Answer 1

Answer:

Answer:

Step-by-step explanation:

x=intercept is when the line intersect with the x axis when y=0

6: x intercept (1,0)

y intercept is when the line intersect with y axis at certain point or when x=0

y intercept (0.-24)

5: (0,-4) the y intercept

( 25,0) is the x intercept

21: (0,20) y intercept

(6,0) x intercept

22: (8,0) x intercept

(0 , 4) the y-intercept

Answer:

a. the line that passes through the most data points.

Step-by-step explanation:

Regression analysis, is used to draw the line of‘ best ﬁt’ through co-ordinates on a graph. The techniques used enable a mathematical equation of the straight line form y=mx+c to be deduced for a given set of co-ordinate values, the line being such that the sum of the deviations of the co-ordinate values from the line is a minimum, i.e.

A line drawn from one corner of a rectangle to the opposite corner is called

Answers

The corner of a rectangle is called the vertex of the rectangle.

Joining any two adjacent vertices is the side of the rectangle.

Joining any two vertices which are opposite to each other is called a diagonal of the rectangle.

The length of both the diagonals of a rectangle is always equal.

Final answer:

A line drawn from one corner of a rectangle to the opposite corner is called a diagonal in mathematics. It's a vector contains two components: the x-component and the y-component that are parallel to the x-axis and y-axis, respectively.

Explanation:

In the field of mathematics, a line drawn from one corner of a rectangle to the opposite corner is referred to as a diagonal. This line is equivalent to a vector that encompasses two components. The x-component Ax is the side of the rectangle that is parallel to the x-axis and the y-component Ay is the side parallel to the y-axis. To visualize it, consider a rectangle with corners A, B, C, and D. Draw a line from corner A to corner C. This line is the diagonal of the rectangle.

#SPJ3

the perimeter of a triangle is 8x+3y. The length of two sides of the triangle are 4x+y and 2x-3y. Find the measure of the third side of the triangle.

Answers

Perimeter = Sum of three sides.

Let the third side be = t

Perimeter = 8x + 3y

8x + 3y = (4x + y) + (2x - 3y) + t

8x + 3y = 4x + y + 2x - 3y + t

8x + 3y = 4x +2x + y - 3y + t

8x + 3y = 6x - 2y + t

8x - 6x + 3y + 2y = t

2x + 5y = t.

Therefore third side = 2x + 5y

Bob and James are finishing the roof of a house =. Working alone, Bob can shingle the roof in 10 hours. James can shingle the roof in 16 hours. How long will it take them working together to shingle the roof? Round your answer to the nearest hundredth if necessary.A) 13 hours
B) 26.67 hours
C) 6.15 hours
D) 0.04 hours

Answers

Bob can do a tenth of the roof in an hour
James can do a sixteenth in an hour

Bob can do 16/160 of the roof in an hour
James can do 10/160 of the roof in an hour

Together they do 26/160 of the roof in an hour
160/26 = 6.15 (to 2 d.p.)
