Answer:
25 2/7
Step-by-step explanation:
88.50/3.50 divide 88.50 by 3:50
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
Answer:
option 3
Step-by-step explanation:
Answer:
k(x) - h(x) = (3x + 7)
Step-by-step explanation:
Given functions are,
h(x) = x - 5
k(x) = 4x + 2
We have to find k(x) - h(x).
Step I
k(x) - h(x) = (4x + 2) - (x - 5)
Step II
Combine like terms,
k(x) - h(x) = (4x - x) + (2 + 5)
Step III
k(x) - h(x) = 3x + 7
Hence, k(x) - h(x) = (3x + 7) is the answer.
Answer:
Each side of the square is 13 inches long. The area of the original square is 169 square inches. The area of one of the rectangles is 84.5 square inches.
Step-by-step explanation:
The shorter side of the rectangle is named as X and the longer side is 2X because the piece of paper is folded in half.
So the perimeter of one of the rectangles is given by the following equation:

So we can find X by solving this equation:
2X+4X=39 in
6X=39 in
X=39 in ÷ 6
X=6.5 in
The sides of the square are equal to 2X, so, each side of the square is 13 in.
The area of the square is given by:

The area of one of the rectangles is given by:
