Answer:
32.82
Step-by-step explanation:
You cross multiply so you get 15 x 2= 6 x c
this is 30= 6c. if you divide both sides by 6 you get c =5
Answer:
Option 3 is correct
Marty’s with a slope of 1/3
Step-by-step explanation:
Using slope intercept form:
The equation of line is:
....[1]
where,
m is the slope and b is the y-intercept.
Formula for Slope is given by:
....[2]
As per the statement:
Marty and Ethan both wrote a function, but in different ways.
Marty equation is:
![y+3 = \frac{1}{3}(x+9)](https://tex.z-dn.net/?f=y%2B3%20%3D%20%5Cfrac%7B1%7D%7B3%7D%28x%2B9%29)
using distributive property
we have;
![y+3 = \frac{1}{3}x+3](https://tex.z-dn.net/?f=y%2B3%20%3D%20%5Cfrac%7B1%7D%7B3%7Dx%2B3)
Subtract 3 from both sides we have;
![y= \frac{1}{3}x](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7B3%7Dx)
On comparing with [1] we have;
Slope of Marty = ![\frac{1}{3}=0.333..](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%3D0.333..)
Ethan wrote a function:
Consider any two values from the table we have;
(0, 10) and (2, 10.4)
Substitute these in [2] we have;
Slope of Ethan = 0.2
![\text{Slope of Ethan} < \text{Slope of Marty}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%20of%20Ethan%7D%20%3C%20%5Ctext%7BSlope%20of%20Marty%7D)
Therefore, . Marty’s with a slope of 1/3 function has the larger slope
X - y = 1....multiply by -5
5x - 4y = 0
---------------
-5x + 5y = -5 (result of multiplying by -5)
5x - 4y = 0
---------------add
y = -5
x - y = 1
x - (-5) = 1
x + 5 = 1
x = 1 - 5
x = -4
solution is (-4,-5)
