Answer:
Daniiel is 33 years old.
The son is 7 years old.
Step-by-step explanation:
x+26=3x
The x represents the son.
To solve for x:
-26=x-3x
-26=-2x
x=13
Since the father will be 3 times his son's age in six years we subtract 6.
x=7
This means the son is 7 years old as of right now. To find the father's age you do 7+26=33
28/4 = 7...and since the price fell, it would be -7 per day
Answer:
C. ![y = -x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-x%20%2B%202%20)
Step-by-step explanation:
First, find the slope, m, of the line that passes through the two given points.
Slope = ![\frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1](https://tex.z-dn.net/?f=%20%5Cfrac%7Brise%7D%7Brun%7D%20%3D%20%5Cfrac%7B-2%7D%7B2%7D%20%3D%20-%5Cfrac%7B1%7D%7B1%7D%20%3D%20-1%20)
Next, determine the y-intercept, b.
The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.
Now, to get an equation of the line, substitute m = -1, and b = 2 in
.
✅The equation would be:
![y = -1x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-1x%20%2B%202%20)
![y = -x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-x%20%2B%202%20)
Answer:
1
Step-by-step explanation:
(-6,4) and (2,12)
slope = m = (y2 - y1) / (x2 - x1)
= 12 - 4 / 2 - (-6)
= 8/8
= 1
