F(3)= 2(3)^2-5(3)+9
=2(9)-15+9
=18-15+9
=3+9
=12
f(3)=12 or B
Answer:
There are 1766 chipmunks in the population
Step-by-step explanation:
Number of individuals increasing per year = 265
Rate of increase = 0.15
Rate of increase = increase in number of individuals in a given population /total population
Substituting the given values, we get -
0.15 = (265/total population)
Total population = 265/0.15 = 1766
<u>1 + 4x = -5 + 7x</u>
1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:
1+5=7x-4x
2nd step:
3x=6
3rd step: you need to divide both sides into 3, because it is the common divisor.
x=2
<h2>
To sum up:</h2>
<em>1 + 4x = -5+7x</em>
<em>7x - 4x = 1 + 5</em>
<em>3x = 6</em>
<h2>
<em>x = 2</em></h2>
You can try to memorize the summary. However, it is better to understand the solution as a whole.
The slope of the line in the function is 1
<h3>Slope of Line</h3>
The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
m = y₂ - y₁ / x₂ - x₁
Taking two points;
Substituting the values into the formula;
m = -2 - 0 / 3 - 5
m = -2 / - 2
m = 1
The slope is calculated as 1
