Answer:
C) (7 , 14)
Step-by-step explanation:
Substitute each ordered pair into the equation
-5x + 3y = 7.
A) (2 , -1)
-5(2) +3(1) = -10 +3 = -7 this does not equal 7 so not true
B) (-5 , 3)
-5(-5) +3(3) = 25 +9 = 34 this does not equal 7 so not true
C) (7 , 14)
-5(7) + 3(14) = -35 + 42 = 7 this equals 7 so true
D) (-2 ,−135)
-5(-2) + 3(-135) =10+405 =415 this does not equal 7 so not true
Answer:
are u mulitplying or what?
Step-by-step explanation:
The center of the circle that circumscribe about DABC is
.
A circle can be modelled after a expression of the form:
(1)
We can determine all coefficients by knowing three <em>distinct</em> points on plane.
If we know that
,
and
, then the solution of the system of linear equations is:
(2)
(3)
(4)

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

Mountains would be a good example of this. While they do not have a straight rise, you can just take the average.
Ladders are another example. You can calculate the slope of a ladder to make sure it wont fall.
I hope this helped you understand about the uses of slopes in the real world! If this is confusing, don't be hesitant to drop a DM.
The answer to the problem is D.61/100
Hope this helps.
