Answer: 14y^3 - 8y^2 - 5y + 7

Step-by-step explanation:

Simplify and then combine like terms.

Original problem: 2y^2 + 7y + 11 - 8y^2 - 5y + 7

Simplified: 14y^3 + 11 - 8y^2 - 5y + 7

And then combined:  14y^3 + 11 - 8y^2 - 5y + 7

Combined continued: 14y^3 -8y^2 -5y +11 + 7

Final: 14y^3 - 8y^2 - 5y + 7

I already excluded anything that was written as "+ -(insert number)" because it would still end up to be "-" or a subtract/negative.

I hope this helps, and that I did it right.

Write an equation of the line that passes through a pair of points: -5, -2 3, -1
irinina [24]

Answer: option B is correct.

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The line passes through (- 5, - 2) and (3, - 1),

y2 = - 1

y1 = - 2

x2 = 3

x1 = - 5

Slope,m = (- 1 - - 2)/(3 - - 5) = 1/8

To determine the intercept, we would substitute x = 3, y = - 1 and

m = 1/8 into y = mx + c. It becomes

- 1 = 1/8 × 3 + c

- 1 = 3/8 + c

c = - 1 - 3/8 = - 11/8

The equation becomes

y = x/8 - 11/8

Write the name of each angle arm<br> A to O to C
tester [92]

Answer:

∠AOC

Step-by-step explanation:

The statement "A to O to C" is talking about each of the points that form an angle. Each point is given a letter as its name.

The symbol ∠ <u>means angle</u>.

You need two lines to form an angle, and you need two points to form a line. By reusing one of the points, you need three points to form an angle. The point that is being reused is always the point in the middle, in this case, that point is called 'O'.
