What is the solution for the inequality |-5x+2|<7

Answers

i'm just gonna try my best.
it will be -5x+2=7
let's ignore the less than sign, so it will be -5x=7-2
   ; -5x=5
   ; x=-1
If the question asks you to graph it, you will graph -1 less than 7 or -17
i'm sorry that i cant find the less than sign
|-5x + 2| < 7
|-5x + 2| < ±7
|-5x + 2| < 7    or    |-5x + 2| < -7
  -5x + 2 < 7      or    -5x + 2 < -7
         - 2  - 2                    - 2   - 2
        -5x < 5       or         -5x < -9
         -5    -5                    -5    - 5
           x < -1        or        x < 1⁴/₅

Which ondered pair is the solution to this system of equations? y=x+4 x+y=2 (1) (1,5) (2) (0,2) (3)(-1,3) (4)(-4,0)

Answers

Solve the following system:

{y = x + 4 | (equation 1)

y + x = 2 | (equation 2)

Express the system in standard form:

{-x + y = 4 | (equation 1)

x + y = 2 | (equation 2)

Add equation 1 to equation 2:

{-x + y = 4 | (equation 1)

0 x + 2 y = 6 | (equation 2)

Divide equation 2 by 2:

{-x + y = 4 | (equation 1)

0 x + y = 3 | (equation 2)

Subtract equation 2 from equation 1:

{-x + 0 y = 1 | (equation 1)

0 x + y = 3 | (equation 2)

Multiply equation 1 by -1:

{x + 0 y = -1 | (equation 1)

0 x + y = 3 | (equation 2)

Answer: x = -1 y = 3
