Mathematics

Rus_ich [418]3 years ago
7 0

Answer:

slope = \frac{7}{3}

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 )

Rearrange 7x - 3y = 21 into this form

Subtract 7x from both sides

- 3y = - 7x + 21 ( divide all terms by - 3 )

y = \frac{7}{3} x - 7 ← in slope- intercept form

with slope m = \frac{7}{3}

First 4 terms for 5 - 2n
vlabodo [156]

Answer:

3 , 1 , -1 , -3

Step-by-step explanation:

5 - 2n

n = 1 ;  5 - 2n = 5 - 2*1 = 5 - 2 = 3

n = 2;  5 - 2n = 5 - 2*2 = 5 - 4 = 1

n = 3;  5 - 2n = 5 - 2*3 = 5 - 6 = -1

n = 4;  5 -2n = 5 - 2*4 = 5 - 8 = -3

First 4 terms are :  3 , 1 , -1 , -3

Which scatterplot shows a linear association?
olasank [31]

Answer:

B

Step-by-step explanation:

A linear association means the function is a relation that can be shown with a line.

The first scatterplot is in the form of a parabola, and parabolas are the quadratic function form, meaning it cannot be linear.

Next, the second scatterplot goes diagonally, in a straight line. If we were to connect the dots using a line, then it would be a linear association, meaning that B is the correct answer.
