Which of the following is(are) the solution(s) to |5x+2|=8 ?

slega [8]

Answer:

x = 6/5 or x = -2

Step-by-step explanation:

We need to solve:

|5x+2|=8

We know that |u|=a the u = a and u = -a

Now solving:

|5x+2|=8

5x +2 = 8 or 5x +2 = -8

5x = 8-2 or 5x = -8-2

5x = 6 or 5x = -10

x = 6/5 or x = -10/5

x = 6/5 or x = -2

So, x = 6/5 or x = -2

Quick algebra 1 question for 50 points!

saul85 [17]

Answer:

b. -x + y = 0

Step-by-step explanation:

Direct variation:

Direct variation means "y varies directly as x”:

$y \propto x \implies y=kx$

where k is the (non-zero) constant of variation.

To determine which of the given equations represents a direct variation, isolate y for each and compare with the direct variation equation.

Equation a

$y=\dfrac{4}{3}x-2$

This is not a direct variation equation as there is an addition of -2.

Equation b

$-x+y=0$

$\implies y=x$

This is a direct variation equation where the constant of variation is 1.

Equation c

$xy=8$

$\implies y=\dfrac{8}{x}$

This is not a direct variation equation as y is inversely proportional to x.

Equation d

$y=14$

This equation does not include the variable x, and so is therefore not a direct variation equation.
