You cannot answer this question with the information supplied.
The x intercepts are the roots of the polynomial f(x) = 0.
The fundamental theorem of algebra says that the number of roots of this equation is 9, but not necessarily all of them are real; therefore the MAXIMUM number of x intercepts is 9.
However, since f(x) is of odd degree it must have at least one real root; therefore, the MINIMUM number of x intercepts is 1.
Answer:
54
Step-by-step explanation:
Since there are parantheses or however you spell them, by using PEMDAS, we do the parantheses first.
23 - 1 = 22
Now, we do the addition.
22 + 32 = 54
6 times 2 is 12 and 15 minus 12 is 3 so three more pieces are needed.
I think this is how to do it :)
Answer:
x = 3
Step-by-step explanation:
First, multiply all four terms by 10 to eliminate the fractions:
4x - 8(x-4) = 13x - 19
Next, carry out the indicated multiplication, obtaining:
4x - 8x + 32 = 13x - 19
Combining the x terms, we get:
-4x + 32 = 13x - 19, or
32 = 17x - 19
Combining the constants, we get 51 = 17x, and so x = 51/17 = 3.
