In the xy plane, what is the y intercept of the graph of the equation y=2 (x+3)(x+4)?

Answers

The y-intercept is the value of y when the graph intersects the y-axis.  Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:

y=2(0+3)(0+4)

y=2(3)(4)

y=24

Therefore, 24 is our answer.

Students get a 15% discount off the original prices at the Everything Fluorescent store during its back to school sale. Find the amount of discount on fluorescent notebooks originally priced at $7.99.

Answers

the discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
