Proportional equations are the equations that have the graph which pass through (0,0).

y = -9x is proportional.

y=x is proportional

y=1/2x is proportional

That's it. Only these three equations have (0,0) intercept.

Clare is paid $90 for 18,000 seconds of work. At this rate, how many seconds does it take for her to earn 25 cents? It would tak

Anastaziya [24]

Answer: 50 seconds

Step-by-step explanation:

From the question, we are informed that Clare is paid $90 for 18,000 seconds of work. This means that for Clare to get $1, she'll work for (18000/90) = 200 seconds. From the calculation $1 = 200 seconds

We should note that 100 cents = $1, therefore 25 cents = 25/100 = $0.25.

The seconds that it will take for her to earn 25 cents will be:

= 200 × 0.25

= 50 seconds

Therefore, it'll take 50 seconds for her to earn 25 cent.

<h3>Answer for the first box = 1</h3><h3>Answer for the second box = 2</h3><h3>Answer for the third box = 0</h3>

This gives $f(x) = 1\sqrt{x-2}+0$ which is the same as $f(x) = \sqrt{x-2}$

==========================================================

Explanation:

The general template for a square root function is

$y = a\sqrt{x-h}+k$

where,

'a' handles the vertical stretching/compressing of the graph
h determines the horizontal shifting
k determines the vertical shifting

The graph has not been scaled vertically. In other words, it has not been vertically stretched or vertically compressed. So the value of 'a' is equal to 1.

The value of h is 2 since the graph has been shifted 2 units to the right. If we wanted to go left, then h would be negative.

The value of k is 0 because there is no vertical shifting going on.

In summary,

a = 1, h = 2, k = 0

Leading

$y = a\sqrt{x-h}+k$

to turn into

$y = 1\sqrt{x-2}+0$
