Answer:
I think the rate of change or slope would be 6 or 6/1
And the equation y=6x
Step-by-step explanation:
You have to make the denominTors even, in this. Case it is 30. So you mutiply the 4 by 3 because you mutiply true 10 by 3 to get 30. So that fraction is now 12/30. Then mutiply the 2 by 2 because the 15 gets multiplied by 2 to get 30. So your equation is now 12/30 - 4/30. And you solve that to make 8/30. Simplify it to get 4/15. 4/15 is the answer. Hope this helps.
Answer:
y = 4 ; x = 4√2
Step-by-step explanation:
This is a 45° 45° 90° triangle meaning the legs will equal each other and the hypotenuse will be equal to the length of the legs times √2.
Since this is a line it has a constant velocity or slope, and the line can be expressed as y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0)
m=(y2-y1)/(x2-x1)
m=(6--4)/(10-4)
m=10/6
m=5/3, using any point we can then find the y-intercept, I'll use (4,-4)
-4=5(4)/3+b
-4=(20+3b)/3
-12=20+3b
-32=3b
-32/3=b so our line is:
y=(5x-32)/3
So there are infinite points on the line segment defined by the equation above on the interval of x=[4,10]
A point? How about the midpoint...x=(4+10)/2=7
y(7)=(5*7-32)/3=1
(7,1)
