Hope that helped I use this when I'm doing math. It's called cymath it explain how they got the answer.
You have f(x)=(<span>6x+9)/(x-5) and want to find the inverse function? Please note that the parentheses are obligatory here.
1. Replace "f(x)" with y: y = </span>(6x+9)/(x-5)
<span>
2. Interchange the variables x and y: x</span> = (6y+9)/(y-5)
3. Solve this result for y: x(y-5) = (6y+9), or xy-5x = 6y+9. Then:
xy-6y = 9 + 5x, or y(x-6) = 9+5x
9+5x
Then y = --------------
x-6
Here x may not = 6, because division by zero would occur otherwise.
Answer: 16
Step-by-step explanation:
if we were to list all the factors of 64 and 144
64= 1,2,4,8,8,16,32,64
144= 1,2,3,4,6,8,9,12,12,16,18,24,36,48,72,144
therefore the GCF of 64 and 144 is 16
The sum of angles in any Rhombus is 360 degrees.Opposite angles of a rhombus are congruent.
Two of the adjacent angles are 2x+20 and 50 degrees.
The opposite angles measure 2x+20 and 50 degrees.
Sum of angles in any Rectangle is 360
2x+20+50+2x+20+50=360
Adding line terms,
4x+140=360
Subtracting 140 both sides:
4x=220
Dividing both sides by 4
x=55
Option B. 55 is the right answer.
