Answer:
Step-by-step explanation:
First you add 4 on both sides
X^2=0
Then you take square on both sides
X=+- the square root of 4
Simplify that
X=plus or minus 2
The answer can be either -2 or +2 (which is just 2)
Answer:
D. 25%
Step-by-step explanation:
f(x) = 2 * (1.25)^x
This is in the form
y = a b^x
where b is 1 plus the growth rate
b = 1.25 = 1+growth rate
1.25 = 1 + growth rate
.25 = growth rate
25% = growth rate
<h3>
Answer: $1.26 </h3>
=======================================================
Work Shown:
2.25% = 2.25/100 = 0.0225
2.25% of 56 dollars = 0.0225*56 = 1.26
The amount of sales tax is $1.26
Side note: The total bill is 56 + 1.26 = 57.26 dollars.
