Answer:
y = -2x+5
Step-by-step explanation:
The formula for slope is y=mx+b.
(m = slope and b = y-intercept)
Plug in the numbers and you get your equation.
Answer:
A) 1:4
Step-by-step explanation:
#We first calculate the campus' area:
![a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2](https://tex.z-dn.net/?f=a%3Dlw%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B4%7D%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%5C%5C%3D0.125%20%5C%20mi%5E2)
#We then calculate the campus' map area in square ft:
![A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2](https://tex.z-dn.net/?f=A%3Dlw%5C%5C%5C%5C%3D0.5%20%5Ctimes%201%5C%5C%5C%5C%3D0.5%20ft%5E2)
Ratio is a comparison between two dimensions:
![Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4](https://tex.z-dn.net/?f=Ratio%3D%5Cfrac%7B0.125%7D%7B0.5%7D%5C%5C%5C%5C%3D0.25%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B4%7D%5C%5C%5C%5C%3D1%3A4)
Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4
ΔJKL : ΔXYZ
for two similar triangles we have this property:
![\frac{JK}{XY} =\frac{KL}{YZ}](https://tex.z-dn.net/?f=%20%5Cfrac%7BJK%7D%7BXY%7D%20%3D%5Cfrac%7BKL%7D%7BYZ%7D%20%20)
plugging the given values to find x
![\frac{6}{9} =\frac{8}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B9%7D%20%3D%5Cfrac%7B8%7D%7Bx%7D%20%20)
cross multiplying ,
6*x=8*9
6x =72
x=12
Answer:
To be honest with u my mom says she has know idea and nitherr do i and were math people so sorry.
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Distribute the negative which would get your 3x + 6 -3x + 6. The 3x would cancel out and you would add 6+6 = 12
