Since the first line passes thru the origin, you can read off its slope from the coordinates of the other point (3,2): the slope is m = 2/3.

A line perpendicular to the first has slope -3/2, the negative reciprocal of 2/3.

Thus, the perpendicular line is y = (-3/2)x + b. Subbing 0 for y and 0 for x, we get b = 0. Therefore, the equation of this new line is y = (-3/2)x.

Answer:

The bottom question is wrong. You have to multiply 8 to get the amount earned. But the rest is correct.

Step-by-step explanation:

12.5 x 8 = 100

18.75 x 8 = 150

25 x 8 = 200

31.25 x 8 = 250

Answer:

Because f(g(x)) = g(f(x)) = x, f and g <u>are </u> inverse functions.

Step-by-step explanation:

f(g(x)) = f( $\frac{1}{4}\sqrt{x}$ ) = $16(\frac{1}{4}\sqrt{x} ) ^{2} = 16(\frac{1}{16}x)=x$

g(f(x)) = g $(16x^{2}) = \frac{1}{4}\sqrt{16x^{2} } = \frac{1}{4}(4x) = x$

Answer:

(6,0)

Step-by-step explanation:

If the y-coordinate is 0, it is lying on the x-axis

Same with the x-coordinate. If it is 0, it is lying on the y-axis
