Answer:
m = 3/2
Step-by-step explanation:
You want to find the slope, or the change in y coordinates over change in x-coordinates.
The first given point is E(-2, -4)
The second point is F(2, 2)
Coordinates are given in (x, y), so following the equation and computing the x and y coordinates of E - F for both the numerator and denominator:

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.
Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.
ANSWER:
- [ 12 / ( x - y ) ]
STEP-BY-STEP EXPLANATION:
= 12 / ( y - x )
= 12 / - ( x - y )
= - [ 12 / ( x - y ) ]
Let x = your number.
x^2 - 21 = 4x. Subtract 4x from both sides.
x^2 - 4x - 21 = 0. Factor.
(x - 7) (x + 3) = 0. Set each term to 0.
x + 3 = 0. Subtract 3 from both sides.
x = -3. This is the negative solution.
Set the other term equal to zero.
x - 7 = 0. Add 7 to each side.
x = 7. This is the positive solution.
Step-by-step explanation:
To find the Circumference of a triangle you use the formula C= 2(pi)r
in both of the problems you have the radius(r) and you plug the #'s in and solve
(pi)= 3.14...
#1.
2(pi)14.5
28(pi)
C= 87.92
#2.
2(pi)9.5
19(pi)
C= 56.66
