Answer:
The slope is 2.
Step-by-step explanation:
Slope formula is rise/run. So in other words, it is y2-y1/x2-x1. In this case it would be 12-8/3-1. That equals 4/2. You need to simplify that by dividing both 4 and 2 by 2. So, that gives you 2/1. Whenever you have a number over 1 that is the same as saying just the numerator. So the slope would be 2.

Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor.
Answer:
C
Step-by-step explanation:
The similarity statement is correct. Because they are similar, AB is equal to EF, so to find x, you do x-2=2.2. Solve that and you get x=0.2
Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. Write an equation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.
Answer:
h = 42y
Step-by-step explanation:
The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has.
h = ky
Where,
h = the number of hats she can knit
y = amount of yarn she has(yards)
k = constant of people = 42
Eequation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.
h = 42y
The observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground. The express elevator travels nonstop from the ground floor to the observatory on the top floor at a rate represented by the equation y=30x, where y is the height, in feet, and x is the number of seconds.
Answer:
Step-by-step explanation:
Given the rate at which the elevator travels modeled by the expression;
y = 30x where y is the height, in feet, and x is the number of seconds.
If the observatory in the John Hancock Center in Chicago is located in the top floor, 900 feet above the ground, we can calculate the time taken to reach the top floor by substituting y = 900 into the equation and solve for x as shown;
y = 30x
900 = 30x
Rearrange
30x = 900
Divide both sides by 30
30x/30 = 900/30
x = 30
Hence it takes 30seconds for the elevator to reach the top floor

1. 88
2. 5 1/2
3. -88
4. -5 1/2
Answer:
My answer came out to -22.
Step-by-step explanation:
Start multiplying from left to right:
Two negatives multiplied are positive:
-2.2·(-2)=4.4
A negative and a positive multiplied equal a negative:
4.4·(-1)=-4.4
-4.4·5=-22
2x+2=4+1x
and we are solving for X
Answer:
the answer is x = 2
Step-by-step explanation:
2x+2=4+1x
(2x-1x)+2= 4 +(1x-1x)
1x+2=4
1x(2-2)=(4-2
1x=2
2/1=x
x=2
Answer: X=2

The graph shows the data for the time it takes Jerome to bike to school, based on his average biking speed for that trip. Which sentence describes the association?
A.The speed he bikes at affects the time it take him to get to school, but it is unclear if the time increases or decreases.
B. As the average speed increases, the time he takes to get to school decreases.
C. The speed he bikes at does not affect the time it takes him to get to school.
D. As the average speed increases, so does the time he takes to get to school.
Answer:
B: As the average speed increases, the time he takes to get to school decreases.
Step-by-step explanation:
On the graph, it showed that the plotted points are decreasing as the average speed is increasing. Also, I took the test and B was the correct answer.

Answer:
2.25 miles
Step-by-step explanation:
If she can walk 3/4 of a mile in 20 minutes you need to multiply 3/4 by 3 because 20 times 3 is 60 and there is 60 minutes in a hour

What is the equation of the line that goes through the points 2,9 and 3,1
The equation of the line that goes through the given points is y = -8x + 25.
Given the following points:
Points on the x-axis = (2, 3)Points on the y-axis = (9, 1)To determine the equation of the line that goes through the given points:
First of all, we would determine the slope of this line by using the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the points into the formula, we have;
[tex]Slope, \;m = \frac{1 - 9}{3 - 2}\\\\Slope, \;m = \frac{-8}{1}\\\\[/tex]
Slope, m = -8
Now, we can determine the equation of the line by using this formula:
[tex]y-y_1 =m(x-x_1)\\\\y-9=-8(x-2)\\\\y-9=-8x+16\\\\y=-8x+16+9[/tex]
y = -8x + 25

Help me with (-6,-7);y=-4x+1
Answer: y=-4x-31
Step-by-step explanation:
To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.
-7=-4(-6)+b [multiply]
-7=24+b [subtract both sides by 24]
b=-31

Answer:
r = -189
