If two numbers round to the same number it doesnt always mean they are equal, for example: 11 and 9 both round to ten but they are not the same number
Answer:
the fourth one
Step-by-step explanation:
every 2 hours will be a positive line segment relating to the 7 meters give you the point of 14 every 4 hours
(-1,1)(1,4)
slope = (4 - 1) / (1 - (-1) = 3/(1 + 1) = 3/2
y = mx + b
slope(m) = 3/2
use either of ur points....(1,4)...x = 1 and y = 4
now sub and find b, the y int
4 = 3/2(1) + b
4 = 3/2 + b
4 - 3/2 = b
8/2 - 3/2 = b
5/2 = b
equation is y = 3/2x + 5/2...but we need it in standard form
y = 3/2x + 5/2
-3/2x + y = 5/2.....multiply both sides by -2
3x - 2y = -5 <==== ur standard form equation
Answer:
multiplication property of equality
Step-by-step explanation:
Answer:
Slope = ![\frac{-4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-4%7D%7B3%7D)
4x + 3y = 23
Step-by-step explanation:
slope = ![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%3D%5Cfrac%7B-3-5%7D%7B8-2%7D%20%3D%5Cfrac%7B-8%7D%7B6%7D%20%3D%5Cfrac%7B-4%7D%7B3%7D)
The equation:
m is the slope
![y-y_{1}=m(x-x_{1} )](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%20%29)
y - 5 = -4/3 (x - 2) Multiply both sides by 3
3y -15 = -4 (x - 2)
3y - 15 = -4x + 8
3y + 4x = 8 + 15
3y + 4x = 23
4x + 3y = 23
