Hi! I was wondering, how do you find the rise and the run of slopes? I am new to it.

Answer:

M = (Y2 - Y1) / (X2 - X1)

Step-by-step explanation:

First, look at a graph of a line and find two points, 1 and 2. You can use any two points on a line. The slope will be the same between any two points on a straight line.

Note the X and Y value for each of the points.

Now we'll designate the X and Y value for points 1 and 2. We'll use subscripts to identify them in the slope formula.

Hope this helps!

Answer:

3rd option

Step-by-step explanation:

( $\frac{f}{g}$ )(x)

= $\frac{f(x)}{g(x)}$

= $\frac{2x^2-5x-3}{2x^2+5x+2}$ ← factorise numerator and denominator

= $\frac{(x-3)(2x+1)}{(x+2)(2x+1)}$ ← cancel (2x + 1) on numerator/ denominator

= $\frac{x-3}{x+2}$

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is

CaHeK987 [17]

Answer:

The System of equation is $x+y=29, 5x + 2y = 100$ .

Step-by-step explanation:

Given:

Let 'x' be the number of questions worth 5 points.

Let 'y' be the number of questions worth 2 points

Total Number of Problems = 29

So the Total Number of Problems is equal to sum of the number of questions worth 5 points and the number of questions worth 2 points.

Framing in equation form we get;

$x+y=29$ .

Also Given:

Test is of Total Points = 100

Now Total points in test is equal to sum of the number of questions worth 5 points multiplied by and the number of questions worth 2 points multiplied by 2.

Framing in equation form we get;

$5x+2y=100$
