Answer:
![8f + 8g - 9](https://tex.z-dn.net/?f=8f%20%2B%208g%20-%209)
Step-by-step explanation:
. (8f - 5 + 6g) - (-2g + 4)
![8f - 5 + 6g + 2g - 4 \\ 8f + 8g - 9](https://tex.z-dn.net/?f=8f%20%20%20-%205%20%2B%206g%20%2B%202g%20-%204%20%5C%5C%208f%20%2B%208g%20-%209)
Answer:
Number line C
Step-by-step explanation:
First, you isolate x. This gives you x>=3+4 or x>= 7. Next, you find a number line greater than or equal to which cancels out A and D. Now whichever line starts on 7, is the answer which is C
Answer:
B) The function shown is ![f(x)=\frac{(x-3)(x+1)}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B%28x-3%29%28x%2B1%29%7D%7Bx%7D)
Step-by-step explanation:
The given function is
![f(x)=\frac{x^2-2x-3}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%5E2-2x-3%7D%7Bx%7D)
This is an improper rational function because the degree of the numerator is greater than the degree of the denominator. This means the function has a slant asymptote and cannot have a horizontal asymptote.
The vetical asymptote is
.
We factor the numerator to get;
![f(x)=\frac{x^2-3x+x-3}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%5E2-3x%2Bx-3%7D%7Bx%7D)
![f(x)=\frac{x(x-3)+1(x-3)}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%28x-3%29%2B1%28x-3%29%7D%7Bx%7D)
The function shown is the same as ![f(x)=\frac{(x-3)(x+1)}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B%28x-3%29%28x%2B1%29%7D%7Bx%7D)
The zeros of this function are ![x=-1,x=3](https://tex.z-dn.net/?f=x%3D-1%2Cx%3D3)
The correct answer is B
Answer:$38.70
Step-by-step explanation:
20% = 5
48 / 5 = 9.6
20% = $9.60
48 - 9.6 = $38.7
The like terms are 4e and 7e
the coefficients are 4 and 7
the constant is 5
