Aljan and Bella are both driving from Cleveland to Chicago. Aljan leaves at

Natalija [7]

Answer:

Bella will pass Ajjan after 4h and they will have travelled 260 miles.

Step-by-step explanation:

In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,

$60*x + 20 = 65*x\\65*x - 60*x = 20\\5*x = 20\\x = \frac{20}{5} = 4$

In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:

$y = 65*4\\y = 260$

Bella will pass Ajjan after 4h and they will have travelled 260 miles.

Find the axis of symmetry and vertex of the following y= -2x2-3x+2

Mnenie [13.5K]

Y= -2x²-3x+2, (form y = ax² +b .x + c

The parabola opens downward & hence it's Vertex is a MAXIMUM.

We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125

Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
