the point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = (x – 12). What is the standard form of the equation for this line?

Answers

Answer 1

Answer: y - 1 = 0.25(x - 12)
y - 1 = 0.25(x) - 0.25(12)
y - 1 = 0.25x - 3
+ 1   + 1
  y = 0.25x - 2
  -0.25x + y = 0.25x - 0.25x + 2
-0.25x + y = 2
  -1(-0.25x + y) = -1(2)
-1(-0.25x) - 1(y) = -2
0.25x - y = -2

Does a polygon have more sides or angles?

Answers

I think you're asking: "Which does a polygon have more of ... sides or angles ?"

This is a perfect example of where you spent more time and effort
posting your question on the internet than what it would take you
to answer it for yourself.

Can you draw a picture of a triangle ?
You'll see it has 3 sides and 3 angles.

Can you draw a picture of a square ?
You'll see it has 4 sides and 4 angles.

Can you draw a picture of a shape with 5 sides ?
You'll see that it has 5 angles.

Can you draw a shape with 6 sides (like s STOP sign) ?
You'll see that it has 6 angles.

By now, you would be getting the crazy hunch that maybe the
sides and angles of a polygon always happen in the same number.
THEN you would get on Brainly and ask: "I have been working
with some polygons, and I noticed that every polygon I tried had
the same number of angles as it had sides. Is this always true
for any polygon ?"

If I saw that question, I would jump on it with joy, because it feels
so good to help someone who doesn't mind putting some of his
own time and effort into a question.

I would answer "YES !", and then find 15 other characters to fill the minimum.

quadrilateral, triangle, hexagon, pentagon, etc are polygons
it depends on what kind of shapes like how many sides
but ex : rectangle has more sides than triangles so some of them yes, and some of them, no

To determine the appropriate landing speed of an airplane, the formula D = .1x 2 − 3x + 22 is used, where x is the initial landing speed in feet per second and D is the distance needed in feet. If the landing speed is too fast, the pilot may run out of runway; if the speed is too slow, the plane may stall. What is the appropriate landing speed if the runway is 800 feet long?

Fatima has saved $15,000 toward a down payment on a house. She makes $5,375 a month. What is the maximum loan she can take on a house?Don't you take the $5,375 a month, multiply it by 12, then multiply that answer by 2?
$5,375 x 12 = $64,500 x 2 = $129,000

Answers

Answer:

just use this formula and plug in your numbers from the question.

Maximum Loan for a house= $129,000

monthly pay * 12. So $5,375*12=$64,000.

$64,000*2=$129,000.

Maximum spent on a House=$144,000

$129,000+ $15,000= $144,000

Step-by-step explanation:

Rule from the lesson:

Maximum loan for a House = 2(Annual Gross pay) , that is 2*your annual gross pay.

Maximum spent on a House= Maximum Loan + Down Payment

If you want to find the loan for 2 years then you are right.Moreover in most of the cases you need t pay the interest too.But in this cases interest rate is not mentioned.

What is 0.063 in scientific notation?

Answers

Remember that you must change this number so that it is between 1 and 10, and then multiply it by a power of 10.

So first, you have to move the decimal point over 2 places to the right.

Since you are moving to the right, the exponent on ten will be negative; since you moved 2 decimal places, you know the exponent will be -2.

The answer is 6.3 x 10^-2.

Hope this helps!

To put a number into scientific notation, we multiply or divide the number by 10 over and over until we have a number between 1 and 10. But we can't just change a number so we have to account for what we did by describing how many times we multiplied or divided with exponents.

Each time we multiply by 10 the decimal moves 1 place to the right. Each time we divide by 10 the decimal moves 1 place to the left. The exponent we use will describe the number of times we moved the decimal to the right or left. The exponent will be positive or negative to describe the direction we need to move the decimal to represent our original number.

I know... that sounds confusing, but it's really easy! Let's do yours...

0.063

Now we need to move the decimal to get a number between 1 and 10. So we move the decimal 2 places to the right to get 6.3

Now we have to describe how to get to the original number with the exponents. We moved the decimal 2 places right so to get our number back we would have to move it back 2 places to the left so negative exponent 2... Here's how we represent it..

6.3 x 10^-2

So what that says is if we take 6.3 and divide it by 10 twice we will get our original number.

Let's do another...

0.000000000623

We move the decimal 10 places to the right so our scientific notation is

6.23 x 10^-10

What about very large numbers...

650,000,000,000 = 6.5 x 10^11

(In that one the exponent is positive because we have to multiply to get back to the original number)
