Answer:
She has 14 feet left
Step-by-step explanation:
1 yard = 3 feet of fabric
8 yards x 3 feet/yard = 24 feet
24 - 10 = 14 feet
Answer:
![C(x)=35x+50](https://tex.z-dn.net/?f=C%28x%29%3D35x%2B50)
Electrician's fee: $50.
Charges per hour: $35
Step-by-step explanation:
Let x represent number of hours and y represent amount charged.
We have been given that an electrician charges $120 after 2 hours of work and $190 after 4 hours of work.
We can represent this information with two points as (2,120) and (4,190).
First of all, we will find slope using these points.
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Now, we will slope-intercept form of equation
to get our required equation as:
![y=35x+b](https://tex.z-dn.net/?f=y%3D35x%2Bb)
Substitute coordinates of point (2,120) to find the y-intercept.
![120=35(2)+b](https://tex.z-dn.net/?f=120%3D35%282%29%2Bb)
![120=70+b](https://tex.z-dn.net/?f=120%3D70%2Bb)
![120-70=70-70+b](https://tex.z-dn.net/?f=120-70%3D70-70%2Bb)
![50=b](https://tex.z-dn.net/?f=50%3Db)
Therefore, our required function would be
.
The electrician's fee would be $50 as it the initial amount or y-intercept.
The electrician charges $35 per hour as the slope of the line is 35.
Answer:
27 more
Step-by-step explanation:
7/11 x 99 = 63
4/11 x 99 = 36
63-36 = 27
Answer:
1 week 8 days
that's the pattern
subtract 2 weeks add 2 days
brainliest would be nice
have a nice day
