Answer: 121
Step-by-step explanation:
Answer:
It would be B. Fuction 1 has the larger maximum at (4,1)
Step-by-step explanation:
because the maximum point for Fuction 1 is at (4,1) becuase that the highest point/vertex it goes.
You can use a graph to identify the vertex or you can find the minimum or maximum value algebraically by using the formula x = -b / 2a. This formula will give you the x-coordinate of the vertex. Simply replace the x in your original equation with the value of the x-coordinate and then solve for y.
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
