Answer:
21.758
Step-by-step explanation:
If you draw the triangle out, you find that cos 41 = x/28.83, when x is equal to the side opposite the 49 angle
Simplify this into 28.83 cos 41, and plug it into the calculator and you get
21.75827.
Answer: 
Step-by-step explanation:
Given
The rug is 4 feet longer than its width
Suppose the length of the width is x
Length is given by x+4
So, the product of length and width is equal to the area of the rug
![\Rightarrow x\left(x+4\right)=A\quad\quad [\text{A=Area of rug}]](https://tex.z-dn.net/?f=%5CRightarrow%20x%5Cleft%28x%2B4%5Cright%29%3DA%5Cquad%5Cquad%20%5B%5Ctext%7BA%3DArea%20of%20rug%7D%5D)
Answer:
y = -9x + 14
Step-by-step explanation:
y + 4 = -9 (x -2)
y + 4 = -9x +18
y = -9x + 14
Answers:
- slope = 1
- equation is y = x-4
============================================
Explanation:
Two points on this diagonal line are (0,-4) and (1,-3)
Let's apply the slope formula to get the following
m = (y2-y1)/(x2-x1)
m = (-3-(-4))/(1-0)
m = (-3+4)/(1-0)
m = 1/1
m = 1
The slope is 1. We can think of it as 1/1 to indicate "go up 1, and over to the right 1". In other words, slope = rise/run = 1/1.
----------
Note how the graph crosses the y axis at -4, so this is the y intercept.
Since the y intercept is -4, this means b = -4
So with m = 1 and b = -4, we go from y = mx+b to y = 1x+(-4) which simplifies to y = x-4
