What is the equation of the line that goes through the points (1,1) and 3,-3)

Answers

Answer 1

Answer:

y = -2x + 3

Step-by-step explanation:

[]Let us write an equation in slope-intercept form.

-> See attached

-> Our equation will start out as y = x

[] The slope can be found by taking the change in y divided by the change in x

-> [tex]\frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2[/tex]

-> Now our equation is y = -2x

[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.

-> y = -2x + b

(1) = -2(1) + b

1 = -2 + b

3 = b

-> Now our equation is y = -2x + 3, which is our final answer.

What Is The Equation Of The Line That Goes Through The Points (1,1) And 3,-3)
Answer 2

Answer:

y = -2x +3

Step-by-step explanation:

coordinates given (1,1) and (3,-3)

How to find equation? first find slope.

slope formula:

(y2-y1)/(x2-x1)

using this formula:

(-3-1)/(3-1)

-4/2

-2 ........this is slope also refereed as (m) in short form.

Use the formula:

y - y1 = m( x - x1)

using the formula:

y - 1 = -2( x - 1)

y -1 = -2x + 2

y = -2x +3

Answer:

The ratio is 1/2 : 2.

The value of the ratio is 1/4.

The amount of salt in the recipe is 1/4 the amount of flour.

Step-by-step explanation:

The ratio of the salt to flour is the amount of salt and the amount of flour

1/2 cup salt and 2 cups flour would be 1/2 : 2 The value of a ratio is the ratio simplified (if we make the 1/2 a whole number we would multiply both sides of the ratio by 2 to get 1:4 or 1/4).

1/2 cup is a fourth of 2 cups

I'm not super familiar with ratio values but I'm pretty sure this is correct.

MF lent $5,000 to Amit on January 01, 2020. (For simplicity, we assume there is no interest.) At the time of loan issuance, MF estimated that $500 of loans receivable would probably be uncollectible, based on their knowledge of historical credit losses.

Answers

From the information given regarding the loan, the amount that will be expected is $4500.

What is an uncollectible loan?

It should be noted that an uncollectible loan or account uncollectible are the receivables or loans that have no chance of being paid.

From the question, the amount lent is $5000 and the uncollectible is $500. Therefore, the amount that will be expected to be collected will be:

= $5000 - $500.

= $4500

In conclusion, $4500 will be expected.

What is the amplitude of the function shown in the graph?

Enter your answer in the box.

Answers

Answer:

1.5

Step-by-step explanation:

Amplitude: the height from the center line to the maximum or minimum point.

We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.

From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5

Therefore, the distance between them = -0.5 - -3.5 = 3

Divide by 2 = 3/2 = 1.5

Therefore, the amplitude = 1.5

If 1 inch represents 10 miles on a map, then how many inches will represent
120 miles?

Answers

Answer:

12 inches

Step-by-step explanation:

120/10 * 1 = 12 inches

Answer:

12 inches

Step-by-step explanation:

This question is asking for us to find the amount of inches that is represented to the amount of miles given (120 miles). In order to do this, let's divide the amount of miles that we need to find out for inches, over what information we already have. By dividing 120 over 10, that will give us the amount of inches that 120 miles represents. So:

120 miles / 10 miles = 12 inches.

This is true, because fractions are basically like division. As our example shows, 120 ÷ 10 = 12, which is true.

Two kindergarteners participated in a fundraiser event "Walk
Backwards for Hunger" last weekend. John walked 2/3 of a mile and Mary
walked 3/4 of a mile. Together, they raised $93.50. How much money, each, did
John and Mary raise? Just so you know, the amount raised is proportional to
distance walked

Answers

Answer:

John = $44   Mary = $49.50

Step-by-step explanation:

2/3 + 3/4 = 17/12

17/12x = 93.5

17/12x x 12 = 93.5 x 12

17x = 1122

17x/17 = 1122/17

x = 66

2/3x = 66 x 2/3

2/3x = 44

3/4x = 66 x 3/4

3/4x = 49.5

44 + 49.5 = 93.5

John earned $44 while Mary earned $49.5.

There are 1213 registered voters in Paul's village. During the last election 887 people actually voted. Which of the following is approximately the ratio of the number of the people who voted to the total number of registered voters in the village?

Answers

Answer:

3 : 4

Step-by-step explanation:

Given:

1213 = total number of registered voters887 = people who voted

ratio of people who voted to total number of registered voters:

To find the approx ratio, round both numbers to the nearest hundred:

887 ≈ 9001213 ≈ 1200

Therefore, 887 : 1213 ≈ 900 : 1200

The greatest common factor of 900 and 1200 is 300,

so we can reduce the ratio further by dividing both sides by 300:

⇒ 900 : 1200 = 3 : 4

13% can be written as 13/100

Now we solve for x

multiply both sides by 100

divide both sides by 13

x=20000

So, the company's total budget is 20,000
