Hello! The answer is definitely not C or D, because that's way too i God an increase for this type of setting. It increased by around 20%, because when 35 and 29 are divided and you multiply the decimal by 100, when you ignore the "1" at the front, it shows an approximate 20% increase. The answer is A.
Hello!
The graph, (2/5)^x is an exponential function.
Since there is not a negative symbol in the front of the function, options A and B are incorrect.
For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.
So therefore, the answer option 4. (Also, I'll post a graph. :))
Using a system of equations, it is found that a small box of tangerines costs $10 and a large box costs $14.
<h3>What is a system of equations?</h3>
- A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the <em>variables </em>are:
- Variable x: Cost of a small box.
- Variable y: Cost of a large box.
Krystal sold 7 small boxes of tangerines and 14 large boxes of tangerines for a total of $266, hence:
Simplifying by 7:
Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:
Since :
Then
A small box of tangerines costs $10 and a large box costs $14.

Answer:
x² + 6x - 5x – 30=(x-5)(x+6)
Step-by-step explanation:
x² + 6x - 5x – 30=x²+x-30
delta=1-4(-30)=1+120=121=11²
Sqrt(delta)=11
The roots are:
x1,2=(-1 +- 11)/2
Thus we get
x1=(-1+11)/2=10/2=5
x2=(-1-11)/2=-12/2=-6
Finally:
x² + 6x - 5x – 30=(x-5)(x+6)
