Vertex = (0, 0)
focus = (-2, 0)
p = -2 - 0 = -2
Required equation is (y - k)^2 = 4p(x - h); where (h, k) = (0, 0), the vertex
(y - 0)^2 = 4(-2)(x - 0)
y^2 = -8x
Required equation in standard form is x = -1/8 y^2
Use the slope 9 and then go through (0,0)
So first divide 420 by 3 which gets you 140 so now you need to divide that 140 by 20 which is 7 so the jeweler could make 7 necklaces which is B. If you have any questions just ask. Hope I helped you ❤️
Answer:
A
Step-by-step explanation:
For test A, the unit rate is 30 words per minute divided by 4 minutes, or 7.5 words per minute.
Unit rate = 78 words/15 minutes = 5.2 words per minute for test B.
The unit rate for test C is 99 words/22 minutes, or 4.5 words per minute.
15 pounds each and 16 watermelons= 240 pounds. (15x16=240)
