Basically, you just need to simplify it first, then combine like terms. 
(-4-x)-(3y-9x)
   = -4 - x - (3y - 9x)
   = -4 - x + -1(3y) + -1 (-9x)
   = -4 + -x + -1(3y) + -1(-9x)
   = -4 + -x + -3y + 9x
   = (-x + -9x) + (-3y) + (-4)
   = 8x + (-3y) + (-4)
   = 8x - 3y - 4

Do this by moving the decimal two places to the left.
0.25 is the decimal.
Now divide the whole number by the decimal.
60/0.25=240
60 is 25% of 240

Consider the function f(x)=3x-1 (over)x+4 (a) At which value of x will the function not have a solution? Explain your answer. (b
Irina18 [472]

Ans(a):

Given function is f(x)=\frac{3x-1}{x+4}

we know that any rational function is not defined when denominator is 0 so that means denominator x+4 can't be 0

so let's solve

x+4≠0 for x

x≠0-4

x≠-4

Hence at x=4, function can't have solution.


Ans(b):

We know that vertical shift occurs when we add something on the right side of function so vertical shift by 4 units means add 4 to f(x)

so we get:

g(x)=f(x)+4

g(x)=\frac{3x-1}{x+4}+4

We may simplify this equation but that is not compulsory.

Comparision:  

Graph of g(x) will be just 4 unit upward than graph of f(x).


Ans(e):

To find value of x when g(x)=8, just plug g(x)=8 in previous equation

8=\frac{3x-1}{x+4}+4


8-4=\frac{3x-1}{x+4}


4=\frac{3x-1}{x+4}


4(x+4)=(3x-1)


4x+16=3x-1


4x-3x=-1-16

x=-17

Hence final answer is x=-17
