Answer:
f(-6) = 3
Step-by-step explanation:
Simply plug in -6 as x
f(-6) = -(-6) - 3
f(-6) = 6 - 3
f(-6) = 3
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3
y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b
so ur equation is : y = 3x + 1....or 3x - y = -1
Based on the formula given for the model of the average cost of tuition and fees, the average cost of tuition in 2010 was $25,858.
<h3>What was the average cost of tuition at private colleges in 2010?</h3>
The base year is 2000 and x denotes the number of years after 2000.
The value of x for 2010 is therefore:
= 2010 - 2000
= 10 years
The average cost of tuition in 2010 is therefore:
= 26 (10)² + 814(10) + 15,118
= 2,600 + 8,140 + 15,118
= $25,858

Here a tip : if the top number is less then half of the bottom number, then it is less then 1/2.
less then 1/2 : 1/4, 1/5, 2/12
to be greater then 1, the top number must be bigger then the bottom number
greater then 1 : 6/5, 14/8, 11/10
