Question

Which output has the greatest value when the input is 5 for the following equations?

A. y = 9x
B. x + 9 = y
C. 8x = y
a) A
b) B
c) C
d) All have the same output

Answer 1

When the input is 5, equation A (y = 9x) gives the greatest output, which is 45. Hence, the answer is option a) A.

Step-by-step explanation:

The question asks which of the three given equations, when the input is 5, will produce the greatest output. To find the answer, we need to calculate the value of y for each equation with x equal to 5.

• For equation A (y = 9x), when x is 5, y will be 9*5 = 45.
• For equation B (x + 9 = y), when x is 5, y will similarly be 5 + 9 = 14.
• For equation C (8x = y), when x is 5, y will be 8*5 = 40.

Comparing the values of y for each equation, we see that A produces the greatest output of 45. Therefore, the answer to the question is a) A.
