Answer:
y = (-3/2) x + 3
Step-by-step explanation:
The line passes through (0, 3) and (2, 0)
Slope = (0 - 3)/(2 - 0) = -3/2
Let y = (-3/2) x + b
Use (0, 3) to get b:
3 = (-3/2)*0 + b, so b = 3
Then y = (-3/2) x + 3

The total cost of 7 shirts and 5 pairs of pants is $517. The total cost of a shirt and a pair of pants is $89. How much does a pair of pants cost?
Answers
Answer:
pair of pants = $53
Step-by-step explanation:
s = shirts
p = pair of pants
eq = equation
eq 1: 7s + 5p = 517
eq 2: s + p = 89
multiply the equation 2 by 7
eq 3: 7s + 7p = 623
negate equation 1 and add it to the eq 3
7s + 7p = 623
+ -7s - 5p = -517
2p = 106
p = 53

Answer:
see the attachments for the graph, and a spreadsheet with midpoints and slopes
Step-by-step explanation:
We are given the coordinates of the vertices of a triangle, and asked to find the parameters of the perpendicular bisectors of the sides of the triangle. The perpendicular bisectors are to be plotted on the graph.
Given:Coordinates A(1, 6), B(5, 4), C(5, -2)
__
Find:a) Graph and label the triangle
b) Find the midpoint of each side of the triangle
c) Find the slope of each side of the triangle
d) Find the slope of each perpendicular bisector
e) Use the midpoint and the perpendicular slope to accurately draw each perpendicular bisector on the triangle
__
Solution:a)See the attached graph for shaded triangle ABC.
__
b)The midpoint (M) of a segment AB will be ...
M = (A+B)/2
For example, the midpoint of segment AB is ...
D = ((1, 6) +(5, 4))/2 = (1+5, 6+4)/2 = (6, 10)/2 = (3, 5)
This repetitive arithmetic is carried out in the spreadsheet shown in the second attachment. The midpoints are ...
D(3, 5) is midpoint of AB
E(5, 1) is midpoint of BC
F(3, 2) is midpoint of CA
__
c)The slope of a segment is found using the slope formula (or by counting grid squares). That formula is ...
m = (y2 -y1)/(x2 -x1)
For segment AB, this is ...
mAB = (4 -6)/(5 -1) = -2/4 = -1/2
The other slopes are calculated similarly in the spreadsheet. When the denominator is zero (a vertical line), the slope is "undefined."
mBC = undefined
mCA = -2
__
d)The slope of the perpendicular line is the opposite reciprocal of the slope of the segment.
m⟂AB = -1/(-1/2) = 2
m⟂BC = 0 . . . . . a horizontal line has 0 slope
m⟂CA = -1/-2 = 1/2
__
e)The perpendicular bisectors of each of the sides of the triangle are shown in the first attachment. As the lesson title indicates, their point of concurrency is G(1, 1), the circumcenter of the triangle.

Based on past concerts, a band predicts selling 600-10p concert tickets when each ticket is sold at p dollars. Complete the table to find out how many concert tickets the band expects to sell and what revenues it expects to receive at the given ticket prices.
Answers
The formula for the number of tickets sold, 600 - 10·p, gives the
revenue at a given number of tickets as 600·p - 10·p².
How can the given table be completed?The number of tickets sold = 600 - 10·p
The revenue = Ticket price × (600 - 10·p)
The completed table is presented as follows;
[tex]\begin{array}{c|c|c|}Ticket \ price \ (dollars)&Number \ of \ tickets&Revenue \ (dollars)\\10&600 - 10 \times 10 = 500&10 \times 500 = 5000\\15&600 - 10 \times 15 = 450&10\times 450 = 4500\\20&600 - 10 \times 20 = 400&10 \times 400 = 4000\\30&600 - 10 \times 30 = 300&10 \times 300 = 3000\\35&600 - 10 \times 35 = 250&10 \times 250 = 2500\\45&600 - 10 \times 45 = 150&10 \times 150 = 1500\\50&600 - 10 \times 50 = 100&10 \times 100 = 1000\\60&600 - 10 \times 60 =0&10 \times 0 = 0\\p\end{array}\right][/tex]
The general formula for the revenue, given a number of tickets sold of 600 - 10·p is therefore;
The revenue = p × (600 - 10·p) = 600·p - 10·p²Therefore, when the ticket sold is p, we have;
Number of ticket sold = 600 - 10·pRevenue = 600·p - 10·p²Learn more about functions here:

The completed table is as follows:
Ticket price (dollars) Number of tickets Revenue (dollars)
10 500 5000
15 450 6750
20 400 8000
30 300 9000
35 250 8750
45 150 6750
50 100 5000
To complete the table and find out the number of concert tickets the band expects to sell and the revenue it expects to receive at the given ticket prices.
we need to use the provided information that the band predicts selling 600 - 10p concert tickets when each ticket is sold at p dollars.
The number of tickets sold = 600 - 10·p
The revenue = Ticket price × (600 - 10·p)
By plugging the value of ticket price we find the number of tickers and revenue.
If ticket price is 10.
Then plug in p =10 to find the number of tickets sold in the equation.
The number of tickets sold = 600 - 10·p
=600-10(10)
=500
Revenue = 10(600-10(10))
=10(500)
=5000
Similarly we fill the table by using this format.

A large company put out an advertisement in a magazine for a job opening. The first day the magazine was published the company got 70 responses, but the responses were declining by 10% each day. Assuming the pattern continued, how many total responses would the company get over the course of the first 23 days after the magazine was published, to the nearest whole number?
Answers
Answer:
638
Step-by-step explanation:
The total number of responses is the value of a geometric series with first term 70 and common ratio 1-10% = 0.90. That sum is given by the formula ...
Sn = a1·(1 -r^n)/(1 -r)
where r is the common ratio, n is the number of terms, and a1 is the first term.
The sum of n=23 terms of the series with a1=70 and r=0.9 is ...
S23 = 70·(1 -0.9^23)/(1 -0.9) = 700(1 -0.9^23) ≈ 638
The model predicts 638 total responses over the first 23 days.

what is: a + 1/10=5/10 ? pls dont delete this its school work.
Answers
Answer:
a = 2/5
Step-by-step explanation:
a + 1/10 = 5/10
Subtract 1/10 from both sides of the equation.
a + 1/10 = 5/10
-1/10 -1/10
a = 4/10
This answer is not incorrect but we usually need to simplify it if possible.
4/10 can be reduced to 2/5.
a = 2/5
Answer:
a=2/5
Step-by-step explanation:
To solve this, we first need to isolate the a so we can solve from there
First, we subtract 1/10. But whatever we do to one side we have to do to the other side. So when we subtract 1/10 from the left side we cancel it out and we subtract 1/10 from the right side so 5/10-1/10
So our equation becomes…
a=5/10-1/10
We can simplify this to…
a=4/10
4/10 is equal to 2/5
So that is our final answer
Now since we have nothing else to do that is our final answer
