Answer 2

Step-by-step explanation:

9+8-7=(9+8)-7=17-7=10

7-5+6=(7-5)+6=2+6=8

-6*4(-1)=-6*(-4)=24

8/4*2=2*2=4

3(6+7)=3*13=39

5(10-1)=5*9=45

72/9+7=8+7=15

48/(4+4)=48/8=6

Pls solve this question ASAP!!!

Answers

Step-by-step explanation:

[tex] \frac{1}{x} - \frac{1}{x - 2} = 3[/tex]

× All by x(x-2) both sides of equation

(x-2)-x = 3x(x-2)

x-2-x = 3x² - 6x

-2 = 3x² - 6x

0 = 3x² - 6x +2

3x² - 6x + 2 = 0

and use the formula

The length of XY is? I can’t figure this one out

Answers

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

Thank you

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)

Answers

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]
