Answer:
B
Step-by-step explanation:
Equation for a line is y = mx + b where m is the slope and b is the y intercept.
First, we see that the y intercept is 60.
Second, we see that for every 10 units y decreases, x increases by 5. This gives us a slope of -2 because (-10/5)=-2
If we plug our values into the equation of a line we get
y=-2x+60
Is (-2, 1) a solution to the system
x -y = -3
y = -2x + 5
Answer:
No, I believe the solution is (2/3, 11/3)

Chloe makes a long distance call from a pay phone, the first minute of a call cost $2.30. After that, each additional minute is $0.20. How many minutes can Chloe talk for $4.30?
Answer:
The number of minutes is 10minutes
Step-by-step explanation:
Step one:
Given that the first minute of a call cost $2.30 and
each additional minute is $0.20.
let the number of minutes be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that y=4.3, we can solve for the totals cost as
by substituting we have
4.3=0.2x+2.3
4.3-2.3=0.2x
2=0.2x
x=2/0.2
x=10
The number of minutes is 10minutes

Find the slope of AB: A(-2, 5) and B(6.-1)
Answer:
Step-by-step explanation:
y2- y1/x2-x1
-1-5/6-2
-6/8
The required slope of AB is -3/4 which passes through points A(-2, 5) and B(6.-1).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
To determine the slope of AB: A(-2, 5) and B(6.-1)
Given,
We have been given that two points are A(-2, 5) and B(6.-1)
Let
x₁ = -2, y₁ = 5
x₂ = 6, y₂ = -1
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in the formula
The slope of AB = (-1 - 5)/(6 - (-2))
The slope of AB = (-6)/(6 + 2)
The slope of AB = -6/8
Therefore, the required slope of AB is -3/4.

There are 3 counselors assigned to each group of 24 campers, how many campers would there be if there was 9 counselors
Answer:
72 campers
Step-by-step explanation:
To solve this problem, first we know that there are 3 counselors for every 24 campers. To get from 3 campers to 9 campers, you would need to multiply 3 by 3. If you do this with the campers, you would also need to multiply the counselors (24) by 3 as well. 24 times 3 = 72.
So, if there are 9 counselors, there would need to be 72 campers.

A rocket is 1.5miles above the earth in 20 seconds and is 8 miles above the earth in 2 minutes. What is the rockets rate of change in miles per seconds
Given:
A rocket is 1.5 miles above the earth in 20 seconds.
It is 8 miles above the earth in 2 minutes.
To find:
The rockets rate of change in miles per seconds.
Solution:
Let y be the height above the earth after x seconds.
A rocket is 1.5 miles above the earth in 20 seconds. So, the point is (20,1.5).
It is 8 miles above the earth in 2 minutes.
1 minute = 60 seconds
2 minutes = 120 seconds
So, the point is (120,8).
The rockets rate of change in miles per seconds is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{8-1.5}{120-20}[/tex]
[tex]m=\dfrac{6.5}{100}[/tex]
[tex]m=0.065[/tex]
Therefore, the rockets rate of change is 0.065 miles per seconds .
The quotient below is shown without the decimal point. Use number sense to place the decimal point correctly.
340.1 ÷ 9.5 = 358
Answer:
35.8
Step-by-step explanation:
[tex]\frac{340.1}{9.5}[/tex] = 358
We know that our answer can never be greater than 358 since the dividend
is 340.1 and the divisor is 9.5;
Also,
Both values are to one decimal places and we can use this to solve the problem;
9 can divide 340 in about 37 place with a remainder of 7,
So, it is appropriate to make the solution 35.8

Solve each equation by factoring. r² - 4r + 4 = 0
Answer:
The answer would be r = 2
Step-by-step explanation:
Answer:
r=2
Step-by-step explanation:
r² - 4r + 4 = 0
r^2-(2+2)r+4=0
r^2-2r-2r+4=0
r(r-2)-2(r-2)=0
(r-2)(r-2)=0
r=2,2
help please ahahah i hate this sm i really need help
Answer:
-7/6
Step-by-step explanation:
- take two values of x and their corresponding two values of y
- use the slope formula ( y2 - y1 )/( x2 - x1 )
- i used x values 4 and 10 but you can use any
( -6 - (-13) ) / ( 4 - 10 ) = -7/6

The post office sold 39-cent
commemorative stamps in sheets
of 25 stamps. What was the price
for the sheet of stamps?
Answer: $9.75.
Step-by-step explanation:
Given: Cost per stamp = 39 cents
since 1 dollar = 100 cent , so 1 cent = 0.01 dollar
So, Cost per stamp = $0.39
Total stamps = 25
Cost of 25 stamps = (Cost per stamp) x (Cost per stamp)
=$0.39 x 25
= $9.75
Hence, the price for the sheet of stamps = $9.75.
