Set it up algebraically
3 times a number so 3x where x = the mystery number
times 7 so 3x*7
and it equals 63 so,
3x*7=63
this can be further simplified to
21x=63
then just divide both side by 21 to get your answer
(21/21)x=(63/21)
so x=3
Answer:
x=6
Step-by-step explanation:
First subtract x on both sides. And you will have x+4+2x=10.
Second you subtract the x to the 2x,it wil equal to 4+x=10.
Third subtract 4 on both side.
It will equal you to x=6
Answer:
-1.25
Step-by-step explanation:
The result can be shown in multiple forms. Exact Form: 385 38 5. Decimal Form: 7.6 7.6. Mixed Number Form: 735 7 3 5. 385 3 8 5 .
Answer: The answers are
(i) The local maximum and local minimum always occur at a turning point.
(iii) The ends of an even-degree polynomial either both approach positive infinity or both approach negative infinity.
Step-by-step explanation: We are given three statements and we are to check which of these are true about the graphs of polynomial functions.
In the attached figure (A), the graph of the polynomial function 
is drawn. We can see that the local maximum occurs at the turning point P and local minimum occurs at the turning point Q. Also, the local maximum is not equal to the x-value of the coordinate at that point
Thus, the first statement is true. and second statement is false.
Again, in the attached figure (B), the graph of the even degree polynomial 
is drawn. We can see that both the ends approaches to positive infinity and in case of 
, both the ends approch to negative infinity.
Thus, the third statement is true.
Hence, the correct statements are first and third.
