15 a store manager receives a delivery
of 2 boxes of lightbulbs. each box
contains 25 lightbulbs. the store
manager tests all the lightbulbs and
finds that 2 of them are defective.
based on these results, what can
the store manager predict about the
next delivery of lightbulbs?
a a delivery of 3 boxes will contain
3 more defective lightbulbs than
a delivery of 2 boxes.
b a delivery of 4 boxes will contain
2 more defective lightbulbs than
a delivery of 2 boxes.
c a delivery of 5 boxes will contain
10 more defective lightbulbs than
a delivery of 2 boxes.
d
a delivery of 6 boxes will contain
3 more defective lightbulbs than
a delivery of 2 boxes.

B

Step-by-step explanation:

For each box, there is 1 defective lightbulb. Therefore, a delivery of 4 boxes will have 4 defective lightbulbs. A delivery of 2 boxes has 2 defective lightbulbs. 4 defective lightbulbs subtracted by 2 defective lightbulbs equals 2 more defective lightbulbs in 4 boxes than 2. Therefore, it is B.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the correct answer is 5 6 and 7
