Answer:
D
Step-by-step explanation:
1. The domain is all x values for the function.
2. Since the line starts at the x value of 3, it is included and since it goes to the right, it also includes all the values greater than 3.
3. Therefore, x>_3

Answer:
The actual length of the helicopter is <u>23 feet</u>.
Step-by-step explanation:
Given:
On a scale drawing, a helicopter is 2.3 feet long.
The scale on the drawing shows a ratio of 1 foot to 10 feet.
Now, to find the actual length of the helicopter.
Let the actual length of helicopter be 
.
On scale drawing length of helicopter = 2.3 feet.
The scale on the drawing shows a ratio = 1:10.
Now, as ratios are given so by setting proportion we solve it:
<em>By cross multiplying we get:</em>
⇒ 
⇒ 
⇒ 
Therefore, the actual length of the helicopter is 23 feet.
The best estimate to the nearest one percent of the fraction; 7/15 is; 47%.
<h3>What is the best estimate of the fraction to the nearest percent?</h3>
From the task content, it follows that the fraction given whose estimate is to be determined is; 7/15.
The fraction expressed as a percentage is;
(7/15) × 100 %
= 46.667%.
Hence, when rounded to the nearest one percent; = 47%.

Answer:
the equation for a line is y=MX+b
m= slope(rise/run)
x=variable
b= y intercept
you would find the slope by looking at the rise over run which are both 1 and the line is negative so the slope would be negative one
you would find b by looking at where the y intercept is (y when x is zero) which is 9
y= -x+9
hope that helped
