<h3>1)</h3>

• 6x -2(x -5) = -2 . . . . given

• 6x -2x +10 = -2 . . . . X Cameron errored here. When multiplying -2 by -5, the result is 10, not -10.

• 4x +10 = -2 . . . . . . x terms are correctly collected

• 4x +10 -10 = -2 -10 . . . . add the opposite of the constant on the left

• 4x/4 = -12/4 . . . . divide by the x-coefficient

• x = -3 . . . . . . . . . . simplify

<h3>2)</h3>

• 11x -10 = -34 . . . . combine like terms

• 11x -10 +10 = 34 +10 . . . . addition property of equality

• 11x = 44 . . . . . . . . simplify

• 11x/11 = 44/11 . . . division property of equality

• x = 4 . . . . . . . . . . . simplify

Answer:

a) \ 6^2 \times 6^3 = 6^{2+3} = 6^5 = 7776\\\\b)\ \frac{(-3)^5 }{(-3)^2} = (-3)^{5-2} = (-3)^3 = -27\\\\c)\ [(-2)^3]^4 = (-2)^{3\times 4} = (-2)^{12} = 4096 \\\\d)\ (\frac{1}{999})^0 = 1,  anything \ raise \ to \ zero = 1\\\\e) \ (\frac{4}{3})^{-2} = 4^{-2} \times 3^2 = \frac{9}{16}\\\\f) \ \frac{2^5 \times 2^9}{2^{16}} = 2^{5+9-16} = 2^{-2} = \frac{1}{4}

True or false ??? Someone plz helpppp !!! this quiz is hard
elena-s [515]

Answer:

True.

Step-by-step explanation:

Since they are all on the number line  and some are negative, you would go back and go up instead. If you were to check again, it would be all on the number line.

Simplify fully: X^2+3x-4/ 2x^2-5x+3
sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step  1  :

           2

Simplify   —

           1

Equation at the end of step  1  :

 ((((x2)+3x)-(2•x2))-5x)+3

Step  2  :

Equation at the end of step  2  :

 ((((x2) +  3x) -  2x2) -  5x) +  3

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  -x2 - 2x + 3  =   -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2     Factoring  x2 + 2x - 3

The first term is,  x2  its coefficient is  1 .

The middle term is,  +2x  its coefficient is  2 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   2 .

     -3    +    1    =    -2

     -1    +    3    =    2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  3

                    x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (x+3)  •  (x-1)

            Which is the desired factorization

Final result :

 (-x - 3) • (x - 1)
