Answer:
14
Step-by-step explanation:
Order of operations rules require that we do any work inside parentheses first. Thus,
–(31 + 2) + 72 – (–5)^2
becomes:
-33 + 72 - 25, or
14
Important: Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.
The ordered pairs of the equation y = 3^x are (0,1), (1,3) and (2,9)
<h3>How to type the ordered pairs?</h3>
The equation is given as:
y = 3^x
Let x = 0, 1 and 2
y = 3^0 = 1
y = 3^1 = 3
y = 3^2 = 9
So, we have the following ordered pairs (0,1), (1,3) and (2,9)
Hence, the ordered pairs of the equation y = 3^x are (0,1), (1,3) and (2,9)

It will take Alexis 5 weeks. If she starts off with $50, she will still need $150. Then, she earns $30 each week every week. Making $30 for 5 weeks will get Alexis to $150, because 30×5 is 150. Then once you add in the money she started with you will get $200. $150+$50=$200.
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
