Step-by-step explanation:
The money was shared in the ratio of their ages which represents
7:8:10 respectively
- Lien = 8
- 7+8+10=25
- 8/25 x 100/1
- 0.32 x 100
- = $32
The first thing we must know in this case is that the distance is equal to the speed for time.
We have then:
For Chris:
d1 = 40 * t
For Amy:
d2 = 60 * (t-2)
The distance between both will be given by the hypotenuse of the rectangle triangle:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
Answer:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
option 3
Answer:
A)The slope of the graph is 1
B) The table is 3
C) The equation is 1/2
D) The table
Step-by-step explanation:
y2-y1/x2-x1=the slope
Pick two undefined points {such as 5,0 and 0,-5)
5-0/0+5=1
The slope is 1.
~~~~~~~~~~
Same equation of slope, you just have to find two points (I chose 2,2 and 4,3
The slope of the equation y=0.5x+1 is 1/2 or 0.5
~~~~~~~~~~
You choose two points (I chose 2,9 and 1,6)
Slope equation
9-6/2-1=3/1=3
Slope is 3
~~~~~~~~~~~
The greatest change is in the table. You know this because it has the greatest slope and if you draw it out on a graph, it has the most significant change.
Good luck!
Answer:
Proportional
Step-by-step explanation:
Proportional functions can be written as 
, where 
is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of 
and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.
