SOMEONE HELP ME WITH THIS PLS

Answers

Answer:

D

Step-by-step explanation:

You add the "columns."  The equations are arranged so that like terms are stacked vertically.  3x and 7x are like terms; when you add them, you get 10x.

-y and y are like terms; when you add them, you get 0 (that doesn't appear in the sum).

-5 and 15 are like terms; add them to get 10.

The sum of the two equations is the equation 10x = 10.

William sold half of his comic book collection then purchased 10 more. He now has 24 comic books . How many books did William begin with?

Answers

Answer:

28

Step-by-step explanation:

24-10=14

14x2=28

Answer:

willaim had 28 comic books to begin with

Step-by-step explanation:

So we can take 24-10=  to see how many comics he had before his total of 24  which :

24-10=14

Then we want to find how many he had in the beging so to reverse division we would use multiplication so we would do 14x2=  because a half x a half will equal a whole :

14x2=28

So therefor William started of with 28 comic books

Rate in Math - The speed of something happening in a certain amount of time, it is usually consistent.

Rate in Physics - Rate means rate of change. Basically, how much a certain quantity changes with respect to another quantity that is also changing. You may also sometimes hear the term gradient which describes the same thing.

To find how many miles she will run in 6 days we will multiply our [tex]Rate[/tex] by our Time, to find our distance, [tex](Miles, Physics)[/tex]

Our equation

is the function y = -7 a linear function?

Answers

Answer: Yes it is linear.

Explanation:

The given equation is the same as y = 0x - 7. It matches the form y = mx+b which is slope intercept form of a linear equation.

The slope m = 0 always applies to horizontal lines. All points on this line have a y coordinate of -7.

What is the slope of the line ?

Answers

The slope at the line would be the 360 point turn.

The slope of the line would be 2/3, I think… I can’t really tell because the image is bad quality.

If you can put up a better image or tell me two ordered pairs from the line, I can give you the slope. :)

60. Write the equation of a line through the point (-2,6) with a slope -5.

Answers

Answer:

y = - 5x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 5 , then

y = - 5x + c ← is the partial equation

To find c substitute (- 2, 6 ) into the partial equation

6 = 10 + c ⇒ c = 6 - 10 = - 4

y = - 5x - 4 ← equation of line

Answers

Answer:

f(-4) = -6

g(2) = -14

Step-by-step explanation:

To evaluate a function we must plug in the values of x. So for:

f(x) = 2x+2

we have:

f(-4) = 2(-4)+2

then we simplify:

f(-4) = -8+2

so f(-4) = -6

Now the same steps are taken for g(x) in which the answer would be -14.

Round 61.373737842 to the nearest ten-millionth ​

Answers

Answer:

61.3737378

Step-by-step explanation:

First find the ten millionth digit, and the digit after it.

The digit "8", the seventh digit to the right of the decimal point is the ten millionth digit.

As the digit after "8" is 4, which is less than 5, so simply round the digit "4" down.

Thus the answer is 61.3737378

Find the quotient. Answer

Answers

In order to divide by a fraction, keep the first fraction, and multiply it by the reciprocal of the next fraction. So 2/5 divided by 4/7 is actually just 2/5 x 7/4. This equals 14/20, which is 7/10. So the answer is B. Hope this helps you!

What number is 133% of 200

Answers

Rewrite 133% as a decimal by dividing by 100:

133% = 1.33

Now multiply:

200 x 1.33 = 266

Answer: 266

133% of 200 = 266

Explanation:

133 of 200 can be written as:

133/200

To find a percentage, we need to find an equivalent fraction with the denominator 100. Multiply both numerator & denominator by 100

Multiply both numerator & denominator by 100 Therefore, the answer is 66.5%If you are using a calculator, simply enter 133÷200×100 which will give you 66.5 as the answer and as we know 66.5 is also known as 226.
