I think with the kinds of mixture problems, it's really helpful to make a table.
The equations you actually need are
and
. Since I was so close, I went ahead and just solved it anyway. You can see my setup on the attached image.
Answer:
<h3>p = 1</h3>
Step-by-step explanation:
Answer:
x ≥ 2 or x ≤ -2
Step-by-step explanation:
|2x+1|≥5
There is a positive and negative solution. When we take the negative solution we flip the inequality.
2x+1 ≥5 or 2x+1 ≤-5
Subtract 1 from each side
2x+1-1 ≥5-1 2x+1-1 ≤-5-1
2x ≥ 4 2x ≤- 4
Divide by 2
2x/2 ≥ 4/2 2x/2 ≤- 4/2
x ≥ 2 or x ≤ -2
Answer:
-14m - 18
Step-by-step explanation:
Hi there!
To find the answer, we will first have to merge the expressions.
-18m - 4 + 4m - 14
To simplify this, we have to combine like terms.
-18m and 4m can be added together to create -14m
-4 and -14 can be added together to make -18.
Now that our terms are simplified, the expression becomes -14m - 18.
Hope this helped!
Step-by-step explanation:
arccos(sin(5π/4))
= arccos(sin(-π/4))
= arccos(-√2/2)
= 3π/4.
