Describe the translation. y = (x-5)squared +5 - y = (x-))squared +0

vovangra [49]

In functions; translations are used to move lines, points or shapes across the graph (i.e. up, down, right or left).

The translation from $y = (x - 5)^2 +5$ to $y = (x - 0)^2 +0$ is to shift $y = (x - 5)^2 +5$ to the left by 5 units and then downward by 5 units

The given parameters are:

$y = (x - 5)^2 +5$

$y = (x - 0)^2 +0$

Assume the first point is: $y = (x - 5)^2 +5$

While the second is: $y = (x - 0)^2 +0$

The first point is first shifted left by 5 units

The rule to this translation is: $(x,y) \to (x + 5,y)$

So, we have:

$y' = (x - 5 + 5)^2 + 5$

$y' = (x - 0)^2 + 5$

Next, the resulting function is shifted down by 5 units.

The rule to this translation is: $(x,y) \to (x,y- 5)$

So, we have:

$y" = y' - 5$

This gives:

$y" = (x - 0)^2 + 5 - 5$

$y" = (x - 0)^2 + 0$

Hence, the translation from $y = (x - 5)^2 +5$ to $y = (x - 0)^2 +0$ is to shift $y = (x - 5)^2 +5$ to the left by 5 units and then downward by 5 units

Andrew makes $6 an hour plus $9 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week

Novosadov [1.4K]

Part A ) The equation is W = $ 6x where x ≤ 40, W is the amount of wage earned and x hours in a week when there is no overtime.

Part B) The equation is W = $ 6*40 + $9 y =$ 240 + $9 y where y as the overtime hours = total number of hrs - 40.

Part C) $ 240 + $9 y = $330. y is 10 hrs. Hence the total hours is 50 hrs.

PLEASE HELP!!!

Alenkinab [10]

Answer:

y=-3/2x+3

Step-by-step explanation:

The equation for slope intercept form is y=mx+b. The variable m stands for slope, and b stands for the y-intercept.

First, since there's an easy y-intercept to find, we can start from there! The line goes right across the y-axis at 3. 3 is the y-intercept. The equation looks like this now:

y=(?)x+3

Next, find the slope. The easiest way to do this is to look at the points the line goes straight through. These would be (0,3) and (2,0). Slope is written rise over run. If you look at the graph, from the point (2,0), you can find the next point, (0,3), by rising 3 and going over (running) -2, which is actually going backwards. So, as a fraction, the slope is - $\frac{3}{2}$ .

Another way to find slope is to find two points on the line. We can use the same points we used above again. To find slope with the two points, subtract the y's and then subtract the x's in the same order. Subtract the y's over the x's.

0-3=-3 As you can see, we still got the slope as - $\frac{3}{2}$ .

2-0 2

When we plug in all of the numbers, the equation looks like this: y=-3/2x+3

I hope this helps you out!! Have a great day (*^▽^*)
