Answer:
by using the graph!
Step-by-step explanation:
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.
I was taught to get a common denominator and then arrange them in the correct order.
So first you find out what all the denominations can be multiplied to. That would be 40
So you multiply the bottom of each fraction by a number that will get 40.
3/4 * 10 = 30/40
7/8 * 5 = 35/40
3/5 * 8 = 24/40
Then you get 30/40, 35/40, and 24/40.
Then you organize the m.
24/40, 30/40, and 35/40
Answer 1.)is 196 simplify 7^2 to 49 6*(49-15)-2^3. Do 49-15=34 6*34-2^3. Do 2^3 to 8 6*34-8 =204-8 which is 196 hope this helps you
He needs to learn >10 new plays, but has already learned 4. Therefore, the inequality is x+4>10, where x is the amount of new plays he must learn, 4 is the amount he has already learned and >10 (more than 10) is the amount of plays he needs to learn in total.
x+4>10
x>6 is the solved inequality
