Answer:
I would say y= -4x + 3 but since they said with the y-intercept of 0 then it'll become y= -4x.
Step-by-step explanation:
A. 49.3 (I hope I’m not too late)
Answer:
Step-by-step explanation:
8.
slope=(83-3)/(10-0)=80/10=8
y-3=8(x-0)
y=8x+3
when x=20
y=8(20)+3=163
243=8x+3
243-3=8x
8x=240
x=240/8=30
when x=40
y=8*40+3=320+3=323
9.
(0,8) and (5,6)
m=(6-8)/(5-0)=-2/5=-0.4
y-8=-0.4(x-0)
y=-0.4x+8
Answer:
0.06x + 0.15y = 69.84
x = (69.84 - 0.15y) / 0.06
y = (69.84 - 0.06x) / 0.15
x + y = 852
((69.84 - 0.15y) / 0.06) + y = 852
y = ?

Answer:
The length of the focal width of the parabola is 1.
Step-by-step explanation:
Suppose we have a parabola with the following equation:
The centre is at point .
The length of the focal width is of |4p|.
In this question:
We want to place in the general format. So
Comparing, we have that 4p = 1. So the length of the focal width of the parabola is 1.
