Answers:
Horizontal Line: y = 5
Vertical Line: x = 8
=================================================
Explanation:
All horizontal lines are of the form y = k, for some constant k. We want the horizontal line to pass through (8,5), meaning every point on this horizontal line must have y coordinate 5. Therefore, y = 5 is the equation of the horizontal line. Two such points on this line are (1, 5) and (8, 5). All that matters is the y coordinate is 5. The x coordinate can be anything you want. The slope of any horizontal line is 0.
Flipping things around, all vertical lines will have the x coordinate of each point be the same value. Draw a vertical line through (8,5) and note how each point has x coordinate of 8. Two such points are (8,1) and (8,5). Therefore, the equation of the vertical line is x = 8. The y coordinate can be any value you want. The slope of any vertical line is undefined. Unlike the horizontal line, we cannot write this equation in slope intercept form (namely because the slope isn't defined).
Bradley had 25 baseball cards in his collection. He receives x number of baseball cards for his birthday.
Enter an equation that represents the total number of baseball cards, y, Bradley now has in his collection.
Answer:
25 + x = y
Step-by-step explanation:
He gets x(unknown amount of cards) so add that, and the total will equal y.

Can someone help me I don't know what n represents
Answer:
n=7
Step-by-step explanation:
6(n-3) - 2n=10
Distribute
6n - 18 -2n = 10
Combine like terms
4n -18 = 10
Add 18 to each side
4n-18+18 = 10+18
4n = 28
Divide by 4
4n/4 = 28/4
n = 7
Solve the solution by substitution.
Y= —5x + 13
-6x + 6y = 6
Show/ explain your work
Answer:
the solution is (2, 3)
Step-by-step explanation:
Make this work easier by reducing the second equation:
-x + y = 1, or y = x + 1
Substititing x + 1 for y in the first equation, we get:
x + 1 = -5x + 13, or (after combining like terms):
6x = 12
Then x = 2, and bercause y = x + 1 (see above), y = 2 + 1 = 3
Then the solution is (2, 3)
f(x) = 3x + 2

What transformations are applied to the graph of the function f(x)=10^x to produce the function g(x)=3(10)^x-2
A.) a vertical dilation by a factor of 3 and a horizontal shift to the right 2 units
B.) a vertical dilation by a factor of 1/3 and a horizontal shift to the right 2 units
C.) a vertical dilation by a factor of 1/3 and a vertical shift down 2 units
D.) a vertical dilation by a factor of 3 and a vertical shift down 2 units
Answer:
D) A vertical dilation by a factor of 3 and a vertical shift down 2 unitsStep-by-step explanation:
Given
f(x)=10^xg(x)=3(10)^x - 2We see that:
g(x) = 3f(x) - 2This is a vertical stretch by a factor of 3 and translation down 2 units
Correct choice is D

Brewster collected 100 pounds of aluminum cans to recycle. He plans to
collect an additional 25 pounds each week. Write and graph the equation
for the total pounds, P, of aluminum cans after w weeks. *
Answer:
Slope represents that the weight of can increased by 25 pounds each week. Y-intercept represents initial weight of cans, i.e., 100 pounds.
The time taken by Rufus to collect 400 pounds of aluminum cans is 12 weeks.
Step-by-step explanation:
It is given that Rufus collected 100 pounds of aluminum cans to recycle. He plans to collect and additional 25 pounds each week.
It means initial weight of cans = 100 pounds
Additional weight of cans = 25 pounds each week
Let W be the number of week.
The equation for the total pounds P of aluminum cans after W weeks is
.... (1)
The slope intercept form of a line is
.... (2)
where, m is slope and b is y-intercept.
From (1) and (2) we get
It means slope and y-intercept are 25 and 100 respectively.
Slope represents that the weight of can increased by 25 pounds each week. Y-intercept represents initial weight of cans, i.e., 100 pounds.
We need to find the time taken by Rufus to collect 400 pounds of aluminum cans.
Substitute P =400 in equation (1).
Subtract 100 from both sides.
Divide both sides by 25.
Therefore, the time taken by Rufus to collect 400 pounds of aluminum cans is 12 weeks.

A bakery sells cakes, cookies, and pastries. They wonder if customers are equally likely to buy each product
They take a sample of 200 recent purchases and record what was purchased (they are willing to treat this as
a random sample). Here are the results:
Product
Observed purchases
Cakes
65
Cookies Pastries
68
67
They want to perform a x' goodness-of-fit test to determine if these results suggest that one type of
product is more popular than the others.
What is the expected count of cake purchases?
You may round your answer to the nearest hundredth.
Expected:
Answer: The expected count of cake purchases is 66.67 (rounded to the hundreths).
Step-by-step explanation: Hypothesis the bakery is trying to find is if customers are equally likely to buy each product and since the sample is 200, we would have to equally split that between the 3 categories, so the expected counts for Cakes, cookies, and pastries would all be 66.67 (rounded to the hundreths).
The expected count of cake purchases would be 66.67 (rounded to the hundredths).
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The results are given as:
Product Observed purchases
Cakes 65
Cookies 68
Pastries 67
To find if customers are equally likely to buy each product and since the sample is 200,
we would have to equally split that between the 3 categories,
The expected count of cake purchases = 200/3
= 66.67
Thus, the expected counts for Cakes, cookies, and pastries would be 66.67 (rounded to the hundredths).
