<span>2/5 (x - 4) = 2x
2/5x - 8/5 = 2x
-2x +  2/5x =  8/5
- 8/5x = 8/5
x = -1
answer
</span><span>−1
</span>--------------------
<span>−ax + 4b > 9
-ax > 9 - 4b
x < (9-4b)/-a
x < (-4b +9)/-a </span>

answer is

Find the ordered triple of these equations. 2x + 5y - 3z = -5 3x + 2y + 7z = 15 5x - 4y + 6z = 34
svetoff [14.1K]
<h2>Ordered triple are (4,-2,1)</h2>

Step-by-step explanation:

We need to find ordered triple of  2x + 5y - 3z = -5 , 3x + 2y + 7z = 15 and 5x - 4y + 6z = 34

     2x + 5y - 3z = -5 -------------------------eqn 1

     3x + 2y + 7z = 15 -------------------------eqn 2

     5x - 4y + 6z = 34 -------------------------eqn 3

eqn 1 + eqn 2

     5x + 7y + 4z = 10 -------------------------eqn 4

eqn 4 - eqn 3

     11y - 2z = -24 -------------------------eqn 5

eqn 1 x 3

     6x + 15y - 9z = -15 -------------------------eqn 6

eqn 2 x 2

     6x + 4y + 14z = 30 -------------------------eqn 7

eqn 7 - eqn 6

     -11y + 23z = 45 -------------------------eqn 8

eqn 5 + eqn 8

           21 z = 21

                z = 1

Substituting in eqn 8

       -11y + 23 x 1 = 45

         -11 y = 22

              y = -2

Substituting in eqn 1

        2x + 5 x -2 - 3 x 1 = -5

        2x = 8

          x = 4

Ordered triple are (4,-2,1)

30.5 $ with a 5% tax rate
Vlad [161]

Answer:

$32.03

Step-by-step explanation:

Since there is a tax rate, you want to multiply $30.50 by 1.05 since you are adding tax to it and it is 5%.  You should get 32.025 as the result, but since you need to round it, it is $32.03.

Find all real zeros of the function y= -9x - 1
Svetllana [295]

Answer:  -1/9  which is <u>choice B</u>

Explanation:

The term "zeros" refers to the x intercepts.

Plug in y = 0 and solve for x.

y = -9x-1

0 = -9x - 1

9x = -1

x = -1/9
