f(5) is -1
Step-by-step explanation:
- Step 1: Given f(x) = -2x + 9, find f(5)
f(5) = -2 × 5 + 9 = -10 + 9 = -1
Find the inverse, interchange the variables to solve for y
f-1 (x)=-
![\frac{8- \sqrt[]{_2(-8+x)} }{2} ,](https://tex.z-dn.net/?f=%20%5Cfrac%7B8-%20%5Csqrt%5B%5D%7B_2%28-8%2Bx%29%7D%20%7D%7B2%7D%20%2C)
Answer:
-5
Step-by-step explanation:
10 minutes 15 equals -5
8/11--------> 16
to find the total number of fish, divide 16 by 8 and multiply it by 11,
16÷8=2
2×11=22
total number of fish= 22
check,
22÷11×8=16
if you want to find the number of fish without the red stripes,
8/11--------> 16
11/11------->22
3/11--------->?
you can either subtract 16 by 22=6
or
22÷11×3=6
hope this helps......
