First, you have to split 56 in half (because Lena bought 4 more than half of 56) 56 divided by 2 equals 28. Then you add 4 because again, Lena bought 4 more than half. That ends up at 32.
To find Jodie's bottles, you have to do 56 - 32, because the remainder of the bottles belongs to Jodie. I got 22.
Jodie bought 22 bottles of nail polish.
Answer:
Option C. 2x + 20 / x² + 6x – 40
Step-by-step explanation:
f(x) = x + 16 / x² + 6x – 40
g(x) = 1 / x + 10
To find f(x) + g(x), please refer to the attached photo.
Answer:
f(½) = 1.73
f(¼) = 1.32
Step-by-step explanation:
You will find the complete question attached as a picture alongside the solution.
y = f(x) = 
When f(x) ⇒ f(½); that is, x = ½
y =
= 
y = 1.7320508076 ≈ 1.73
y = <u>1.73</u> (to the nearest hundredth)
When f(x) ⇒ f(¼); that is, x = ¼
y =
= ![\sqrt[4]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B3%7D)
y = 1.316074013 ≈ 1.32
y = <u>1.32</u> (to the nearest hundredth)
Equal ratios are those that are equal to each other.
Example:-
4/2 = 8/4
Also, ratios compare to values, and there are 3 ways to write a ratio.
4/2 and 4:2 and 4 to 2
Answer:
