2x + 10 - 8x = -38 2(x + 5) = -2
-10 = -5(x +9)
6 - 7x - 19 = -83
3(3x - 4) = 24
can anybody help me on all of these questions? quick and thank you so much!

Step-by-step explanation:

1. 2x+10-8x = -38

  -6x + 10 = -38

  -6x = - 48

   x = 8

2. 2(x+5)=-2

   2x + 10 = -2

   2x = -12

    x= -6

3. -10 = -5(x+9)

   -10 = -5x - 45

   35 = -5x

    x = -7

4. 6 - 7x - 19 = -83

  -13 - 7x = -83

   -7x = -70

    x = 10

5. 3(3x-4) = 24

   9x - 12 = 24

   9x = 36

   x = 4

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
