Answer: A & C
Step-by-step explanation:
g(x) = 8 means where is y = 8?
when we go to -4 on the x-axis, the y value there is 8. so this works!
when we go to 6 on the x-axis, the y value is 6. we were looking for 8. so this does not work.
when we go to 9 on the x-axis, the y value is 8. so this works!
A & C
If B is the midpoint of AC, that means that the distances from A to B and B to C are the same. The distance from A to B is 8x + 4, and the distance from B to C is 10x - 6, so we can set these two equivalent:
8x + 4 = 10x - 6
Solving for x:
4 = 2x - 6 (subtract 8x from both sides)
10 = 2x (add 6 to both sides)
5 = x (divide both sides by 2)
So, x = 5, which is the second option given.
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are
All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then
Here, k=5.
Hence the rate of change is constant that is 5.
I think it's B and D because both of them will give you the same answer which is 2.71 but turn it into fraction.
