Answer:

-2 $\frac{1}{10}$

Step-by-step explanation:

So this is simple substitution, $\frac{1}{2}$ (- $\frac{1}{5}$ )- $\frac{2}{3}$ (3)=> - $\frac{1}{10}$ - $\frac{6}{3}$ => $-\frac{1}{10}$ - 2= $-2\frac{1}{10}$ .

Which expressions are equivalent to 2 ln a + 2 ln b - ln a?

ycow [4]

Answer:

Choices 2, 3, and 5 are correct.

Step-by-step explanation:

Complete question is:

Check all that apply.

1. ln ab² - ln a

2. ln a + 2 ln b

3. ln a² + ln b² - ln a

4. 2 ln ab

5. ln ab²

ANSWER:

The given expression is : 2 ln a + 2 ln b - ln a

It simplifies to: ln a + ln b² = ln ab²

Checking the given options.

1. ln ab² - ln a = ln (ab²)/a = ln b²

FALSE

2. ln a + 2 ln b = ln ab²

TRUE

3. ln a² + ln b² - ln a = ln (a²b²)/a = ln ab²

TRUE

4. 2 ln ab = ln a²b²

FALSE

5. ln ab²

TRUE

Choose the graph which represents -6x - 5y = -10

Anna007 [38]

Answer:

y = 2 + ((-)6/5)x

Step-by-step explanation:

-6x-5y=-10

add 6x to both sides.

-5y = -10 +6x

divide both sides by -5

y = 2 - (6/5)x

Plug in 0 for x to get the y intercept:

f(0) = 2 - (6/5) (0)

y = 2

(0, 2) is the y intercept.

Do the same for values such as -1, -2, 1, and 2, etc.

Then graph it.

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40 how much would it cost to provide coffee for the whole

N76 [4]

Answer:

It would cost 15600 to provide coffee for the whole year.

Step-by-step explanation:

Given:

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40

Now, to find the cost to provide coffee for the whole year if you're place is open 5 days a week.

So, we have the unit rate, and we have to find the cost of 1.5 cup by multiplying 0.40.

1.5 cup of coffee cost $1.5\times 0.40=0.60.$

Thus, 1.5 cup cost 0.60.

If, 100 people drink 1.5 cups.

Then, total cost of 100 people drinking 1.5 cups of coffee = $100\times 0.60=60$

As, place is open 5 days a week.

So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:

$5\times 60\\\\=300.$

Hence, the cost of coffee in a week is 300.

In 1 year there are 52 weeks.

Now, to get the cost for the whole year we multiply 52 by 300:

$52\times 300\\\\=15600.$

Therefore, it would cost 15600 to provide coffee for the whole year.
