A) the rise in the roof is a reference to the change in the y axis in correspondence to the x axis, which is referred to as the horizontal change. to find the slope, put the rise 8 on the top and 24 on the bottom since the slope is the rise/run. The slope should be 1/3.
b) To find the slope for b), remember the formula y2-y1/x2-x1= slope. So minus y1(5) by y2(6) and divided by x2(2)-x1(3). The answer would be -1.
c) Rearrange the equation and you will find it's actually y=-9x+7, so the slope would be -9

•Slope is defined as "rise over run."
•Make sure that the line is straight. You can't find the slope of a line that isn't straight.
•Coordinates are the xand y points written as (x, y). It doesn't matter which points you pick, as long as they're different points on the same line.
•It doesn't matter which one you pick, as long as it stays the same throughout the calculation. The dominant coordinates will be x1 and y1. The other coordinates will be x2 and y2.
•Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
•Subtract the two y-coordinates from one another.
•Divide the y-coordinate's result with the x-coordinate's result. Reduce the number if at all possible.

The length of a rectangle is 3 centimeters less than four times its width. Its area is 10 square centimeters. Find the dimension
Kay [80]

Answer:

W = 2 cm

L = 5 cm

Step-by-step explanation:

A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. Its area, the amount of space inside it, can be found using the formula A = l*w. If the area is 10 cm² and the length is "3 cm less than 4 times the width" or 4w - 3, you can substitute and solve for w.

A = l*w

10 = (4w - 3)(w)

10 = 4w² - 3w

Subtract 10 from both sides to make the equation equal to 0. Then solve the quadratic by quadratic formula.

4w² - 3w - 10 = 0

Substitute a = 4, b = -3 and c = -10.

w = \frac{3 +/- \sqrt{(-3)^2 - 4(4)(-10)} }{2(4)} = \frac{3 +/- \sqrt{9 +160)} }{8} =  \frac{3 +/- \sqrt{169} }{8} = \frac{3+/-13}{8}

There are two possible solutions which can be found.

3 + 13 / 8 = 16/ 8 = 2

3 - 13 / 8 = -10/8 = -5/4

Since w is a side length or distance, it must be positive so w = 2 cm.

If the width is 2 cm then the length is 4(2) - 3 = 8 - 3 = 5 cm.

{4x+2y=10<br> y=2x-1<br><br>What is the value of x+y<br><br>A.3.125<br>B.2<br>C.4.5<br>D.3.5​
Evgen [1.6K]

Answer:

D.3.5

Step-by-step explanation:

4x+2y=10(given)

2x+y=5

y=5-2x-----(1)

y=2x-1------(2)(given)

Since the left side of the equations are the the same,

5-2x=2x-1

4x=6

x=1.5

Sub x=1.5 into eq(1),

y = 5-2(1.5) = 5-3 = 2

so, x+y = 1.5+2 = 3.5
