your friends final bowling score is 105. your final bowling score is 14 pins less than your friends final score write and solve an equation to find your final score

Answers

Let your final bowling score be x. It is 14 pins less than your friends final score. Your friends final bowling score is 105. Then x is 14 pins less than 105.

1 way: This means that 105 is greater than x by 14. Mathematically,

105-x=14,

-x=14-105,

-x=-91,

x=91.

2 way: When you add 14 to x, you'll get 105.

x+14=105,

x=105-14,

x=91.

Answer: Your final score is 91.

You could use x to represent your friend's score and y to represent your score. So if your score, y, is 14 less than your friend's score, x, then the equation would be:
 x-14=y.
Now you plug in the x, 105, and solve for y.
105-14=91

Consider the function f(x)=2x^3+24x^2−54x+9,−9≤x≤2 This function has an absolute minimum value equal to? and an absolute maximum value equal to ?

Answers

If you evaluate it, it's −9≤x≤2 and trying to find the absolute maximum/minimum of it then you'll get nothing due to it being an improper fraction of some sorts.. And there's still nothing when trying to find it all together.. Sorry that I wasn't that much help.
