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.

Step-by-step explanation:

(8y^2-5y+7) - (2y^2+7y+11)

(8y^2-5y+7)-2y^2-7y-11

Combine like terms:

6y^2-12y-4

In the coordinate plane, line p has a slope of 8 and y-intercept (0,3). What are the slope and y-intercept of line r?
Aleksandr [31]

Answer:

y  = 8x + 3

Step-by-step explanation:

The line we are describing here is line p;

 slope of line p = 8

  y- intercept = (0,3)

y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0

So;

  Slope of the line = 8

   y-intercept  =  3

Equation of the line;

       y  = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

      y  = 8x + 3

Solve for x: 6 over x equals 4 over 8
Talja [164]

Answer:

For the given expression, x = 12.

Step-by-step explanation:

Here, in the given expression:

6 over x equals 4 over 8.

Now, 6 over x = \frac{6}{x}

and  4 over 8  =  \frac{4}{8}

So, here  \frac{6}{x}   =\frac{4}{8}\\ \implies x = \frac{6 \times 8}{4}  = 12

⇒ x = 12

Hence, for the given expression, x = 12.
