Answer:
j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
The easiest way to find slope is to do rise/run. In this case, you rise from point (0,-3), and 'run' to point (-2,-2). The slope would be -1/2 because you are 'running' to the left, which is negative.
The value of the product expression given as product of (2i) and (5+3i) is 10i -6
<h3>How to determine the product?</h3>
The product expression is given as:
product of (2i) and (5+3i)
Rewrite the expression as:
(2i) * (5+3i)
Open the brackets
(2i) * (5+3i) = 10i + 6i^2
Evaluate
(2i) * (5+3i) = 10i + 6(-1)
This gives
(2i) * (5+3i) = 10i -6
Hence, the value of the product expression given as product of (2i) and (5+3i) is 10i -6

Calculation for plan A:
Let numbe of months = x
Given that $10 is the monthly fee.
Given that $150 is the joining fee.
Then cost equation for plan A is given by:
A=10x+150
Calculation for plan B:
Let numbe of months = x
Given that $30 is the monthly fee.
Given that $50 is the joining fee.
Then cost equation for plan B is given by:
B=30x+50
Now we have to find on what month will the cumulative costs of the plans be equal.
So we will just set both equations equal to each other
10x+150=30x+50
150-50=30x-10x
100=20x
5=x
Hence it will take 5 months to make cost of both plans equal.
To find the total cost plug x=5 into any of above equations:
A=10x+150=10*5+150=50+150=200
Hence final cost will be $200.
