Answer:
15mi
Step-by-step explanation:
We can use the pythagorean therom to get 12^2+9^2=c^2. 144+81=c^2
c^2=225. c=15. 15mi
Answer:
y=4/5x-8
Step-by-step explanation:
The slope intercept form, or y=mx+b, has m to represent the slope and b to represent the y intercept, or the point where the function crosses the y-axis. Therefore, the equation you should use is y=4/5x-8. From here, if you plug in either a known x value or a known y value, you can find the other one. Hope this helps!
The answer is 10 x 62. He has 62 across, and 10 vertically. To find how many total he needs, you have to multiply both together. I hope this helps!
The equation of the line that fit the data is 2 x + 3 y = 398
Step-by-step explanation:
To find the equation of a line from two points on the line use this form
, where
and
are two points on the line- (x , y) are the coordinates of any general point on the line
∵ A line passes through points (64 , 90) and (97 , 68)
∴
= 64 and
= 90
∴
= 97 and
= 68
- Substitute these values in the rule above
∴ ![\frac{y-90}{x-64}=\frac{68-90}{97-64}](https://tex.z-dn.net/?f=%5Cfrac%7By-90%7D%7Bx-64%7D%3D%5Cfrac%7B68-90%7D%7B97-64%7D)
∴ ![\frac{y-90}{x-64}=\frac{-22}{33}](https://tex.z-dn.net/?f=%5Cfrac%7By-90%7D%7Bx-64%7D%3D%5Cfrac%7B-22%7D%7B33%7D)
∴ ![\frac{y-90}{x-64}=\frac{-2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7By-90%7D%7Bx-64%7D%3D%5Cfrac%7B-2%7D%7B3%7D)
- By using cross multiplication
∴ 3(y - 90) = -2(x - 64)
- Simplify
∵ 3(y) - 3(90) = (-2)(x) - (-2)(64)
∴ 3 y - 270 = -2 x + 128
- Add 2 x for both sides
∴ 2 x + 3 y - 270 = 128
- Add 270 to both sides
∴ 2 x + 3 y = 398
The equation of the line that fit the data is 2 x + 3 y = 398
