Hey there!
(9) 2x-9y=45
... -9y=-2x+45
... y = (2/9)x - 5
Slope = 2/9
y-intercept = (0,-5)
(11) 3y+2x=-15
... 3y=-2x-15
... y = (-2/3)x - 5
Slope = -2/3
y-intercept = (0,-5)
(12) 10x+8y=40
... 8y=-10x+40
... y=(-10/8)x+5
Slope = -5/4 (after simplifying )
y-intercept = (0,5)
Hope my answer helps!
Step-by-step explanation:
1) The very first thing to do is read and write down the given data carefully.
From here we can decipher if the intersect asked her is SIMPLE INTEREST or COMPOUND INTEREST.
2) Next step is to put the given values in the appropriate formula correctly and decipher what value is needed to be found.
3) The final step is to do the neat calculations so that there is no error while doing it.
By this we can compute the desired value correctly.
751*5=3.755, which is the number of toys made in a week.
By multiplying 3.755 by 3, you find that the workers make 11.265 toys in three weeks.
Answer:
56!
Step-by-step explanation:
To find the number of bottles that can be packed in 480 seconds, you need to divide the total amount of time, 480 seconds, by 8.6, the amount of time it takes to pack each bottle.
480/8.6=55.8139534884, which rounds up to 56!
