For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.
For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.
Answer:
Area of the whole rectangle = 11 x 12
= 132 cm^2
Area of the circle = πr^2
= 3.14 x 2 x 2
= 12.56 cm^2
Area of the shaded region = area of rectangle - area of circle
= 132 - 12.56
= 119.44 cm^2
Hope this helps!

Answer: There are 1436 bricks that he will need to make a brick wall.
Step-by-step explanation:
Since we have given that
Dimensions of a brick wall is given by
Length = 14.5 feet
Width = 0.5 feet
Height = 5.5 feet
Dimensions of a brick is given by
Length = 6 inch
Width = 4 inch
Height = 2 inch
We need to find the number of bricks :
So, Number of bricks is given by
![\text{ Number of bricks }=\frac{\text{ Volume of brick wall }}{\text{ Volume of brick}}\\\\=\frac{14.5\times 5.5\times 0.5\times 12\times 12\times 12}{6\times 4\times 2}\\\\=1435.5\\\\=1436](https://tex.z-dn.net/?f=%5Ctext%7B%20Number%20of%20bricks%20%7D%3D%5Cfrac%7B%5Ctext%7B%20Volume%20of%20brick%20wall%20%7D%7D%7B%5Ctext%7B%20Volume%20of%20brick%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B14.5%5Ctimes%205.5%5Ctimes%200.5%5Ctimes%2012%5Ctimes%2012%5Ctimes%2012%7D%7B6%5Ctimes%204%5Ctimes%202%7D%5C%5C%5C%5C%3D1435.5%5C%5C%5C%5C%3D1436)
Hence, there are 1436 bricks that he will need to make a brick wall.
Given :
Everyday Isabel swims 10-20 laps in a 50 meter pool.
The amount of time she spends swimming is represented by the function f(x) = 3x .
To Find :
The speed of Isabel.
Solution :
Distance travelled in x laps is, D = 50x .
It is given that time taken is, t = 3x .
So, speed of Isabel is given as :
![Speed=\dfrac{Distance}{Time}\\\\Speed = \dfrac{50x}{3x}\\\\Speed = \dfrac{50}{3}=16.67 \ m/s](https://tex.z-dn.net/?f=Speed%3D%5Cdfrac%7BDistance%7D%7BTime%7D%5C%5C%5C%5CSpeed%20%3D%20%5Cdfrac%7B50x%7D%7B3x%7D%5C%5C%5C%5CSpeed%20%3D%20%5Cdfrac%7B50%7D%7B3%7D%3D16.67%20%5C%20m%2Fs)
Hence, this is the required solution.
