Answer:
f^-1(x)=1/4x+2
Step-by-step explanation:
y=4x-8
change x and y
x=4y=8
switch sides
4y-8=x
add 8
4y=x+8
divide both sides by 4
y=1/4x+2
substitute f^-1(x) for y
f^-1(x)=1/4x+2
Answer:
72 alligators, 128 turtles
Step-by-step explanation:
When you put the words into the form of an equation, with a being alligators, you get
3a-16=200
So you have to do 'letters left numbers right'. This gives you
3a=216
Now you have to divide. 216 divided by 3 equals 72. So there are 72 alligators. 200 minus 72 equals 128, so there are 128 turtles
If you multiply 6 times 8, you will get 48 as final answer
9 years because if you do 4700 * 1.03= 4831 now do that 9 times you get 6,132.43
83 + 94 + 79 + 97 + 96 + 87 = 536.
536 ÷ 6 = 89.333333...
So, Lamonts' average is under 90.
