What is an equation of the line that passes through the points (-6,5) and (6,7)

Answers

Answer:

y = 1/6 x + 6

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

m = (7-5)/(6-(-6))

m = 2/12 = 1/6

Substitute x and y values with a pair of coordinates,

y = mx+c

7 = 1/6(6) + c

7 = 1 + c

c = 6

Thus, the equation is y = 1/6 x +6

Eduardo drew a scale drawing of the school cafeteria. He used a scale of 1 inch: 6 feet. In the drawing, the width of the cafeteria is 9 inches long. What is the actual width of the cafeteria?

Answers

Answer:

54 feet

Step-by-step explanation:

the answer is 54 feet because the ratio of 1:6 is equal to 9:54.

Multiply both sides of your original ratio (1:6) by nine. 1x9=9 and 6x9=54.

Determine if this series converges or diverges. Find the sum if possible. 250, 50, 10...

Answers

Answer:

Step-by-step explanation:

Answer:

312.5

Step-by-step explanation:

We have the series: 250, 50, 10...

As we can see, each subsequent term gets smaller and smaller. Eventually, it will be infinitesimally small. So, our series converges.

We can also see this from our common ratio. Each term is 1/5 of the previous term. Since our r 1/5 is less than 1, our series will converge.

Since it converges, we can indeed find our sum. First, we can write our series using summation. This will be:

[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }[/tex]

We can use the following infinite geometric series formula:

[tex]\displaystyle{\sum_{n=0}^{\infty} ar^n=\frac{a}{1-r}[/tex]

So, let's substitute 250 for a and 1/5 for r. This yields:

[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{1-\frac{1}{5}}[/tex]

Subtract:

[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{\frac{4}{5}}[/tex]

Divide. So, our series converges to:

[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=312.5[/tex]

And we're done!

Answers

Answer:

78.03

Step-by-step explanation:

14.50 + 10 + 48 = cost

cost = 72.25

What is the midpoint between the ordered pairs (10,-4) and (-9, 11)?
0 (0.5,3.5)
O (10.5,3.5)
O (-0.5, -0.5)
O (-10.5, -0.5)

Answers

Answer:

The answer would be (-0.5, -0.5)

Step-by-step explanation:

This is because when you solve for a mid-point you it's like solving for an average. You would take x1 and x2 and you would find the difference between them. Which would be -0.5. You do the same with y1 and y2. Which would be 3.5.

Write a quadratic function in standard form with zeros -4 and -3

Answers

Answer:

y = x² + 7x + 12

Step-by-step explanation:

Given the zeros x = - 4 and x = - 3, then the corresponding factors are

(x - (- 4) ) and (x - (- 3) ), that is

(x + 4) and (x + 3)

The function is then the product of its factors

y = (x + 4)(x + 3) ← expand using FOIL

= x² + 7x + 12

What is the point slope form

Answers

Answer:

Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).

Step-by-step explanation:

Answer: y - 2 = -6/5(x - 0)

You use the equation (y - y1) = m(x - x1)

Where y1 and x1 are coordinates of a point on the equation.

If the y intercept is 2, then the point (0, 2) is on the equation.

what is the slope for a line that is parallel to the line y=2/5x-4

Answer:

2/5

Step-by-step explanation:

The slope of the line

y=2/5x-4

is 2/5 since it is in the form y = mx+b where m is the slope

Parallel lines have the same slope so a line that is parallel to y=2/5x-4 has a slope of 2/5

How do you solve a simple equation?

Answers

Answer:

Solving Simple Equations

When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.

Solving an equation is the process of getting what you're looking for, or solving for, on one side of the equals sign and everything else on the other side. You're really sorting information. If you're solving for x, you must getx on one side by itself.

Step-by-step explanation:

Addition and subtraction equations

Some equations involve only addition and/or subtraction.

Example 1

Solve for x.

x + 8 = 12

To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides equation

X+8=12

- 8 - 8

_____ _____

X = 4

To check your answer, simply plug your answer into the equation:

X+8=12

(4)+8=12

12=12

There are 100 bolts in 5 bookcases. What is the unit rate in bolts per bookcase?

Answers

Answer:

20/1

Step-by-step explanation:

The unit rate in bolts per bookcase is 20bolts per bookcase

What is unit rate?

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We are Given that 100 bolts in 5 bookcase

We need to find the unit rate in bolts per bookcase

Number of bolts in 5 bookcases= 100

Number of bolts in 1 bookcases= 100/5

= 20

[2] Essay Bread by Margaret Atwood 1 Imagine a piece of bread. You don't have to imagine it, it's right here in the kitchen, on the breadboard, in its plastic bag, lying beside the bread knife. The bread knife is an old one you picked up at an auction; it has the word BREAD carved into the wooden handle. You open the bag, pull back the wrapper, cut yourself a slice. You put butter on it, then peanut butter, then honey, and you fold it over. Some of the honey runs out onto your fingers and you lick it off. It takes you about a minute to eat the bread. This bread happens to be brown, but there is also white bread, in the refrigerator, and a heel of rye you got last week, round as a full stomach then, now going moldy. Occasionally you make bread. You think of it as something relaxing to do with your hands. 2 Imagine a famine. Now imagine a piece of bread. Both of these things are real but you happen to be in the same room with only one of them. Put yourself into a different room, that's what the mind is for. You are now lying on a thin mattress in a hot room. The walls are made of dried earth, and your sister, who is younger than you, is in the room with you. She is starving, her belly is bloated, flies land on her eyes; you brush them off with your hand. You have a cloth too, filthy but damp, and you press it to her lips and forehead. The piece of bread is the bread you've been saving, for days it seems. You are as hungry as she is, but not yet as weak. How long does this take? When will someone come with more bread? You think of going out to see if you might find something that could be eaten, but outside the streets are infested with scavengers and the stink of corpses is everywhere. Should you share the bread or give the whole piece to your sister? Should you eat the piece of bread yourself? After all, you have a better chance of living, you're stronger. How long does it take to decide? Identify the type of paragraph listed below.Yesterday evening I got home from school around 4 o'clock.
