(a) y=x/7
(b) the rate of change is 7
(c) if he ran for 70 minutes then his distance is 10 miles.
*for (c) just plug in the number given. Replace it with x and divide it by 7.*
The lcd of 25 50 and 75 is 150
Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2

Correct!
When thinking of what determines a plane we can make the following comparison.
If a plane was the top part of a table, 3 legs, whose tops are points W, X and Y may hold it, as shown in the first picture.
but if the legs are in a line, as in the second figure, they may not hold the top part, so 3 collinear points cannot determine a plane.
