Which statement about the ordered pairs (3, −8)(3, −8) and (4, 4)(4, 4) is true for the equation 3x−y4=11

2 answers:

6 0

The answer is D.) Neither ordered pair is a solution.

The reason being:

If we look at the ordered pair (3,-8) and plug it into the equation like so:

3(3)-(-8)4=11
9-32=11
-23=11
FALSE

Now let's look at the ordered pair (4,4):

3(4)-4(4)=11
12-16=11
-4=11
FALSE

We see that neither ordered pair works, so the answer is D.) neither is a solution.

Hope this helped :)

store announced that their $500 appliances were on sale for $475 what is the percent discount on the appliances

Aleks04 [339]

Answer:

We are given that a store announced that their $500 appliances were on sale.

The price of the appliances after discount is $475.

We are required to find the percent discount on the appliances.

To find the percent discount, we have to use the below formula:

$\frac{(Actual-discounted)}{Actual} \times 100\%$

$\frac{500-475}{500}\times 100\%$

$\frac{25}{500} \times 100\%$

$0.05 \times 100\%$

$5\%$

Therefore, the percent discount on the appliances is 5%

Lapatulllka [165]

The real distance fro the shop to the store is 24 km

<em><u>Solution:</u></em>

Given that, Jakes map shows the distance from the bake stars cafe to the restaurant supply store as 3 centimeter

Scale of the map is 1 centimeter to 8 kilometers

Therefore, scale is:

$1\ centimeter : 8\ kilometer$

Let "x" be the real distance from the shop to the store

Then by proportion, we get,

$\frac{1\ centimeter}{8\ kilometer} = \frac{3\ centimeter}{x\ kilometer}\\\\\frac{1}{8} = \frac{3}{x}\\\\x = 3 \times 8\\\\x = 24$

Thus real distance fro the shop to the store is 24 km

<h3><u>Question:</u></h3>

Jody is buying a scrap book and designed paper she has 40 dollars and needs at least 18.25 to buy a scrap book each seet of paper cost 0.34 how may sheets of paper can she buy

<h3><u>Answer:</u></h3>

Jody can buy 63 sheets of paper

<h3><u>Solution:</u></h3>

Jody has 40 dollars

Thus, she can spend less than or equal to 40 dollars

She needs at least 18.25 to buy a scrap book

Each seet of paper cost 0.34

Let "s" be the number of sheets of paper

Then,

$18.25+0.34s\leq 40\\\\Subtract\ 18.25\ from\ both\ sides\\\\0.34s \leq 40-18.25\\\\0.34s\leq 21.75\\\\Divide\ both\ sides\ by\ 0.34\\\\s\leq 63.9$

Thus Jody can buy 63 sheets of paper
