Answer:
115 are not minivans.
Step-by-step explanation:
So, every for every 2 minivans, there are 5 other types of vehicles.
In other words, out of 7 vehicles, 2 are minivans.
In a fraction, this is 2/7.
To find the number of minivans given 161 total vehicles, we can write a proportion. So:
We need to solve for x. Cross multiply:
Divide both sides by 7:
So, given 161 total ehicles, 46 of them are minivans.
This means that 161-46 or 115 are not minivans.
So, our answer is 115.
And we're done!

Answer:
B. y=3(x-1)2 + 3
Step-by-step explanation:
Given that
vertex of the parabola is at the point (1,3)
let's verify, if the option B is the correct equation of the parabola.
comparing to standard equationof parabola (standard quadratic equation), we get
to find the vertex we use formula for x- coordinate as
to find y put x=1 in the Eq1, we get
vertex =(x,y) = (1, 3)
thus vertex of the parabola from the equation y=3(x-1)2 + 3 is (1,3), thus verified
