Answer:
Shorter piece is 3 ft, longer piece is 8 ft
Step-by-step explanation:
Set up two equations...
Let x be the length of the shorter piece, and let y be the length of the longer piece.
The whole board is 11 feet long, so
x + y = 11
He wants the longer piece to be 4 feet less than 4 times the length of the shorter board, so
y = 4x - 4
Substitute the second equation into the first equation....
x + 4x - 4 = 11 (y becomes 4x - 4)
Now solve for x
5x = 15 (combine like terms, add 4 to both sides)
x = 3 (divide both sides by 5)
Now substitute 3 in for x in either equation and solve for y...
y = 4(3) - 4
y = 12 - 4
y = 8

Answer:
-3 - 1 = 4/9(-5 - 4)
Step-by-step Explanation:
Point-Slope form uses the formula y-y1=m(x-x1).
m is the slope, which they gave you, so you can substitute it into the formula:
y - y1 = 4/9(x - x1).
They also gave you a first point (-5, -3) So you can substitute the x and y of those into the formula as well.
-3 - y1 = 4/9(-5 - x1)
y1 and x1 are for another point. By drawing a graph and then using the rise and run of the slope (up 4 and over 9), you can get another point (as shown in the picture).
Substitute the x and y values of that point into the equation as well and you have your answer:
-3 - 1 = 4/9(-5 - 4)
I don't know the answer choices but the inverse is F(x)=-x-13.
