Answer:
D) x > –7
Step-by-step explanation:
–3x – 6 < 15
Add 6 to each side
–3x – 6+6 < 15+6
-3x < 21
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 21/-3
x >-7
C=2(pi)r
d=2r
d/2=r
5=2r
5/2=r
2.5 = r
c= 2 22 25

Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
7x - 2y = - 20 → (1)
9x + 4y = - 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the term in y
14x - 4y = - 40 → (3)
Add (2) and (3) term by term to eliminate the term in y
23x = - 46 ( divide both sides by 23 )
x = - 2
Substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (2)
9(- 2) + 4y = - 6
- 18 + 4y = - 6 ( add 18 to both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (- 2, 3 )
