Answer:
1.5
Step-by-step explanation:
The constant of proportionality is the slope
m= (y2-y1)/(x2-x1)
Pick any two points
m = (12-6)/(8-4)
= 6/4
= 3/2
= 1.5
Answer: x2+10x-75= (x-5)(x+15)
Step-by-step explanation:
Ok so we factor by thinking of numbers that can add to 10 and multiple to get -75. so those 2 numbers were -5 and 15. Hope this helps xD
I see that we need to make an expression out of the numbers given above that will end up having a value of 75. It is done as follows:
(6 x (7+5)) + 3 = (6 x 12) +3 = 72 + 3 = 75
Hope this answers the question. Have a nice day.
Answer:

Step-by-step explanation:
Answer:
Explanation:
The proportions of dimes and nickels in the withdrawls recorded by the student are:
- dimes: 12/25
- nickels: 13/25
Thus, the best prediction of the total number of dimes in the bag is found using the same ratio of dimes:
- dimes in the bag = (12/25) × 200 = 96 ← answer
