The distance, y, Miranda travels while cross-country skiing, y, her distance traveled, varies directly with the amount of time, x, that she skis. Suppose Miranda skis 10 miles (the y coordinate) in 2 hours (the x coordinate).
A. What is the speed in miles per hour that Miranda is traveling?
B. Use your answer for (A) to write a direct linear variation equation relating this information.
C. How far will Miranda go in 3 hours?
D. If she travels 20 miles, how long did she ski? This one is worked out backward, be careful!
show your work
Using the principle of direct variation, the solution to the problem given are :
5 miles per hour d = 5t15 miles 4 hoursGiven the Parameters :
Distance = d
Amount of time = t
d α t ; d = kt
We can find k = constant of proportionality = speed of travel ;
d = 10 miles ; t = 2 hours
10 = 2k
k = 10/2
k = 5
Hence, speed = 5 miles per hour
B.) The direct linear variation expression becomes ;
d = 5t
C.) Distance traveled in 3 hours :
t = 3 hours
d = 5t
d = 5(3) = 15 miles
D. Time taken to travel a distance of 20 miles
d = 5t
20 = 5t
t = 20/5
t = 4 hours
Therefore, it will take 4 hours to travel a distance of 20 miles.

7x-24=6x-2
Answer:
[tex]7x - 24 = 6x - 2 \\ collecting \: like \: terms \: \\ 7x - 6x = - 2 + 24 \\ 1x = 22 \\ x = \frac{22}{1} \: \: or \: \: x = 22[/tex]
Answer:
x = 22
Here's how i got it ^u^
7x - 24 = 6x - 2
Step 1: Subtract 6x from both sides.
7x - 24 = 6x - 2
- 6x - 6x
x - 24 = - 2
Step 2: Add 24 to both sides.
x - 24 = - 2
+ 24 + 24
which TA-DA!!! it equals x = 22

The radius of circle A is r cm. The radius of circle B is twice the radius of circle A. What difference between the circumference of circle B and circle A (in cm)?
9514 1404 393
Answer:
2πr cm
Step-by-step explanation:
The circumference of a circle of radius r is ...
C = 2πr
For a radius of (r cm), the circumference is ...
A = 2π(r cm) = 2πr cm
For a radius of (2r cm), the circumference is ...
B = 2π(2r cm) = 4πr cm
Then the difference between the circumferences is ...
B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference

Write the equation of the graph in slope-intercept form (y = mx + b)
Answer:
y = -3x + 4
Step-by-step explanation:
To find the slope, use rise over run with two points. The first point (0,4) to the second point (-2,-2) is 6 units down and 2 units to the right, so you can set up a fraction to solve for the slope:
-6/2 = -3
To find the y-intercept,find the point where the x-value is 0. That point is (0,4),so the y-intercept is 4.
mx represents the slope, so mx is -3x and b is the y-intercept, so that value is 4.
Answer:
y = -3x + 4
Step-by-step explanation:
m = the slope (rise/run)
b = y-intercept
we can see that the rise is 6 (based on the two points) and the run is 2 (based on the labeled points)
- that means that m = 6/2 or m = 3
y = 0 when x = 4, so the y-intercept is 4, or b = 4
put it together!
y = 3x +b
BUT WAIT!!
- the line is decreasing which means that your equation should be negative, so put a negative symbol before 3x.
- why? the rise is decreasing!
final equation --------> y = -3x + 4
Write the equation of the line in slope-intercept form. The line is parallel to y+x=3 and passes through the point (−12, 0).
y = -x + 3
y = -(x + 12)
y = -x - 12

Tell whether the value is a solution of the inequality X=36; 3x<100
Answer:
x = 36 is not a solution
Step-by-step explanation:
3x<100
Let x = 36
3*36 < 100
108 < 100
This is not true so x = 36 is not a solution
Answer:
This inequality is False!
Step-by-step explanation:
3x < 100
3x36 < 100
108 < 100
Since 108 is greater than 100 this statement is not true. Hope this helps:)

Part 2: Graph the image of the figure using the transformation given. Don't forget to prime marks on your new image.
4. Reflection across the y-axis
Answer:
F' = (2 , -4)
G' = (-1 , -3)
H' = (4 , 0)
I' = (5 , -2)
Step-by-step explanation:
To get the coordinate points of a figure that is reflected across the y-axis, perform the following action to each point:
(x , y) → (-x , y)
Using this will give the points of F', G', H', and I'.
To find the new points, plug in the values into the formula:
F → F' = (-2 , -4) → (2 , -4)
G → G' = (1 , -3) → (-1 , -3)
H → H' = (-4 , 0) → (4 , 0)
I → I' = (-5 , -2) → (5 , -2)
To graph the new figure, plot the new points and connect them. At each point, remember to label them with the corresponding letter as well as the ' symbol.
