Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.

Answer:
slope = -3/4
using the formula
y -y1 = m(x -x1)
y -1 = -3/4(x -(-8))
y -1 = -3/4(x +8)
cross multiply
4(y -1) = -3(x +8)
4y -4 = -3x -24
4y = -3x -24 +4
4y = -3x -20
divide both sides by 4
y = -3/4 x -5 (equation of the line)
Answer:
<h2>
$30.24!</h2>
Step-by-step explanation:
Find the discounted price by setting up an equation
40-.3(40) AKA 30% of the original price is being taken off of the original price
Evaluate
40-12
$28 = discounted price
Sales tax is based on the reduced/discounted price* remember this
OF= multiplication (in this scenario)
.08x28
$2.24= sales tax
Add tax with discounted price
28+2.24=
<h2>
$30.24!</h2>
