PLEASE HELP 3x – 7 ≥ 4x + 2

sleet_krkn [62]

Hi there!

$\large\boxed{x \leq -9}$

3x - 7 ≥ 4x + 2

Subtract 3x from both sides:

3x - 3x - 7 ≥ 4x - 3x + 2

-7 ≥ x + 2

Subtract 2 from both sides:

-7 - 2 ≥ x + 2 - 2

-9 ≥ x

x ≤ -9

Match the following items.

Natalija [7]

The matchings are as follows:

1) 2=3 , 4 =5 (Given)

2) 1 =3 (vertical angles are equal)

3) 1 =2 (substitution)

4) VR=VR (Reflexive)

5) Triangle VSR congruent to Triangle VTR (ASA)

6) RS=RT CPCTE

The matchings are done above. The triangles are congruent as per ASA congruency as two angles and corresponding side is equal.

since 2 =3 and 1 = 3 we get 1=2

By CPCTE we have RS =RT
