Answer:
y = 2
Step-by-step explanation:
If someone gives you an function that says f(x) = x + 2, that is the same thing as saying y = x + 2. The f(x) part is just to represent that it is a function of x.
Notice how 1/2 and 3/8 are positive numbers. We add two positive numbers meaning that the result should be larger. However 2/5 = 0.4 is not larger than 1/2 = 0.5
So something went wrong with the adding. It turns out that the error is when the person added the numbers in the denominators (2 and 8 to get 10). This is not allowed. The denominators must be the same and stay the same in order for the fractions to be added.
For example: 1/7 + 2/7 = (1+2)/7 = 3/7
The 7s in the denominator do not change
Therefore the answer is choice B) Not true because 2/5 < 1/2
Each term of the factors must be arranged in each column of the square box. The resulting factored form of the expression is (5x+2)(2x-1)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 10x² -x - 2
Factorize
10x² -x - 2
10x² - 5x + 4x - 2
5x(2x-1)+2(2x-1)
(5x+2)(2x-1)
Each term of the factors must be arranged in each column of the square box.

Answer:
15
Step-by-step explanation:
Apply absolute rule: | a | = a, a ≥ 0
| 13 | = 13
= 13 + | -2 |
| -2 | = 2
= 13 + 2
= 15
11,132.15 thats your answer because 15 tents go after the point
