Answer:

Option The graph will be a dashed line with a y-intercept of negative eight and a slope of three. The graph will be shaded above

the line

Step-by-step explanation:

we have

$y>3x-8$

The solution of the inequality is the shaded area above the dashed line The equation of the dashed line is $y=3x-8$

The slope of the dashed line is positive $m=3$

The y-intercept of the dashed line is -8

Using arithmetic operations, rewrite this polynomial in standard, simplest form.

dangina [55]

(3x2 + 9x + 6) − (8x2 + 3x − 10) + (2x + 4)(3x − 7)

First distribute the (2x+4)(3x-7) to get 6x2-2x-28
After this just add the like terms for all parts of the expression.
(3x2-8x2+6x2)+(9x-3x-2x)+(6+10-28)
x2+4x-12

So you answer is x2+4x-12

alexandr402 [8]

$- 17y - 16z + 4$

Step-by-step explanation:

1) Collect like terms.

$( - y - 16y) + (9z - 25z) + 4$

2) Simplify.

$- 17y - 16z + 4$

So, therefor, the answer is -17y - 16z + 4.
