I'm guessing you mean what a linear function is, answer provided below...

What is a linear function?:

linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.

How to determine a linear function:

1. Identify the y-intercept from the graph.

2. Choose two points to determine the slope.

3. Substitute the y-intercept and slope into slope-intercept form of a line.

Here is a graph with a linear function:

Use the following formula to find the answer to this question: 

S * Q + M * Q = P 

Representations: 

S = The amount of points for short-answer questions. 

M = The a<span>mount of points for m</span>ultiple-choice questions. 

Q = Number of questions for each of the type of questions that add up to the total number of questions on the test (20 questions). 

P = Total points on the test. 

Since there is a total of 50 points on the 20 question test, you would need to divide up the amount of questions there are for each of the type there are on the test, short-answer, and multiple-choice. 

3 * Q + 1 * Q = P 

Now find how many of the type of questions there are out of 20 questions on the test that would add up to the total number of points on the test. 

3 * Q + 1 * Q = 50 

(15 + 5 = 20 questions on the test, 15 and 5 can be used for the number of questions for each type of question on the test). 

3 * 15 + 1 * 5 = 50 

45 + 5 = 50 

50 = 50 

So, your total number of multiple choice questions are: 5. 
And, your total number of short answer questions are: 15. 

I would go with D. for your answer. I may be wrong.

15 and 16 pls thank you ASAP ASAP
Delicious77 [7]
Number 16 is D & 15 is D because in number 16 8y can’t equal X but 8 can be in the X&Y’s place. As for number 15 the correct equation is 2y=0-4. Add to 2y and the equation is left with 2y=-4 divide that and you get a positive 2. Pls make my answer the Brainliest, I would rlly appreciate it...Please and Thank You!
