Answer:
Step-by-step explanation:
Let the equation be of the form
be the equation, where k=-3 is the horizontal asymptote.
The equation now becomes:
The curve passes through (0,0)
a=3
This implies that:
We again substitute (1,3)
The required equation is
Answer:
71 1/2 square feet
Step-by-step explanation:
We want to find the area of the wall that will be painted.
We need to find the area of the two windows and subtract it from the area of the wall.
Each window is 3 1 /2 ft by 4 1/2 ft. The area of each window is therefore:
A = L * B
A = 7/2 * 9/2 = = 63/4 square feet = 15 3/4 square feet
The two windows therefore have an area of:
2 * 63/4 = 63/2 = 31 1/2 square feet.
The wall measures 12 7/8 ft by 8 ft. Therefore, the area of the wall is:
A = 103/8 * 8 = 103 square feet
The area of the wall that will be painted is therefore:
A = 103 - 31 1/2 = 71 1/2 square feet
Slope, m, is y2-y1 / x2-x1 or 7- -1 / 10-2, or 8/8, or 1
using the 1st point we get
y+1=x-2
using the second we get
y-7=x-10
both are correct
