7x-2=5x+14<br> X=?<br> (step by step needed)
prisoha [69]

Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

  • 7x-2-5x=5x+14-5x
  • 2x-2=14  

Step 2: Add 2 to both sides.

  • 2x-2+2=14+2
  • 2x=16

Step 3: Divide both sides by 2.

  • 2x/2=16/2
  • x=8

Step 4: Check if solution is correct.

  • 7(8)-2=5(8)+14
  • 56-2=40+14
  • 54=54

Therefore, x = 8.

Which graph represents the following system of inequalities?<br> y &gt; 2x - 5<br> y &lt;-3x
NARA [144]

Answer:

The graph i the attached figure

Step-by-step explanation:

we have

y > 2x-5 ----> inequality A

The solution of the inequality A is the shaded area above the dotted line y=2x-5

The slope of the dotted line is positive

The x- intercept of the dotted line is the point (2.5,0)

The y- intercept of the dotted line is the point (0,-5)

y < -3x -----> inequality B

The solution of the inequality B is the shaded area below the dotted line y=-3x

The slope of the dotted line is negative

The x- intercept of the dotted line is the point (0,0)

The y- intercept of the dotted line is the point (0,0)

The solution of the system of inequalities is the shaded area between the two dotted lines

see the attached figure
