Answer:
At the time measurement starts i.e. initially there was no rainfall i.e. y value is zero.
Step-by-step explanation:
y, in terms of time the rain fell, x.
Now, x is measured in hours after 12 : 00 P.M., with x = 0 corresponding to the time 12 : 00 P.M.
Therefore, the ordered pair (x,y) ≡ (0,0) means that at the time measurement starts i.e. at 12 : 00 P. M. there was no rainfall i.e. y value is zero. (Answer)
You're going to want to combine like terms first off, so 2x+3x=5x. Then you have 5x+7=-41. Now you subtract 7 from both sides, and basically undo that function so you have 5x=-48. Then you do the opposite of multiplying 5, so you divide five from both sides and get -9.6. So x=-9.6. Is that what you wanted? Because if not, ignore this.

Answer:
If 550 toys are made in a day, and 6% of them are defective, about 33 of them will be defective.
Step-by-step explanation:
To calculate the number of toys that will be defective, move the decimal of the percentage 2 place to the left. So the 6% will turn into 0.06, then you would multiply 550 by 0.06. Resulting in about 33 toys being defective.
6% = 0.06
-
550 x 0.06 = 33
