2 and 3 look good, Mathematician.......(on 3,  I think they're assuming that he works 40 hrs. per week !!!)

4 goes like this:

Let the width = W ...then the length is 4 greater = W + 4    and we have

W (W + 4) = 96

Yes...it can be written as  78/10.....repeating and terminating decimals are always rational

For point-slope form, we have

y - y1  = m(x - x1)       where m is the slope and (x1, y1) the given point

y - (-6) = (-3/4) (x - 2)   simplify

y + 6 = (-3/4)x + 3/2      subtract 6 from both sides

y = (-3/4)x + 3/2 - 6        (6 = 12/2)

y = (-3/4)x + 3/2 - 12/2

y = (-3/4)x - 9/2

Oh, no, Ethan !!!!...Brittany's numbers ARE primes........composites would be 4, 6, 15, 28.....etc.

Ethan meant to say  "cannot"

HAHAHAHAHAHA!!!!!

I gave you a point, Ethan.....this time.....Brittany IS out of luck......!!!!

We'd have to know what the function f(x) is....whatever it is....g(x) reflects it about the x axis and shifts it up two units......

That's because 15sin(95)/9 is > 1.....no matter if 95 is in rads or degrees...thus, you're trying to find an angle whose sine > 1.......that's impossible, since the sine only returns values from -1 to 1.

6h-6+2h<2(4h-3)    simplify

8h - 6 < 8h - 6

There is no solution to this.......a quantity cannot be less than itself.....!!!
