Answer:
7/15
Step-by-step explanation:
2 1/7 is mixed fraction, if you turn it into a improper fraction, you will get 15/7. Just flip those two numbers, and you get the answer
The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
The answer is 600 because 1 out 3 is 60 so to find the bag multiply by two while to find 1 out 5 of her monet take 60 times 3 which is 180. 180 times 4 is the money she spent on her mobile phone so take the money spent on her mobile phone(720)minus the amount of money spent on the bag(120)
Answer:
see below
Step-by-step explanation:
1.)
(0, 4)
(1, 7)

y = 3x + b
(4) = 3(0) + b
b = 4
y = 3x + 4
Rate of change: 3 initial value: 4
2.)
(0, -5)
(1, -3)

y = 2x + b
(-5) = 2(0) + b
b = -5
Rate of change: 2 initial value: -5
