The table shows a proportional relationship between the number of pounds of bananas purchased and the total cost of bananas.

Liula [17]

Answer:

Choice A, C and E

Step-by-step explanation:

<em>Your table is poorly presented</em>

Given

x y

$\begin{array}{cc} {3} & {1.47} \ \\ {5} & {2.45} \ \\ {9} & {4.41} \ \ \end{array}$

First, we calculate the constant of proportionality (k)

$k = \frac{y}{x}$

For (3,1.47)

$k = \frac{1.47}{3}$

$k = 0.49$

For (5,2.45)

$k = \frac{2.45}{5}$

$k = 0.49$

For (9,4.41)

$k = \frac{4.41}{9}$

$k = 0.49$

From the above calculations, the constant of proportionality is 0.49.

So, the usable rows must also have 0.49 as their constant of proportionality

<u>Choice A</u>

$(x,y) = (2,0.98)$

$k = \frac{0.98}{2}$

$k = 0.49$ --- <em>This is usable</em>

<em />

<u>Choice B</u>

$(x,y) = (7,4.45)$

$k = \frac{4.45}{7}$

$k = 0.64$ --- <em>This is not usable</em>

<em />

<u>Choice C</u>

$(x,y) = (6,2.94)$

$k = \frac{2.94}{6}$

$k = 0.49$ --- <em>This is usable</em>

<em />

<u>Choice D</u>

$(x,y) = (1,0.54)$

$k = \frac{0.54}{1}$

$k = 0.54$ ---- <em>This is not usable</em>

<em />

<u>Choice E</u>

$(x,y) = (8,3.92)$

$k = \frac{3.92}{8}$

$k = 0.49$ --- <em>This is usable</em>

Answer:

Don't worry! This is not that hard! You got this! You can use this for checking :)

Plus we have to use x-y and use the numbers given for each question

15. x-y if x=6 and x=-3

6-(-3) negative plus negative equals positive

6+3= 9

16. x= -7 x=1

-7-1= -8

17. x=-2 y=-6

-2-(-6) negative plus negative equals positive

-2+6= 4

18. x=9 y=11

9-11= -2

19. x=-1 y=-1

-1-(-1)

-1+2= 1

20. x=-5 y=5

-5-5= -10

21. The high temp. is 6 and the low temp. is -3 It sasking for the differnece between the two.

6-(-3)

6+3=9

The difference between the high temp. and low temp. is 9 degrees Fahrenheit

22. This question is a little tricky but don't worry!

From -7 to 7. To reach -7 to 0, that is 7 degrees. To reach 7 from 0, that is also 7 degrees. So you add 7 and 7!

7+7= 14

The temperature increased 14 degrees Fahrenheit.

Hope this helps! Good luck on your quiz and I hope you pass :)
