You need to isolate the "x" in both inequalities
5x + 7 ≤ -3 Subtract 7 on both sides
5x ≤ -10 Divide 5 on both sides
x ≤ -2
3x - 4 ≥ 11 Add 4 on both sides
3x ≥ 15 Divide 3 on both sides
x ≥ 5
This is your simplified inequalities:
5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A
Answer:
the width if 16 feet the length is 32
Step-by-step explanation:
For the given equation ⇒⇒⇒

and the given range 0 ≤ x ≤ π
We should note that the zeros of the denominator will be at
cos x = 0
∴

So, the given equation is undefined at π/2
So, <span>the students error is the division by zero.

See the attached figure which represents the graph of the given equation and we can see it is undefined at π/2

It’s nine because 3*8 equals 24 and 3*3 =9
