15 x 45 = 675
45 x 135 =6075
23.1 is the answer. Have a great day!
Answer:
Have 2 boxes, and fill one of them
Answer:
66 in
Explanation:
the circumference can be calculated as:
Where d is the diameter and π is 22/7.
So, replacing the values, we get:
Therefore, the circumference is 66 in.
Answer:
(c) y = -3x +6
Step-by-step explanation:
The equation can be written in slope-intercept form when we know the slope and the y-intercept.
<h3>Slope-intercept form</h3>
The slope-intercept form of the equation of a line is ...
y = mx +b . . . . . . where m is the slope and b is the y-intercept
<h3>Y-intercept</h3>
The y-intercept is the y-value where the line crosses the y-axis. It is 6. This eliminates choices A and D, leaving choices ...
- y = 3x +6 . . . . . choice B
- y = -3x +6 . . . . .choice C
<h3>Slope</h3>
The line goes down to the right. This is a negative slope, eliminating choice B.
The equation of the line is y = -3x +6.

<em>Additional comment</em>
The line intersects the x-axis at x=2. This means the "rise" of the line is -6 units for a "run" of 2 units. The numerical value of the slope is ...
m = rise/run = -6/2 = -3
Now, we know the parameters of the equation are m=-3, b=6, and the equation of the line is
y =-3x +6
