Answer:

975 bulbs

Step-by-step explanation:

1/40 bulbs were defective

That means 1-1/40 were not defective

40/40 - 1/40 = 39/40 were not defective

We have 1000 bulbs

Multiply the number of bulbs  by the fraction that is not defective to get the number of bulbs that should not be defective.

1000 * 39/40 = 975 bulbs

Is the graph shown at right the graph of -2x + 5y = 20? yes or no? explain your thinking
zimovet [89]
Yes

Rewrite the equation in slope intercept form.
First add 2x to both sides:
5y = 2x + 20
Divide both sides by 5
y = (2/5)x + 4

Based on this equation, the y-intercept is 4, which is true for the graph. The slope is 2/5, which is also true for the graph, seeing as how there are points at (-5,2), (0,4), and (5,6). Between each point you go 2 up and 5 to the right.

Do you think a sequence of translations across the x- or
Serggg [28]

I think just two reflections would do it.

First we reflect around y = -x, the 45 degree line through the origin and the second and fourth quadrant.

Then we reflect through the y axis, x=0.

The composition of the two reflections is equivalent to a 90 degree clockwise rotation.
