Answer:
C
Step-by-step explanation:
Observing that <em>f</em> has to be placed inside <em>g</em>, we can easily substitute x^2 - 3 in place of the x in x + 1, making it
(x^2 - 3) + 1 which equals
(x^2) - 2
The distance between the center and any point on the circle is the radius. That's likely what your book or teacher is asking for.
Note: double the radius and you get the diameter
63.27 % of fishes are gold fish
<h3><u>Solution:</u></h3>
Given that out of 49 fish, 31 are goldfish
To find: percent of gold fish
The percent of gold fish is calculated by dividing number of goldfish by total number of fish multiplied by 100
<em><u>The percentage of gold fish is given by formula:</u></em>

From given information,
total number of fish = 49
number of gold fish = 31
Substituting the values in formula, we get

Therefore, approximately 63.27 % of fishes are goldfish
<u>Answer</u>:
Linear equation.
<u>Explanation</u>:
It is linear as y increases 11 grids with every increase in x grid.
OR,
I will make a linear equation from two coordinates: (1,11),(2,22)
slope:
→
→

the find equation using:
y - y1 = m(x - x1) → y - 11 = 11(x-1) → y = 11x ....this is linear equation.
Therefore it's linear.
OR,
Then check if 3rd and 4th coordinate matches the equation.
y = 11x y = 11x
y = 11(3) y = 11(4)
y = 33 ...therefore matches y = 44...therefore matches
So, its a linear equation.
There are any number of ordered pairs that work for this equation. Below are some examples.
(0, -18) (2, -10) (5, 2)
In order to find these and any others, you simply select a value for x and plug into the equation to find y. Below is an example.
y = 4x - 18
y = 4(0) - 18
y = 0 - 18
y = -18
(0, -18)
