You are supposed to answer where the function, h(x), is decreasing. In other words, where is “y” decreasing.

In this graph, I believe it would be from (-3,4)U(8,infinity). I hope this helps.

Lucy earns money babysitting. Her earnings and hours worked represent a direct variation. She worked for 4 hours and earned $25.

SashulF [63]

For this case we have that by definition, a direct variation is given in the form:

$y = kx$

Where:

k: It is the constant of proportionality

According to the statement we have to:

$y = 25\\x = 4$

Substituting:

$25 = k4\\k = \frac {25} {4}$ $k = 6.25\ for\ \frac {dollars} {hour}$

On the other hand we have:

$y = 4\\x = 25\\4 = k25\\k = \frac {4} {25}$

$k = 0.16\ for\ \frac {hours} {dollar}$

Answer:

$k = 6.25 for \frac {dollars} {hour}\\k = 0.16 for \frac {hours} {dollar}$

In a store, 7/200 of the shirts are yellow and 69/600 are pink . What percent of the shirts are not yellow or pink.?

Shkiper50 [21]

Answer:

510/600 of the shirts are not yellow or pink.

Step-by-step explanation:

First we turn 7/200 with a denominator of 600.

7/200 = 21/600

Next we add 69/600 with 21/600.

69/600 + 21/600 = 90/600

Now we subtract 600 by 90.

600 - 90 = 510.

So, the answer is 510/600

Hope this helps! :)
