Answer:
The slope is -4
Step-by-step explanation:
hope this helps
(-7,21),(-6,17)
17-21/(-6)-(-7)
=-4/1
= -4
(-5,13),(-4,9)
9-13/(-4)-(-5)
=-4/1
= -4
Answer:
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
Step-by-step explanation:
350 = 12(x + 20)
Multiply out brackets: 350 = 12x + 240
Subtract 240 from both sides: 110 = 12x
Divide both sides by 12: 9 1/6 = x
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
The points of the circle satisfy the equation
.. (x -1)^2 +(y -5)^2 = r^2
Filling in the given information, we can find r^2.
.. (10 -1)^2 +(10 -5)^2 = r^2
.. 81 +25 = r^2 = 106
The area of the circle is
.. A = πr^2 = 106π ≈ 333 . . . . square units
