F(x)=y=2x+3
P (1,5)
Substitute x and y:
5=2*(1)+3
5=5 true
Point P (1,5) is on the graph of f.
Answer:
-4<x<2
Step-by-step explanation:

1. Take away the parentheses. x+2x+40+3x-50=15002
2. Add the X’s together.
x+2x+3x= 6x —> 6x+40-50=15002
3. Subtract 50 from 40.
40-50= -10 —> 6x-10=15002
4. Move -10 to the right hand side to make it positive.
6x=15002+10
5. Add 15002 and 10 together.
6x=15012
6. Divide 15012 by 6. Which makes the answer X=2502
The equation 3x+1/2=4
meaning x would equal 7/6
To find the area to be surrounded by a gravel path, we need to calculate two areas. First, the area of the whole space and, second, the area of the pond. We subtract these values to obtain the actual area for the gravel path.
A(whole space) = pi x (250)^2 = 62500π ft^2
A(pond) = pi x 200^2 = 40000π ft^2
Actual Area = 62500π ft^2 - 40000π ft^2 = 70686 ft^2 ----> OPTION A
