a. The constant of proportionality is k = 2
b. If Micah saves $150, his parents will give him $300
<h2>
Explanation:</h2>
<h3>PART A.</h3>
From mathematics, we know that
varies directly as
or
is directly proportional to
if and only if:
for some nonzero constant
.
Here we know some facts:
- For every $5 that Micah saves, his parents give him $10.
In other words:
Let y be the money his parents give him.
Let x be the money that Micah saves.

So,<em> the constant of proportionality is k = 2</em>
<h3>
PART B.</h3>
In this case, we know that Micah saves $150. So we need to find the amount of his parents will give him. So what we know here is the value of x, because x represents the amount of money Micah saves. Therefore, by knowing x and k, we can calculate the value of y, which is the amount of money his parents will give him. Hence:

Finally, <em>if Micah saves $150, his parents will give him 300$</em>

Y=.05x +4100
Y=.05(3)+4100
Y=.15+4100
Y=4100.15
GCF is the Greatest Common Factor. It would be the largest number that can divide evenly into all the numbers you need to find the GCF in.
exapmple GCF for 12 and 16
12: 1, 2, 3, 4, 6, 12
16: 1, 2, 4, 8, 16
the largest common number is 4, so 4 is the GCF of 12 & 16
LCM = Least Common Multiple is the smallest number ( other than zero) that is a multiple of both
LCM of 3 and 5
3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20
the first common number is 15, so this is the LCM of 3 & 5

Answer:
Domain = [-5, -2) U (1, 3)
Range = (-3, 4]
Step-by-step explanation:
Domain is the x values
Domain = [-5, -2) U (1, 3)
Range is the y values
Range = (-3, 4]
