a) The variable in the inequality is <u>x.</u>
b) The inequality symbol needed <u>< ( or >)</u>
c) The constant is <u>8.</u>
d) The inequality is <u>f(x)<8x .</u>
Step-by-step explanation:
Given,
The person can make less than $8 per hour
To find the correct inequality for this situation.
Let us take,
The person works for x hours.
If the total income of the person for x hours is f(x)
Then, the inequality will be
f(x)<8x
Answer:
<m is equal to the measure of <Z

Hope this helps!!
Please tell me if I have made a mistake!!
I enjoy learning form them:)
1)
LHS = cot(a/2) - tan(a/2)
= (1 - tan^2(a/2))/tan(a/2)
= (2-sec^2(a/2))/tan(a/2)
= 2cot(a/2) - cosec(a/2)sec(a/2)
= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))
= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)
= 2[(1+cos(a) -1)/sin(a)]
=2cot a
= RHS
2.
LHS = cot(b/2) + tan(b/2)
= [1 + tan^2(b/2)]/tan(b/2)
= sec^2(b/2)/tan(b/2)
= 1/sin(b/2)cos(b/2)
using product to sums
= 2/sin(b)
= 2cosec(b)
= RHS
