Answer:
period.
Step-by-step explanation:
Answer:
s = -2
Step-by-step explanation:
2(s+2)=4(s+2)
2s + 4 = 4s + 8
2s - 4s = 8 - 4
-2s + 4
s = -2
<span>Simplifying
u(x) = -2 + -2x + 7
Multiply u * x
ux = -2 + -2x + 7
Reorder the terms:
ux = -2 + 7 + -2x
Combine like terms: -2 + 7 = 5
ux = 5 + -2x
Solving
ux = 5 + -2x
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Divide each side by 'x'.
u = 5x-1 + -2
Simplifying
u = 5x-1 + -2
Reorder the terms:
u = -2 + 5x-1</span>
1a. It does say y is "less than 8", which means 7, 6, 5, 4, etc. So it should be y < 8, with the arrow going from 8 to the the left.
Everything else in 1 is correct.
For 2, you're just picking out which of the given numbers satisfy the inequality, for example
a. 14, 15, 16 are solutions. 13 is not because it is less than 14.
3. Same thing as 1
A=1/2 bh
40=1/2•20h
80=20h
4=h
