Answer:
see the explanation
Step-by-step explanation:
we know that
The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function
I will analyze two cases
Part 1) we have
so
For x=0
substitute
therefore
The y-intercept is the point (0,0)
Part 2) we have
so
For x=0
substitute
therefore
The y-intercept is the point (0,-1)
Answer:
Length: 6 m
Width: 4 m
Step-by-step explanation:
Area: 24
Width: 2L - 8 m
Length: ?
Formula: A = W * L
Replace the variables:
24 = (2L - 8) * L
24 = 2 - 8L
0 = 2 - 8L - 24
or
2 - 8L - 24 = 0
Solve; if you don't know how to solve it using this method, let me know. It's the expression

5. (L-6) (2L+4)
6. L-6 = 0 AND 2L+4 = 0
L - 6 =0
L = 6
---------------------------------
2L = -4
L =
L = -2
Since the length cannot be negative, the only real value is 6.
Area: 24
Width: 2L - 8 m
Length: 6 m
Calculate width:
W = 2L - 8
W = 2(6) - 8
W = 12 - 8
W = 4 m
