What are the x and y intercepts for this equation y=−1/4x+2?<br> (_,_)
Firdavs [7]

Answer:

(8, 0) is the x-intercept

(0, 2) is the y-intercept

Step-by-step explanation:

The y-intercept = 2 since the equation is in slope-intercept form.

The x-intercept occurs when y = 0

So,   0 = -1/4x + 2

        0 = -x + 8

         x = 8

(8, 0) is the x-intercept

(0, 2) is the y-intercept

What is the mean of Variable B?
kherson [118]
Okay, for variable B you have the data points:
1, 2, 3, 5, 6, 6, 7, 7, 10, and 10. 
What you need to do to find the mean (or average) is add all the data up and divide by how many pieces of data you had. So, the sum of all the points is 57. There are 10 points overall.
57/10 is 5.7
Your average for variable B is 5.7

Find area of shaded regions ​
emmasim [6.3K]

Answer:

38.5 cm^2

Step-by-step explanation:

Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)

= Area (large semicircle) - area (small circle)

= π(7)² x 1/2 - π(7/2)²

22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2

= 77 - 38.5

= 38.5 cm^2
