Answer:
no solution
Step-by-step explanation:
3(x – 2) + 1 ≥ x + 2(x + 2).
Distribute
3x – 6 + 1 ≥ x + 2x + 4
Combine like terms
3x -5 ≥ 3x +4
Subtract 3x from each side
-5 ≥ 4
This is never true so there is no solution
Answer:
x = 5
Step-by-step explanation:
Because the sides shown are parallel, the triangles are similar. That means the lengths of their sides and segments of sides are proportional.
x/(x + 10) = 10/30
x/(x + 10) = 1/3
3x = x + 10
2x = 10
x = 5
Step-by-step explanation:
f(10)=10
f(-2)=-2
f(a)=a
f(a+b)=a+b
g(10)=5×10-12=3
g(-2)=5×(-2)-12=-10-12=-22
g(a)=5×a-12=5a-12
g(a+b)=5×(a+b)-12=5a+5b-12
h(10)=(10)^2 +4(10)-7=100+40-7=133
h(-2)=(-2)^2 +4(-2)-7=4-8-7=-11
h(a)=a^2 +4a -7
h(a+b)=(a+b)^2 +4a+4b-7=a^2+2ab+b^2+4b-7
