Tell whether x and y are in a proportional relationship. If so, find the unit rate. Let y be the temperature x hours after midnight. The temperature is 60∘F at midnight and decreases 2∘F every 1/2 hour
Answer:
x and y are not in a proportional relationship
Step-by-step explanation:
The temperature is 60 F at midnight, and decreases 2 F every 1/2 hour, x represents hours, y represents temperature.
Plot (0, 60) , (0.5, 58) , and (1, 56)
Draw a line through the prints.
The graph is a line that does not pass through he origin.
SO, x and y are not in a proportional relationship.

Answer:
[tex]m=3[/tex]
Step-by-step explanation:
[tex]6m+5-3m=7(m-1)[/tex]
Combine like terms
[tex]3m+5=7(m-1)[/tex]
Distribute the 7
[tex]3m+5=7m-7[/tex]
Subtract 3m from each side
[tex]4m-7=5[/tex]
Add 7 to each side
[tex]4m=12[/tex]
Divide by 4
[tex]m=3[/tex]
20 points each!!! Heather has 2 less than 5 times the amount of shoes that Donna has, Gina has 1 more than 2 times
amount of shoes that Donna has. Let x represents how many shoe Donna has.
a. Write an expression that represents how many more pairs of shoes Heather has than Gina.
b. Simplify the expression:
c. How many more pairs of shoes does Heather have is Donna has 14 pairs of shoes?
Answer:
A. (5x - 2) - (2x +1)
B. x -1
C. 68
Step-by-step explanation:
Heather = 5 times Donna -2 H = 5D - 2
Gina = 2 times Donna + 1 G = 2D + 1
Plug in D for X and you get
H = 5x -2
G = 2x + 1
If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.
(5x - 2) - (2x +1)
Now to simplify it, you just combine all the like terms.
5x - 2 - 2x -1 = 3x - 3 and then you can simply this further by dividing all terms by 3. x - 1
To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation. 5 (14) -2 = 70 - 2 = 68

Step-by-step explanation:
figure pqsr and figure p's'q'r are shown in the coordinate grid below
which statement describes how figure pqsr was transformed to form the image p'q'r's?
A. a translation across the x-axis
B.a reflection across the x-axis
C.a translation across the y-axis
D. a reflection across the y -axis
Answer:
D
Step-by-step explanation:
A translation would be shifting the figure in any direction, but the figure would retain it's shape and pqrs would all be at their same corners. A reflection means the figure will essentially be "flipped" across an axis, and in this case it would be the y-axis as you can imagine "folding" over the y-axis and having the figures line up.
