John drew the line of best fit on the scatter plot shown. A graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 15 at increments of 1 and scale along y axis from 0 to 15 at increments of 1. The ordered pairs 0, 3 and 1, 2 and 2, 4 and 3, 6 and 4, 6 and 5, 8 and 6, 10 and 7, 11 and 8, 12 and 9, 12 and 10, 14 are shown on the graph. A straight line joins the ordered pairs 0, 2 and 10, 14. What is the equation of this line of best fit in slope-intercept form? y = 2x + 6 over 5 y = 5 over 6x + 2 y = 2x + 5 over 6 y = 6 over 5x + 2

Answers

Answer 1

Answer: Equatin of a line in slope intercept form is y = mx + c; where m = (y2 - y1)/(x2 - x1) = (14 - 2)/(10 - 0) = 12/10 = 6/5

Equation of a line is obtained by (y - y1) = m(x - x1)
(y - 2) = 6/5(x - 0)
y - 2 = 6/5x
y = 6/5x + 2

Answer 2

Answer:

Answer:

y = 6/5x + 2

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 12 feet more than the length of the shortest side.Find the dimensions if the perimeter is 136 feet

Answers

x - the shortest side

x + 28

The sum of these must be equal to the perimeter of the flower bed, so

x + 2x + x + 28 = 184

4 x + 28 = 184 Combined like terms

4x = 156 Subtracted 28 from both sides

x = 39 Divided both sides by 4.

So the dimensions are 39 feet, 78 feet, and 67 feet

How many integers between 160 and 279 inclusive, are divisible by 7?

Answers

Answer:

Step-by-step explanation:

We can put this as an AP (arithmetic progression).

The first number, after 160, that is divisible by 7 is:

161

The last number before 279 that is divisible by 7 is:

273

We can use the formula:

$t_n=a+(n-1)d$

Where

tn is the nth term [here we take the last one, 273

a is the first term [161]

d is the common difference [7]

and n is the number of terms, we are trying to find this.

Substituting we get:

$t_n=a+(n-1)d\n273=161+(n-1)(7)\n273=161+7n-7\n273=154+7n\n7n=119\nn=17$

Hence, there are 17 integers
