$\sf (6x^2-6x-4)-(5x^2-8x-4)$

Distribute -1 in the 2nd parenthesis:

$\sf 6x^2-6x-4-5x^2+8x+4$

Combine like terms:

$\sf 6x^2-5x^2=x^2$

$\sf -6x+8x=2x$

$\sf -4+4=0$

So we have:

$\sf x^2+2x$

The dot plot that was illustrated simply shows that the airline's flights had shorter flight times is Airjet Express.

It should be noted that a dot plot simply means a plot that is used to display the data values.

In this case, the dot plot that was illustrated simply shows that the airline's flights had shorter flight times is Airjet Express. This was depicted in the data visualization.

A dartboard has a diameter of 4 inches. What are its radius and circumference? Round to

arlik [135]

Answer: The radius is 2 inches.

The circumference is approximately 12.56 inches.

Step-by-step explanation:

Given : The diameter of a dartboard = 4 inches

Since , radius is half of the diameter.

Therefore, radius of dartboard = (diameter) ÷ 2

= (4 inches ) ÷ 2 = 2 inches

Also, Formula for circumference : $C=2\pi r$ , where r is radius.

Now , Circumference of dartboard = $2(3.14)(2)=12.56\text{ inches}$

Hence, The radius is 2 inches.

The circumference is approximately 12.56 inches.

What is the equation of the line?

Oksi-84 [34.3K]

First find the slope of the line. Slope is defined as the change in y over the change in x.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Find two ordered pairs and plug them into the slope formula.

After looking at the graph, I found two points: (0, 1) and (4, 4)

$\frac{4 - 1}{4 - 0} = \frac{3}{4}$

Now find where the line intersects the y-axis.

After looking at the graph, I found out that the line intercepts the y-axis at
(0, 1)

Now build the slope-intercept equation.

General form: y = mx + b
Where m is the slope and b the y-intercept

So, the answer is y = 3/4m + 1
