Answer: m = 3

Step-by-step explanation:

We can distribute both sides.

3*m + 3*7 = 6*m + 6*2

3m + 21 = 6m + 12

We can now combine like terms.

3m = 9

m = 3

Colleen is 15 years from retiring. She opens an account at the Savings Bank. She plans to deposit

Answer:

a) $169,234.59

b) $19,234.59

Step-by-step explanation:

The first question you must answer is whether Colleen will earn interest on her first deposit in the first year. That is, does she deposit the money at the first of the year or the end of the year?

The usual "annuity" formula assumes the deposit is at the end of the year, so no interest at all is earned on the last deposit made. If the deposit is at the first of the year, an "annuity due" formula is used, that multiplies the entire ending account value by the annual multiplier, 1.017 in this case.

a) Assuming an "annuity", the formula is ...

A = P((1 +r)^t -1)/r . . . . . for annual compounding at rate r for t years

A = $10,000(1.017^15 -1)/0.017 = $169,234.59 . . . . ending balance

b) Colleen has made 15 deposits of $10,000, for a total of $150,000, so the amount of interest earned is ...

$169,234.59 -150,000 = $19,234.59 . . . . interest earned

Meat costs $8.00 per pound at a store. What is the slope?

-BARSIC- [3]

Answer:

The slope is 8.

Step-by-step explanation:

If you were to graph the price of meat per pound, you would need to choose the x-axis and y-axis labels.

The x-axis is the independent variable, meat in pounds.

The y-axis is the dependent variable, price in dollars.

The price depends on the number of pounds you buy.

Slope is calculated using rise over run, or:

$m = \frac{rise}{run}$

"Rise" is the number of squares going up.

"Run" is the number of squares going to the right.

In the graph below, to go from one red dot to the next, you count 1 to the right and 8 going up.

$m = \frac{rise}{run}$

$m = \frac{8}{1}$

$m=8$

Therefore, the slope is 8.

Which of the following represents the set in words?

jekas [21]

Answer:

It's actually: None of these.

Think about it: In this case we have an inequality, of x ≤ 0.

This basically means, that x can be less than OR equal to 0.

But 0 is neither negative or positive, so we can eliminate the following answer choices:

- all positive integers

- all negative real numbers

- all positive real numbers

- all negative integers

And we are left with "None of these"
