Hey there!
To solve this problem, we will take a look at the FOIL Method.
<h3>
What is "FOIL"?</h3>
FOIL is a simple acronym that can be used to multiply binomials. It stands for:
F - Front
O - Outer
I - Inner
L - Last
See the image below for an example of how to use this in the given situation.
<h3>Apply</h3>
Front: <em>Multiply the two terms out in the front.</em>

Outer: <em>Multiply the two terms on the outsides.</em>

Inner: <em>Multiply the two terms on the insides.</em>

Last: <em>Multiply the two terms in the back.</em>

<h3>Add</h3>
Now, we add all of our answers from above:

<h3>Simplify</h3>

Given system of inequalities: y > 2/5(x) - 2 and y < -3x + 1.
We are given greater than (>) inequality symbol in first inequality.
For "only greater than inequality symbol" we would draw only a "dotted line".
Also in second inequality we have less than (<) inequality symbol.
For "only greater than inequality symbol" we would draw only a "dotted line".
In the shared graph, both the lines plotted are solid lines.
Therefore, correct option is B) The lines graphed should be dashed.
Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Each revolution has
radians, hence in one minute, the 120 revolutions will have a measure in radians of:
M = 120 x 2pi = 240pi = 753.98
Hence the angular velocity is of 753.98 radians per minute.

Answer: a is the # of elements in A but NOT B, that is A ONLY
b is the # of elements in B but NOT A, that is B only
N is the # of elements in the INTERSECTION of A and B
a + N = 99
b + N = 25
a + b + N = 123
Subtracting the first two equations: a - b = 74
Subtracting the last two equations: -a = -98
a = 98
So then a - b = 74 and a = 98
98 - b = 74
-b = -24
b = 24
a = 98, b = 24 and a + b + N = 123
98 + 24 + N = 123
122 + N = 123
N = 1
98 are in A only
24 are in B only , which is the answer to the question
1 is in both A and B
