Direct Variation. Since k<span> is constant (the same for every point), we can find </span>k<span> when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x , and y = 6 when x = 2 , the constant of variation is </span>k<span> = = 3 . Thus, the equation describing this direct variation is y = 3x .</span>
Answer:
73
Step-by-step explanation:
If you are to use Order of Operations, which most people know as PEMDAS, you come up with the following answer.
I will show my work below. Refer to it if you need to.
4x^2+5^2
16x+25
x=3, so 48 + 25
73
