First move +5 to to the other side.
-7x=-16-5
-7x=-21
Then after this devide both sides by negative seven.
X=3
2,7, and 6 are all 70 degrees. 1,4,5, and 8 are all 110 degress

Answer:
M₅ = 1.6570
Step-by-step explanation:
The basic idea is to find the function values at x ∈ {1.1, 1.3, 1.5, 1.7, 1.9}, add those values, and multiply the result by 1/5. Those x-values are the midpoints of intervals 0.2 units wide, between x = 1 and x = 2. The width 0.2 is the total interval width (2-1=1) divided by n = 5.
The calculation and results are shown in the attachment. Rounded to 4 decimal places, the integral is ...
M₅ = 1.6570
__
The actual integral is about 1.6574, so this is pretty close.
<h3>
Answer: They're all the same</h3>
====================================================
Reason:
means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say
The parenthesis are optional, but I find they're handy to count the '2's easier.
----------------
Now notice that
So,
The last step is possible because we have two copies of multiplied together.
This shows that choice C is equivalent to A and B.
-------------------
Lastly,
The jump to the last step is possible because we have three copies of multiplied together.
This shows choice D is equivalent to the others.
All four expressions are the same.
They represent different ways to say the same number. That number being 64.

Answer:
23
Step-by-step explanation:
Put 8 in the formula and do the arithmetic.
A8 = 2·8 +7 = 16 +7
A8 = 23
