Answer:

Step-by-step explanation:
Which function has zeros of -8, 1, and 3? A. y = (x − 3)(x + 8)(x − 1) B. y = (x + 1)(x − 8)(x + 3) C. y = x(x + 8)(x − 3) D. y = x(x + 3)(x − 8)
Answer:
A
Step-by-step explanation:
In each binomial, just flip the sign before the constant, and that number is a zero.
So for example if you have (x+1), a zero would be -1, if you have (x-8), a zero would be 8, etc.
The zeros of a function are the values of x, when the function equals 0.
The function that has zeros of -8, 1 and 3 is: (a) [tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex]
The zeros are given as:
[tex]\mathbf{Zeros = -8, 1, 3}[/tex]
Rewrite as:
[tex]\mathbf{x = -8, 1, 3}[/tex]
Equate to 0
[tex]\mathbf{x +8 = 0,\ x - 1 = 0,\ x - 3 = 0}[/tex]
Multiply the equations
[tex]\mathbf{(x +8) \times (x - 1) \times (x - 3) = 0\times 0 \times 0}[/tex]
[tex]\mathbf{(x +8) \times (x - 1) \times (x - 3) = 0}[/tex]
Express as a function
[tex]\mathbf{y = n(x +8) \times (x - 1) \times (x - 3) }[/tex]
Where:
[tex]\mathbf{n \ne 0}[/tex]
The above equation represents functions that have zeros of -8, 1, and 3
By comparing the options, we have:
[tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex] is [tex]\mathbf{y = n(x +8) \times (x - 1) \times (x - 3) }[/tex], where n = 1
Hence, the function that has zeros of -8, 1 and 3 is:
(a) [tex]\mathbf{ y = (x - 3)(x + 8)(x - 1)}[/tex]

The length of XY is? I can’t figure this one out
Answer:
[tex]32[/tex]
Step-by-step explanation:
Point M is the midpoint of XY since it is a bisector. Thus, XM = MY.
[tex]3x+1=8x-24[/tex]
Subtract 1 from both sides:
[tex]3x+1-1=8x-24-1[/tex]
[tex]3x=8x-25[/tex]
Subtract 8x from both sides:
[tex]3x-8x=8x-25-8x[/tex]
[tex]-5x=-25[/tex]
Divide both sides by -5:
[tex]\frac{-5x}{-5}=\frac{-25}{-5}[/tex]
[tex]x=5[/tex]
[tex]XM=3x+1=3(5)+1=15+1=16[/tex]
[tex]MY=8x-24=8(5)-24=40-24=16[/tex]
[tex]XY=16+16=32[/tex]
Your question has been heard loud and clear.
Length of XY is = 3x+1+8x-24 = 3x+8x + 1 -24 = 11x - 23
Length of XY = 11x-23
x= 5
Length of XY = 11(5)-23 = 32

× All by x(x-2) both sides of equation
(x-2)-x = 3x(x-2)
x-2-x = 3x² - 6x
