Answer:

Table A represents a function, but Table B does not represent a function.

Step-by-step explanation:

We have to select the correct option among the given 4 options after judging the given two tables attached to this question.

The first table shows that for each x values there is only one y value. Therefore, this is a function.

But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.

Hence, table B is not a function. it is just a relation. (Answer)

Answer:

(-5, 3)

Step-by-step explanation:

The coordinates of the midpoint are the averages of the endpoints.

-1.5 = (x + 2) / 2

-3 = x + 2

x = -5

6 = (y + 9) / 2

12 = y + 9

y = 3

Bridget purchased 3 pairs of shoes online. The total bill of $126.81 included a $7.50 shipping charge and 6% tax on the total pu

Alika [10]

Answer:

$37.

Step-by-step explanation:

Firstly, let's set the price of each pair of shoe to be x.

Since each pair of shoes costs the same, and there are three pairs, we can set the original price to be 3x.

Now, to apply the shipping charge, all we have to do is add 7.50 to 3x, getting 3x + 7.5.

Next, to apply a 6% tax, we can multiple the whole expression by (100% + 6%), getting (3x + 7.5) $\cdot$ 106%.

Since the whole bill foots to a total of $126.81, we can set the final equation to be:

$(3x + 7.5) \cdot 106\% = $126.81$

$(3x + 7.5) \cdot \frac{106}{100} = $126.81$

$3x + 7.5 = $126.81 \cdot \frac {50}{53}$

$3x = $119.6 - 7.5$

$3x = 112.1$

$x \approx \$37$

Hope this helped!

Alia has a AED 20 gift card for an online music store. All songs at the store have the same price. After Alia buys 3 songs, the

sladkih [1.3K]

Answer:

Remaining balance = AED 13.75

Step-by-step explanation:

Given that:

Amount of gift card = AED 20

Amount left after buying 3 songs = AED 16.25

Cost of 3 songs = 20 - 16.25 = AED 3.75

Cost per song = $\frac{3.75}{3}$

Cost per song = AED 1.25

Cost of 5 songs = 5(1.25) = AED 6.25

Remaining balance = 20 - 6.25 = AED 13.75

Hence,

Remaining balance = AED 13.75
