Answer:
2x+5
Step-by-step explanation:
You double the amount she has and add 5 so it would be 2x+5
Hope this helps!
In this case, it is a (-infinity, +infinity)
In this case, y can assume any number, negative or positive, and for all values of x, the number can be squared and subtracted from
Answer: x > 75-69.95; you need five dollars and five cents more for free shipping ($5.05)
Step-by-step explanation: i believe this is the correct answer because as long as you have 75 dollars or more, then you will be good so that’s how i got the inequality. to find this you just subtract the amount needed (75) by the amount you have and you get your answer. oh and to be clear x represents the amount needed for free shipping. i am not sure if i understood the problem correctly so i apologize if it is incorrect. i hope this helped and good luck!
6x-9-2(1-x) = x-9
6x-9-2+2x = x-9 | -x
7x -11 = -9
7x = -9+11
7x = 2
x = 2/7
Answer:
Option b is correct
Step-by-step explanation:
In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:
Here we can see that highest exponent of the polynomial function is 4
therefore degree of the polynomial is 4. and therefore is leading term.
because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.
therefore option b is correct.
