I assume that this is :

y = (x + 5)^2   - 1

The verrtex is (-5, -1)

The axis of symmetry is x  = -5

Here's the graph :   https://www.desmos.com/calculator/tk4kdyzjof

Each time the wheel rotates, it travels pi*(34 in) = about 106.81 in

And in one minute, it travels 30 * 106.81 in = about 3204.3 in

And in one hour ......it travels   3204.3 *60  = 192,258in

And there are  5280*12 = 63,360 in in one mile......so.....

192,258 / 63,360  =  about 3.03 mph

Let Bonnie's  current age = x.....and Shelby's =  7x

And in 5 years, we have

[ x + 5 ] + [ 7x + 5 ] = 98      simplify

8x + 10  = 98      subtract 10 from both sides

8x  = 88       divide both sides by 8

x = 11  = Bonnie's current age

This is way easier than it seems, at first glance

Note that we can write  this  [ using the log property    ....  loga^b  = b * log a ]  as :

[2x ] * log₃ 3 = 14     but log₃ 3   is just  "1".....so we can ignore it.......and we have

2x   = 14       and    it should be obvious that  x = 7

Even my secret decoder ring fails me, here......!!!!!

[This looks like a case for Sir LA-Tex ........!!!!! ]

Although this may not be technically correct, I'm using the conversion of 1 Q  = 4 cups

 And the number of 1/2 cups =

[12 *4] / [1 / 4]   = 192

Taking the secant inverse of (4.5600039),   the angles are about 77.33°  and  [ 360 - 77.33]°  = about 282.67°

2(4-36) divided by -12

2 (-32) / -12  =

-64 / - 12  =    the negatives "cancel"

64 / 12  =

16 / 3

-7.7=-1.3+y/4    multiply each term by 4

-30.8  = -5.2 + y     add 5.2 to both sides

-25.6  = y

1/cos(x)-cos(x)/sin(x)+1=0   we can simplify this as :

sec(x) - cot(x)  +  1 = 0

Here's the graph [ in degrees] ..........https://www.desmos.com/calculator/qoyb0nuhmr

It looks like this is true at about  [ 25.4  + 360n]°  and at about [ 125.6 + 360n]° ...... where n is some integer
