Answer: slope = 3
Step-by-step explanation:
We can see from the point intersecting the y axis (y-intercept) to the point (1, 1) it goes up 3 and right 1 giving us the slope 
simplified to 3
Answer:
Radius = r = 7.5
Diameter = d = 15
Circumference = C = 15π
Step-by-step explanation:
We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.
Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.
Circumference of the circle = C = 2πr
Using the value of radius(r), we can write the circumference as:
C = 2π(7.5) = 15π
Answer: 4
Step-by-step explanation: 7+-3 = 4
Answer:
-1
Step-by-step explanation:
8+9=17
9+8=17
17-8=9
17-9=8
But, 8-9 is -1
Answer:
4) 96°
Step-by-step explanation:
Supplementary angles add up to 180.
So 180-84=96
