Domain = R
Range = R .............
<span>I'd suggest you actually solve the equation. 2x+2 = 3x+1 becomes 1=x. Thus, this equation is only true for x = 1. </span>
Answer:
$218.70
Step-by-step explanation:
You need to first convert the percentage to the decimal.
20% = 0.2
Now, you need to find 20% of each bill by multiplying each bill by 0.2.
0.2(185.45) + 0.2(205.20) + 0.2(195.05) + 0.2(245.80) + 0.2(262.00)
Because of the distributive property, you can add up the bills and multiply the sum by 0.2.
0.2(185.45 + 205.20 + 195.05 + 245.80 + 262.00)
0.2(1093.50)
218.7
The waiter made $218.70 in tips.
The base is the same throughout, and is 4.
You need only combine the given exponents of 4 into one: 20+4-14+2 = 12.
Thus, the shortened expression is 4^12.
