Answer:
x-intercept=(-1,0) y-intercept =(0,-3)
Step-by-step explanation:
The unit rate will be in revolutions per second. That means divide number of revolutions by number of seconds.
first convert from mixed fraction.
6 2/5 = 32/5 revolutions
2 2/3 = 8/3 seconds
32/5 ÷ 8/3
flip multiply
32/5 × 3/8 = 12/5 revolutions per second
12/5 = 2 2/5 revolutions per second
70). Answer Letter Choice, (C), 18 pi square units.
Area = pi r^2
D = 12
R = 6
Larger Circle: 36 pi
Find smaller circles, Subtract:
Diameter of larger circle is 12
Radius 6, also diameter of small circles (2)
pi r^2
D = 6
R = 3
pi = 9
2 circles
2 * 9 pi = Letter Choice, (C), 18 pi square inches

<h2>Steps:</h2>
(Let x = greater number and y = lesser number)
So this question is asking us for a system of equations. Using the info they provide, we can form these two equations:
So for this, we will be using the substitution method. Since we know that x = y + 7, substitute x with (y + 7) in the second equation as such:
From here we can solve for y. Firstly, distribute 3 so that it multiplies with y and 7:
Next, subtract 3y on both sides of the equation:
Lastly, subtract 5 on both sides of the equation:
Now that we know the value of y, we can substitute it into either equation to solve for x:
<h2>Answer:</h2>
<u>In short, 16 is the lesser number and 23 is the greater number.</u>
