Answer: the rate of change is 1/2

Step-by-step explanation:

The formula for slope is y2 - y1/ x2 - x1

I picked points (2,2) (x1 & y1) and (6,4) (x2 & y2)

4 - 2 = 2

6 - 2 = 4

2/4 is the rate of change, and 1/2 is 2/4 simplified

Answer:

\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0\)

Step-by-step explanation:

Given quadratic equation:

\(ax^2 + (2a + 2)x + a + 3 = 0\)

To find the possible values of "a" such that the given equation has two roots and the distance between them on the number line is greater than 1, use the quadratic formula.

\(\boxed{\begin{minipage}{4 cm}\underline{Quadratic Formula}\\\\$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$\\\\when $ax^2+bx+c=0$ \\\end{minipage}}\)

Comparing the coefficients:

Substitute the coefficients into the quadratic formula:

\(x=\dfrac{-(2a+2) \pm \sqrt{(2a+2)^2-4a(a + 3)}}{2a}\)

Simplify the discriminant (the part under the square root sign):

\(x=\dfrac{-(2a+2) \pm \sqrt{-4a+4}}{2a}\)

Factor out 4 from the discriminant:

\(x=\dfrac{-(2a+2) \pm \sqrt{4(-a+1)}}{2a}\)

\(\textsf{Apply the radical rule:} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}\)

\(x=\dfrac{-(2a+2) \pm \sqrt{4}\sqrt{-a+1}}{2a}\)

Therefore:

\(x=\dfrac{-(2a+2) \pm 2\sqrt{-a+1}}{2a}\)

Factor out the common term 2:

\(x=\dfrac{-(a+1)\pm \sqrt{-a+1}}{a}\)

Therefore, the two solutions are:

\(x=\dfrac{-a-1+\sqrt{-a+1}}{a},\;\;x=-\dfrac{a+1+\sqrt{-a+1}}{a}\)

As both solutions have "a" as their denominator, a ≠ 0.

Note: When substituting a = 0 into the original equation, we are left with a linear equation, which only has one root. Therefore, this confirms that a ≠ 0.

Now we have found expressions for the two roots, we can set the distance between them to greater than 1:

\(\dfrac{-a-1+\sqrt{-a+1}}{a}-\left(-\dfrac{a+1+\sqrt{-a+1}}{a}\right) > \:1\)

\(\dfrac{-a-1+\sqrt{-a+1}}{a}+\dfrac{a+1+\sqrt{-a+1}}{a} > \:1\)

Simplify:

\(\begin{aligned}\dfrac{-a-1+\sqrt{-a+1}+a+1+\sqrt{-a+1}}{a}& > 1\\\\\dfrac{2\sqrt{-a+1}}{a}& > 1\\\\2\sqrt{-a+1}& > a\\\\(2\sqrt{-a+1})^2& > a^2\\\\4(-a+1)& > a^2\\\\-4a+4& > a^2\\\\a^2+4a-4& < 0\\\\(a+2)^2-8& < 0\\\\(a+2)^2& < 8\end{aligned}\)

\(\textsf{For\;\;$u^n < a$,\;\;if\;$n$\;is\;even\;then\;\;$-\sqrt[n]{a} < u < \sqrt[n]{a}|$:}\)

\(-\sqrt{8} < a+2 < \sqrt{8}\)

Therefore:

\(-\sqrt{8} -2 < a < \sqrt{8}-2\)

\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2\)

So the possible values of "a" such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1 are:

\(\large{\boxed{-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0}\)

x = the number of inkjet printers at the company

Y= the number of laser printers

Answer: It is below with explanations on how to do it! :D

Step-by-step explanation:

1. First one shows a graph and a line. Remember, the equation for this is y = mx + b. The point that crosses the y-axis is 0. So far, the equation looks like this: y = mx + 0. In order to find the slope, we have to choose another point on the graph. I will choose the point (-4, -2). The slope is the direction of the line travelling from left to right. So to get from (-4, -2) to the point 0, aka origin, we have to go up 2 units and move 4 units to the right. This method is called rise over run. Now the slope is 2 over 4 -> 2/4.

Final answer is y = 2/4x + 0

Simplified version is y = 1/2x + 0

That is your equation in slope intercept form!

2. The second one shows a graph and is asking to write an equation in slope-intercept form. Here is the equation for that -> y = mx+b

M is the slope, and b is the y-intercept (where the point crosses the line on the y-axis).

So, in this case, M=4 and b=0

Plug it into the equation, y = 4x + 0

The graph is attached below (I did not draw it but I took a screenshot from a video that shows it)

I also attached the graph for you for the last question!

I hope this helps you :)

Answer: I think it's P(1 win and 2 losses)

Step-by-step explanation: That is most accurate because there are 3 games, and you can't split 3 in half. (Well you can but then it would equal 1.5 and you can't win or lose a game 1.5 to 1.5). So splitting 3 is most accurate if you do 2 for 1 and 3 for another.

Hope this helps  : D

I'm not sure I can make a rectangle in a coordinate that ranges from +5 to -5 and get the area of the rectangle to be 36 squared units.

I am very sorry.

Step-by-step explanation:

Answer: Perimeter of the shape,

Answer:

The Range Stays 48°.

Step-by-step explanation:\

Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.

Hope this helps!

Answer:  B.  The range stays 48

Step-by-step explanation:

The largest answer is 105 and the smallest answer is 57.  The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest

Range = 105 - 57

Range = 48

The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.

So answer is B. The range stays 48

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)
