Identify the function shown in this graph

Answer:

C. y = 2x - 3

Step-by-step explanation:

Let's go through process of elimination!

First, we can see that the line intersects the y-axis at (0,-3), making the y-intercept -3. In the equation y = mx + b, b is the y-intercept. Therefore, we can easily take out A and D as the wrong answers because their b isn't -3.

Next, we should know that a line with a positive slope is going up, and this line, indeed, is going up. B can't be right because the slope is negative, meaning the line would go down. That leaves us with answer C as the correct choice.

On an application form, Mary needs to put her daughter's age in months. If her daughter is 4 2/3 old, what number should Mary put on the form?​

Answers

Answer:

56 months

Step-by-step explanation:

1 year= 12 months

4 years=12x4= 48 months

2/3 years=8 months

number she should put=48+8=56 months

Answer:

56 months

Step-by-step explanation:

4 2/3 years

= 4 years and 2/3 of a year

remember, 12 months = 1year

so, 2/3 of 1 year = 2/3 of 12 months

= 2/3 × 12

= 8 months.

For 4 years to months,

4 × 12 months = 48 months

so, 4 2/3 years = 48 + 8

Bedroom 1: 22 feet by 15 feet
Bedroom 2: 15 feet by 12 feet
Bedroom 3: 13 feet by 12 feet
A big home improvement store advertises the price of two types of flooring, shown below.

$7.25 per square foot
$6.75 per square foot plus a $100 fixed installation fee
Which of these two prices would be best for Darnell to estimate the total cost of new hardwood flooring in the three bedrooms?

Answers

Answer:

Look below for answer! Have a great day and please mark me brainliest!

Step-by-step explanation:

Bedroom 1: 22x15=330

330x7.25=2392.5

Bedroom 2: 15x12=180

180x7.25=1305

Bedroom 3: 13x12=156

156x7.25=1131

2392.5+1305+1131= 4828.5

Bedroom 1:  22x15=330

330x6.75=2227.5

Bedroom 2: 15x12=180

180x6.75=1215

Bedroom 3: 13x12=156

156x6.75=1053

2227.5+1215+1053+100= 4595.5

Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.

Complete the table for the function y = 0.1^x

The first step: plug values from the left column into the ‘x’ spot in the formula y=0.1^x.

* 0.1^-2 : We can eliminate the negative exponent value by using the rule a^-1 = 1/a. Keep this rule in mind for future problems. (0.1^-2 = 1/0.1 * 0.1 = 100).

* 0.1^-1 = 1/0.1 = 10

* 0.1^0 = 1 : (Remember this rule: a^0 = 1)

* 0.1^1 = 0.1

Our list of values: 100, 10, 1, 0.1

Now, we can plug these values into your table:

Given

Jimmy is selling used books at a yard sale.

A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill.

To find

The equation.

How to find the equation?

A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill.

Let c be the profit.

Profit = Selling price - cost price

c = 20 - (0.75)9

On simplifying, we get

(0.75)9 + c = 20

So the equation is (0.75)9 + c = 20.

The zeros are −4 and 5, because g(x)=−(x+4)(x−5).

Zeros of quadratc equation

Given the function  g(x)=−x^2+x+20

Factorize the expression

g(x) = -x^2 +5x - 4x + 20

g(x) = -x(x-5)-4(x-5)

g(x) = (-x-4)(x-5)

Equating the result to zero

x - 5 = 0

x = 5

Similarly, -x-4 = 0

-x = 4

x = -4

Hence the zeros are −4 and 5, because g(x)=−(x+4)(x−5)

The following table shows the amount of jeans or rye that can be produced using 1 hour of labor.CountryJeansRye(Pairs per hour of labor)(Bushels per hour of labor)Felicidad832Arcadia1224Initially, suppose Arcadia uses 1 million hours of labor per month to produce jeans and 3 million hours per month to produce rye, while Felicidad uses 3 million hours of labor per month to produce jeans and 1 million hours per month to produce rye. Consequently, Felicidad produces 24 million pairs of jeans and 32 million bushels of rye, and Arcadia produces 12 million pairs of jeans and 72 million bushels of rye. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and rye it produces.Felicidad's opportunity cost of producing 1 pair of jeans is _____ of rye, and Arcadia's opportunity cost of producing 1 pair of jeans is _____ of rye. Therefore, _____ has a comparative advantage in the production of jeans, and ____ has a comparative advantage in the production of rye.Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will produce ______ millions pairs per month, and the country that produces rye will produce ______ millions bushels per month.In the following table, enter each country's production decision on the third row of the table (marked "Production").Suppose the country that produces jeans trades 26 million pairs of jeans to the other country in exchange for 78 million bushels of rye.In the following table, select the amount of each good that each country exports and imports in the boxes across the row marked "Trade Action," and enter each country's final consumption of each good on the line marked "Consumption."When the two countries did not specialize, the total production of jeans was 36 million pairs per month, and the total production of rye was 104 million bushels per month. Because of specialization, the total production of jeans has increased by ____ million pairs per month, and the total production of rye has increased by _____ million bushels per month.Because the two countries produce more jeans and more rye under specialization, each country is able to gain from trade.Calculate the gains from tradethat is, the amount by which each country has increased its consumption of each good relative to the first row of the table.
