Step-by-step explanation:
Answer:
k = 20
Step-by-step explanation:
t1 = a = k-4
a = k - 4
t2 = ar = k
(k-4)r = k - 4
r = k/(k-4)
t3 = ar^2 = k + 5
(k - 4)(k/k - 4)^2 = k+5
k^2/k-4 = k+5
k^2 = (k+5)(k-4)
k^2 = k^2 -4k +5k -20
0 = k -20
k =20
Answer:
-7-y1=-4(2-x1)
Step-by-step explanation:
Point slope form is like this: y-y1=m(x-x1) where y is the y value, x is the x value, and m is the slope. You plug the values in.
Should be D. F(X) = 1 over x+1
