We have a function f(x) defined below:
f(x) = (4x²-36x)/(x-9)
We can factor the top:
f(x) = (4x)(x-9)/(x-9)
We see an (x-9) term in the top and bottom. This means that we can reduce f(x) down to:
f(x) = 4x
But we must keep in mind that due to the canceling (x-9) terms, there is a <em>removable discontinuity (hole) at x = 9</em>
To find the zeros of f(x), simple set f(x) = 0 and solve for x:
f(x) = 4x
0 = 4x
x = 0

3/4 ÷ 5/8
Keep Change Flip
3/4x8/5
=6/5
Hope this helps :)
Answer:
765
Step-by-step explanation:
Craig picks 4 times 459 apples, or 1836 apples. The total number Lori and Craig picked is ...
total apples = 459 +1836 = 2295
Each of the three equal groups will have 1/3 this number of apples, so will have ...
1/3 × 2295 = 765 . . . apples
There are 765 apples in each group.
Step-by-step explanation:
You can use a ratio for this:
So if you multiply 80 × 5, the divide by 1, you will get your answer.
133
Solution
x2 -3xy
=(-7)2- 3x(-7) x 4
=49 + 21 x 4
=49 + 84
=133
Note: I put 2 instead of the “mini 2” or squared cuz I cant copy and paste it lol
