OleMash [197]

Answer:

y + 6.5 =-5 (x - 7.1)

Step-by-step explanation:

We can use the point slope equation of a line

y -y1 = m(x-x1)

We have a point and a slope

y - - 6.5 = -5 (x - 7.1)

y + 6.5 =-5 (x - 7.1)

ExtremeBDS [4]

Complete Question:

Here is the complete question:

<em>A lumber yard has five different lengths of 2 by 4 boards. Based on cost per linear foot, which is the best deal available on 2 by 4 boards at this lumber yard?</em>

<em>2 × 4 BOARD PRICES </em>

<em>8 foot board for $2.95 </em>

<em>10 foot board for $3.15 </em>

<em>12 foot board for $4.10 </em>

<em>16 foot board for $5.80 </em>

<em>20 foot board for $6.95</em>

Step-by-step explanation:

8 foot board for $2.95

$\frac{2.95}{8}= 0.36875$

10 foot board for $3.15

$\:\frac{3.15}{10}=0.315$

12 foot board for $4.10

$\frac{4.1}{12}=0.341$

16 foot board for $5.80

$\frac{5.8}{16}= 0.3625$

20 foot board for $6.95

$\frac{6.95}{20}= 0.3475$

Therefore, <em>10 foot board for $3.15</em><em> </em>is the best deal available on 2 by 4 boards at this lumber yard. It means you should be able to get 1 board for $0.315 when you buy 10 boards.

If my friend and i went to get ice cream, I have $30 and each ice cream is $5. What equation would help me solve this? I need an

Anna35 [415]

<h3>Hello there!</h3>

Your question asks to make an equation with the information that was given.

<h3>Answer: y = -5x + 30</h3>

In order to make an equation for your question. We would be making an equation with the formula: y = mx + b.

Formula: y = mx + b

m = change

x = amount of ice cream

b = starting value

We would need to gather the key information from the question.

Key information:

You have $30

Each ice cream cost $5

With the information above, we can make an equation for the question.

What we know is that you started with $30, so that means that 30 would be your b value (starting value).

Your equation should look like this:

y = mx + 30

Now, we know that each ice cream cost $5, but since we're paying for the ice cream, we would subtract that from our starting value. This means that our change would be -5, since we are taking away $5 each time we buy ice cream.

Your equation should look like this:

y = -5x + 30

The equation above would be the equation for your question.

We would do nothing to x but just leave it as is, since we don't know how many ice creams you're going to buy.

y = -5x + 30 should be your FINAL answer.

<h3>I hope this helps!</h3><h3>Best regards, MasterInvestor</h3>
