXPLANATION

The given polynomial is

$8 - 4 {x}^{2} + 10 {x}^{2} + 2x$

We regroup the terms to get;

$10 {x}^{2} - 4 {x}^{2} + 2x + 8$

Simplify now to obtain:

$6 {x}^{2} + 2x + 8$

This is a quadratic polynomial function based on the degree.

It is also a trinomial based on the number of terms.

The correct answer is C

Answer:

Choice c is the answer.

Step-by-step explanation:

We have given a expression.

8 - 4x² + 10x² + 2x

We have to rewrite the given expression in standard form.

ax²+bx+c is standard form of quadratic expression.

Adding the like terms , we have

8+(-4+10)x²+2x

8+(6)x²+2x

writing above expression in decreasing power order, we have

6x²+2x+8

Degree : 2

Number of terms: 3

so. it is a quadratic trinomial.

Hence, Choice c is the answer.

I really need help with this problem steps

Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20

Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)
Let me know if I have answered your question

Answer:

She can make three shirts and will have 7/56 left.

Step-by-step explanation:

49/56-14/56=35/56 (one shirt) 35/56-14/56=21/56 (two shirts) 21/56-14/56=7/56 (three shirts)

What is (-4,5) and (8,-1)

Musya8 [376]

Answer:

the slope-intercept equation of a line that passes through the coordinate (-4,5) and (8,-1) is

$y = - 0.5x + 3$

Step-by-step explanation:

1) Apply the slope formula; y^2 - y^1 divided by x^2 - x^1

y^2 is -1

y^1 is 5

x^2 is 8

x^1 is -4

-1 - 5 = -6

8 - (-4) = 12

-6/12 is -1/2 or -0.5

2) To find the y-intercept, hoose either of the coordinates and replace y, m, and x in the y= mx+b formula.

5= -0.5(-4) + b

5= 2 + b

3= b
