79% = 0.79= 79/100
(not sure if this is what you meant?)
Answer:
x=a/(y-k)+h
Step-by-step explanation:
y-k=a/(x-h)
(y-k)(x-h)=a
xy-hy-kx+kh=a
xy-kx=a+hy-hk
x(y-k)=a+h(y-k)
x=a/(y-k)+h
9:00 to 3:45 = 6 hours 45 min
1 lesson = 55 min
6 lessons = 5 hours 30 min
5.3 + 0.25 = 5 hours 55 min
6.45 - 5.55 = 50 min
lunch = 50 min
Answer:
a) (-2,-8)
b) not sure :(
c) (0,-4)
Step-by-step explanation:
To find the vertex rewrite in vertex form and use this form to find the vertex (h,k). To find the y-intercept, substitute in 0 for x and solve for y.
