Answer:
d=cπ
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Part a) ![y=5x+100](https://tex.z-dn.net/?f=y%3D5x%2B100)
Part b) The cost to take classes every weekend (Saturday and Sunday) during the month of January is $140
Step-by-step explanation:
Part a)
Let
x ----> the number of classes
y ----> the total cost
we know that
The equation of the line in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem
The slope is equal to ![m=\$5\ per\ class](https://tex.z-dn.net/?f=m%3D%5C%245%5C%20per%5C%20class)
The y-intercept is
---> annual fee
substitute
![y=5x+100](https://tex.z-dn.net/?f=y%3D5x%2B100)
Part b) Use the equation from above and find out how much it would cost to take classes every weekend (Saturday and Sunday) during the month of January
we know that
During the month of January 2020 we have 8 classes (4 Saturday and 4 Sunday)
so
For x=8
substitute in the linear equation
![y=5(8)+100](https://tex.z-dn.net/?f=y%3D5%288%29%2B100)
![y=\$140](https://tex.z-dn.net/?f=y%3D%5C%24140)
therefore
The cost to take classes every weekend (Saturday and Sunday) during the month of January is $140
Seventy thousand, seven hundred square miles. hope this helps
This simplified is 126x so that is equivalent to this expression
Answer: 289 is a semi-prime number that is created by doing 17 times 17. 17 is a prime number though. hope this helps.
