List your answer as an ordered pair ..please help<br>y= 4x - 3<br> y= -3x + 4

Kay [80]

To solve this, you know that both values listed (4x - 3 and -3x + 4) are equal to y, so you know that they also must be equal to each other! Therefore you can form the following equation:

4x - 3 = -3x + 4

Now you can add -3x to both sides to combine like terms:

7x - 3 = 4

Now add 3 to both sides:

7x = 7

Now if you divide everything by seven, you see that x = 1. Now that we have out x value, we can go ahead and plug it into one of the equations. This gives us:

y = 4(1) - 3

If we multiply out, we get:

y = 4 - 3
y = 1

So y also equals 1! Now that we have our answers, we can simply put them into an ordered pair which should be in the form of (x value, y value.)

Our final answer will be (1, 1).

Hope this helps!

Walter is helping to make cookies for a basketball tournament. He's made 15 cookies so far. His coach asked him to make at least

Hoochie [10]

Answer:

$5\leq x\leq 40$

Here, $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far

Step-by-step explanation:

Number of cookies made by Walter so far = 15

He is asked by his coach to make at least 20 cookies but no more than 55.

Let $x$ denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.

The inequality is $20\leq x+15\leq 55$

Now solve this inequality.

$20\leq x+15\leq 55\\20-15\leq x\leq 55-15\\5\leq x\leq 40$

You start your working career when you are 24 years old. Each month, you deposit $144 into a pension plan. You continue making d

Inga [223]

The balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.

<h3>What is future value?</h3>

The future value refers to the compounded future value of an asset, for example, a pension plan, based on a growth rate of interest for a future period.

The future value can be determined with the FV formula, table, or using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

N (# of periods) = 528 months (68 - 24 x 12 months)

I/Y (Interest per year) = 6%

PV (Present Value) = $0

PMT (Periodic Payment) = $144

<u>Results:</u>

FV = $372,134.19

Sum of all periodic payments = $76,032 ($144 x 528)

Total Interest = $296,102.19

Thus, the balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.
