Why do whole numbers with an exponent get bigger while fractions with an exponent get smaller.
ohaa [14]

Raising a whole number to a power means: 

             Take (a number of things) a number of times, and then possibly
             take that big number of things a number of times again.

Raising a fraction to an exponent means: 

             Take a piece of (a piece of one thing), and then possibly
              take just a piece of that smaller piece.

Use substitution to solve each system of equations <br> Y=2x-2<br> Y=x+2
Alik [6]
Y = 2x - 2 ⇒ 2x - y = 2  ⇒ 2x - y = 2
y = x + 2  ⇒ x - y = -2   ⇒ <u>2x - 2y = -4</u>
                                                 <u>3y</u> = <u>6</u> 
                                                  3     3
                                                   y = 2
                                            2x - 6 = 2
                                            <u>      +6   +6</u>
                                                 <u>2x</u> = <u>8</u>
                                                  2     2
                                                   x = 4
                                             (x, y) = (4, 2)
