Answer:
x= 0 x=4
Step-by-step explanation:
2x^2=8x
Subtract 8x from each side
2x^2 -8x=8x-8x
2x^2 - 8x =0
Factor 2x
2x( x-4) =0
Using the zero product property
2x =0 x-4 =0
x= 0 x=4
Answer:
The answer is 6/13
Step-by-step explanation:
First you add them all together, then choose the number of purple marbles ,make a fraction ,and simplify if necessary.
hope this helps
42. The mean is the total of the numbers divided by the amount of numbers. In this case the amount of numbers is 7 and the mean is 6. That means that the total of the numbers divided by 7 equals 6. To find the total you just do the opposite, multiply 7 by 6 and you get 42.
Answer:
You will likely need to actually measure a few people for parts 1 and 2, but the statement in part 2 should be something like "The length of the forearm of one person will be very similar to the length of their foot" or "As the length of the forearm increases, the length of the foot will increase in similar amounts".
Since the equation in pt.3 is y = 0.860x + 3.302, if x=17, then 0.860(17) + 3.302=17.922
The next question is dependant on pt.1
The data from pt.1 should be somewhat similar to the data you collected, the values between them are different because of the allowed error margin between the two.
The data can be made into a function using the "line of best fit". The equation in part A represents a function because there are no two points where two y coordinates are on the exact same x coordinate.
