Because we have x = 3, we can substitute it. But first, let's convert 2x + 4y = 14 into y-slope intercept form.
2x + 4y = 14
Subtract 2x from both sides.
4y = -2x + 14
Divide both sides by 4.
y = -1/2x + 3.5
Now substitute.
y = -1/2(3) + 3.5
y = -1.5 + 3.5
y = 2
(3, 2)
4+I-15I÷3
4+15÷3
4+5
9
The answer is 9
The correct answer is definitely C.
A reasonable estimate is an educated guess made by an observer based on that person's current knowledge and following observations. For example, If Garth knew that he was 1.2 meters tall, and he observed that the door was approximately twice his own height, Garth could then make the reasonable estimate that the door is about 2.4 meters tall.
