Answer:
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation y=-23x+5. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it us perpendicular to it. This means we will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
.
This is the equation of the line perpendicular to y=-23x+5 that crosses through (8,1).
Answer:
Use the graphing calculator to graph the system of equations and find the solution where x is the total hats sold and y is the total t-shirts sold.
x + y = 152,
8.5x + 12y = 1,656
How many hats were sold?
hats

Answer:
The 2 pound bag of gummy bears
Step-by-step explanation:
You do 1.5/4.35 which = 2.9 the 2.9 is $2.90 per pound
Then, you do 5.3/2 which = 2.6 this 2.6 is $2.60 per pound
$2.60 < $2.90 there for the 2 pound bag of gummy bears is the better deal
You follow the same steps as you would normally, but you can count how many units down it is, instead of how far up.
Here is how to solve it:
<span>Distance1 ÷ (plane velocity + wind velocity) = Distance2 ÷ (plane velocity - wind velocity)</span>800 / (180 + wv) = 640 / (180 - wv)
115,200 +640 wv = 144,000 - 800 wv
1,440 wv = 28,800
wind velocity = 20 mph
