PLEASE ANSWER QUICKLY I WILL GIVE BRAINLIEST Mrs. Morales wrote a test with 18 questions covering spelling and vocabulary, Spelling questions W) are
worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible
on the test is 100
Part 1 out of 4
Write an equation in slope-intercept form to represent the number of questions on the test
The equation is y

Answers

Here's our data:

15 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:

x+y=15

5x + 10y= 100

So:

x+y=15

x= 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10

There are 10 spelling questions and 5 vocab questions

Please only respond if you know the answer I have this and more due at 12:59 (ignore the third tab lol)

Chris types at an average speed of 45 words per minute. He has already typed 1,500 words of his final paper. The paper has to be more than 3,750 words. Which of the following inequalities could be used to solve for x, the number of minutes it will take Chris to finish his paper? ANSWER CHOICES R IN COMMENTS

Answers

Answer:

C. 45x + 1,500 > 3,750

Step-by-step explanation:

You know he has already started on his paper with 1,500 words and he needs to have more words than 3,750 in his final paper which includes the 1,500. Thus, he would have 45x number of words remaining in his paper, according to his speed of 45 words per minute.

Remaining words + 1,500 words must be more than 3,750.

45x + 1,500 > 3,750

The > sign means that something on the left is more than something on the right.

Answer:

C. 45x + 1,500 > 3,750

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^

One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?

Good Luck!!

Answers

Answer:

17

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

Pretty sure that the answer is 17

Step-by-step explanation:

A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)

B is not a function because there isn't a constant for y.

C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.

D is also a function because of the equation on the right side.
