f(x)=3x+1, range x={4,5,6} --> domain is a set of values {13, 16, 19}
f(x)=x+10, for x={10,4,-6} domain is a set of {4, 14, 20}
Answer:
E + F = 2c² + 5c + 4
Step-by-step explanation:
![E = 6c^2 - 2c - 1 \\\\F = -4c^2 + 7c +5\\\\E + F = (6c^2 - 2 c -1) + ( -4c^2 + 7c +5)](https://tex.z-dn.net/?f=E%20%3D%206c%5E2%20-%202c%20-%201%20%5C%5C%5C%5CF%20%3D%20-4c%5E2%20%2B%207c%20%2B5%5C%5C%5C%5CE%20%2B%20F%20%3D%20%286c%5E2%20-%202%20c%20-1%29%20%2B%20%28%20-4c%5E2%20%2B%207c%20%2B5%29)

Answer:
y = 1300 - 100x
Step-by-step explanation:
Zachary purchased a computer for $1300
The first step is to calculate the purchase he paid after 2 months
= 1,300-1,100
= $200
Then the purchase after 1 month is
= $200/2
= $100 per month
The purchase made after 4 months is
= 1,100-900
= $200
The purchase after a month is
= $200/2
= $100 per month
Therefore the equation that models the balance y after x months is
= initial amount of payment plan - amount per month
y= 1,300 - 100x
Answer:
#3
Step-by-step explanation:
The perimeter is 10 try to draw these points on the graph and count the distance between each or you can just look at the coordinates and find the distance and then add length and width
