What you would do is you would substitute each ordered pair into their respective variables. (ie. for (0,1) you would put 0 where the x is and 1 where the y is) You would then solve the equation. If the equation is not even (ie. 2=5 would not be even but 4=4 would be), you move on to the next ordered pair.
If you follow the process right and you get the equations correct, the answer should be B. (7,-2)
When you multiply exponents like in the problem, you add them together.
So to find the answer, just subtract the final exponent of 'a' from the original.
6-2=4
The answer should be 4
Answer:
0.89 as a fraction would equal: 
0.234 as a fraction would equal:
0.6 as a fraction would equal: 
You plug -3 into -2x-7 and you get B -1.
4 ⁽ˣ⁺⁵⁾ = 16 (x-3)
Simplify.
4x + 20 = 16x - 48
Subtract 16x from both sides, as well as subtracting 20 from both sides.
4x - 16x = -48 - 20
Add like terms.
-12x = -68
Divide both sides by -12
x = 5 2/3
