Answer:

x=7

Step-by-step explanation:

Simplifying

-1(8 + -3x) = 13

(8 * -1 + -3x * -1) = 13

(-8 + 3x) = 13

Solving

-8 + 3x = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 3x = 13 + 8

Combine like terms: -8 + 8 = 0

0 + 3x = 13 + 8

3x = 13 + 8

Combine like terms: 13 + 8 = 21

3x = 21

Divide each side by '3'.

x = 7

Simplifying

x = 7

Complete the synthetic division problem below. What is the quotient in polynomial form?
stellarik [79]
The polynomial would be 2x+5.

We bring down the first number inside the box, 2, unchanged.

    _______
-1|  2   7   5
    _______
      2

Now we multiply that 2 by the number outside, -1:
    _______
-1|  2   7   5
    <u>      -2     
</u>      2

Now we add the two numbers in the middle column:
    ________
-1|   2   7   5
    <u>       -2      </u> 
       2   5

Multiply the 5 we brought down by the -1:
    ________
-1|   2   7   5
    <u>       -2  -5 
</u>       2   5   

Add the numbers in the last column:
    ________
 -1|   2   7   5
     <u>       -2  -5
</u>        2   5   0

The 3 numbers under the box represent the coefficients of x² and x, as well as the constant.  When we finish, we no longer have an x², but start at the next level down, which would be x.  2 would be the coefficient of x and 5 would be the constant, with 0 remainder.

The line that contains the point Q( 1, -2) and is parallel to the line whose equation is y - 4 = 2/3 (x - 3)
Musya8 [376]

Answer:

y + 2 = \frac{2}{3}(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = \frac{2}{3}(x - 3) ← is in point- slope form

with slope m = \frac{2}{3}

Parallel lines have equal slopes, thus equation of parallel line

with m = \frac{2}{3} and (a, b) = Q(1, - 2) is

y - (- 2) = \frac{2}{3}(x - 1) , that is

y + 2 = \frac{2}{3}(x - 1)
