Answer: $116.15

Step-by-step explanation:

We first would start with the last  thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

Answer:

20.) A

y = 10x + 15

21.) C

Php 75.00

22.) B

Php 195.00

Step-by-step explanation:

20.)

We see an increase of 10y per x, which is where we get "10x"

This means that at x = 1, y = 15, which is where we get "+ 15"

21.)

Plug in 6 for x

y = 10(6) + 15

y = 60 + 15

y = 75

Php 75.00

22.)

Plug in 18 for x

y = 10(18) + 15

y = 180 + 15

y = 195

Php 195

The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles

Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.

Since the angles are supplementary, hence the required expression will be:

m∠10 + m∠14 = 180

Given that m∠10 = 70 degrees

70 + m∠14 = 180

m∠14 = 180 - 70

m∠14 = 110 degrees

Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

Answer:

f(x)=5x+25-1

8(x)- -2x-3

=30-1

=8x+6x

=29+14x

43x

The point of intersection of the two functions is (3, 27).

The system of equations is:

f(x) = 5x + 25 - 1 = 5x + 24

g(x) = 2x - 3

To solve this system, we can use the elimination method. We can eliminate the x-term by adding the two equations together.

f(x) + g(x) = 5x + 24 + 2x - 3 = 7x + 21

Solving for x, we get:

x = 21/7 = 3

Now that we know the value of x, we can plug it back into either equation to find the value of y. Let's use the equation for f(x).

f(x) = 5x + 24

f(3) = 5(3) + 24 = 27

Therefore, the point of intersection of the two functions is (3, 27).

To the nearest tenth, the point of intersection is (3.0, 27.0).

The proportion of the recipe required to make the grocery list is obtained from the recipe for the beans soup.

The grocery list is therefore;

Reason:

Amounts of beans soup Sam wants to make = 4 gallons

The recipe for the beans soup is as follows as obtained from an online home work document are;

Vegetable Bean Soup that Serves 4 with volume of 0.[tex]\overline 3[/tex] gallons

1.25 cups of honey beans

0.75 cup carrots

16 oz. vegetable broth

0.875 cup turnips

0.5 teaspoon salt

[tex]0.\overline 6[/tex] cup potato onions

0.125 teaspoon thyme

The amount of each ingredient Sam needs is given by the ratio of amount of soup Sam wants to make and the given amount of soup made by the ingredients as follows;

[tex]Multiple \ of \ ingredient \ amount = \dfrac{4}{0. \overline 3} = \dfrac{4}{\dfrac{1}{3} } = 4 \times 3 = 12[/tex]

Therefore, Sam has to buy twelve times the amount of each ingredient as follows;

12 × 1.25 = 15 cups of honey beans

12 × 0.75 = 9 cups of carrots

A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.

average rate of change:

($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year

initial value:

$350

B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.

If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is

(450 - 350) / (1 - 0) = 100/1 = 100

which is the same as the average rate of change.

Using the point-slope formula for a line, the equation you want is then

y - 350 = 100 (x - 0)

y - 350 = 100x

y = 100x + 350

Answer:

Step-by-step explanation:

[tex] - 5( - 9p + 7) = 6 - 3 + 7p \\ 45p - 35 = 3 + 7p \\ 45p - 7p = 35 + 3 \\ 38p = 38 \\ p = \frac{38}{38} \\ p = 1 \\ [/tex]

The slope of the line y = 5x - 3 is 5

Answer:

y= mx + b

and to my knowledge 5 would be your slope since m=5
