I'm assuming the function is f(x) = (2x+8)/(x^2+5x+6). If so, make sure to use parenthesis to indicate that you're dividing all of "2x+8" over all of "x^2+5x+6" as one big fraction. Otherwise, things are ambiguous and it leads to confusion.
Side Note: x^2 means "x squared"
Factor the numerator: 2x+8 = 2(x+4)
Factor the denominator: x^2+5x+6 = (x+2)(x+3)
There are no common factors between the numerator and denominator. So there is nothing to cancel out.
Recall that you cannot divide by zero. Something like 1/0 is undefined.
We need to find the x values that cause the denominator to be zero.
Set the denominator equal to zero and solve for x
x^2+5x+6 = 0
(x+2)(x+3) = 0
x+2 = 0 or x+3 = 0
x = -2 or x = -3
The x values x = -2 or x = -3 will lead to the denominator being zero. This means that the vertical asymptotes are x = -2 or x = -3 as shown by the blue dashed vertical lines in the attached image.
Answer:
1: 8 2/5
Step-by-step explanation:
4x5=20+3=23
3x5=15+4=19
23+19=42
42/5= 8 2/5
The answer is 9 since m and n are added together, you add the value of them together, which is 5 and 4, which makes 9
Answer:
Hello!
____________________
77 = 1 x 7 x 11
91 = 1 x 7 x 13
143 = 1 x 11 x 13
Step-by-step explanation: There are no HCF's except 1. So 1 is the highest common factor. HCF ( 77, 91 143 ) = 1
Hope this helped you!
15 even.
A good way to look at it is a clock. The 3 means 15 minutes and the 6 means 30 minutes.
6 divided by 3 = 2.
Hope this helps and makes sense!
