Answer:
21.43 miles
Step-by-step explanation:
Let
x ---> the number of miles
y ---> the total cost of rent a car per day
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
<em>sunshine rental company</em>
The slope is equal to
The y-intercept is equal to
substitute
----> equation A
<em> rent me company</em>
The slope is equal to
The y-intercept is equal to
substitute
----> equation B
equate equation A and equation B
solve for x
He would walk 3/10 x7 so that would be 21/10 simplify that will be 2 1/10
<span>y=a((x-h)^2)+k
Vertex=(h,k)
1. Vertex (5,-1) Point (2,4)
y=a((x-5)^2)+(-1)
f(2)=4
4=a((2-5)^2)+(-1)
4=a(-3)^2-1
4=a*9-1
5=a*9
5/9=a
y=(5/9)((x-5)^2)-1
2. Vertex (-2,0) Point (-1,-7)
y=a((x+2)^2)+0
y=a((x+2)^2)
f(-1)=-7
-7=a(-1+2)^2
-7=a(1)^2
a=-7
y=-7(x+2)
(x-h)^2=4(d)(y-k)
3. Vertex (0,0) Focus (0,2)
d=f-v
d=2
(x^2)=4(2)(y)
(x^2)=8y
f(0)=0
4. Focus (-3,4) Directrix y= -2
(x-h)^2=4(d)(y-k)
d=(4-(-2))/2=6/2=3
(x-h)^2=4(3)(y-k)
h=-3
k=(-2+4)/2=(2)/2=1
(x+3)^2=4(3)(y-1)
(x+3)^2=12(y-1)</span>
