2/10 = 4/x
Cross multiply
2x X= 10x4
2x = 40
Eliminate
2x/2 = 40/2
x = 20
Answer:
I think B
Step-by-step explanation:
because their age group is 20-25 more of a constant age group
compared to 20-30
Step-by-step explanation:
In the picture above.
Number 2 I suppose that as a straight line
so , it becomes easy to solve for y angle.
I hope that it's a clear solution.
Answer:
your slope is -10, and the y-intercept is 200
Step-by-step explanation:
Start at (0,200), or just 200 on the y axis. your slope is -10, or -10/200 in rise over run form. you want to go to the right one, and down 10. So make a dot at (0,200), then (1,190), then (2,180) and so on. to go in the negatives it is the opposite. left one, then up 10, so (-1, 210), then (-2,220) and so on.
