Answer:
A.) 1/81
Step-by-step explanation:
This is your equation:
f(x) = 9^x
They want you to solve for x = -2, so substitute -2 in for x.
f(-2) = 9^-2
When you solve this, you get, 1/81.
So, the answer is A.)
I hope this helps! :)
If green= ripe then 20 are ripe
So if p then q
the converse is if q then p
so
if x is odd then 2x+1 is odd
converse is
if 2x+1 is odd, then x is odd
4th option
Answer:
55° because 2and 6 are corresponding angles (they are equal)
6 and 8 are vertically opposite angles (they are equal)

Answer:
y = 2.31x + 309.35
Step-by-step explanation:
Whenever you are checking for a best fitting equation you want to check if it has a constant slope. If it does then the relation is linear and super easy.
So, since the t values are increasing by the same amount you want to see if the y values are too. And they are, each population entry is increasing by 2.31, this is the slope.
Also, keep in mind you can caluclate slope with the equation
here x is replaced by t though.
Now, since we know it's linear and we know the slope we can find the equation with the formula y - y1 = m(x - x1) where again, x is replaced by t and m is the slope 2.31
I am just going to use the first point. so x1 = t1 = 0
y - 309.35 = 2.31(x-0)
y = 2.31x + 309.35
Let me know if there was something you didn't understand.
