U have the to use the formula
y2-y1/x2-x1
that will get u the slope
-10-8 = -18
-9-1= -10
this give u 18/10 which can be simplified to 9/5
so the slope is 9/5
hope this helps!
D. multiplying by .6 is what you always have left.
3/3 would be 1 hour
3/18 of the lawn would be done in 1 hour
18/3=6
6*1 = 6
it would take 6 hours to do the whole lawn
Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
Average rate of change is just the slope betwen the points
that is just the slope between (-3,-3) and (-4,-1)
slpe between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so slope between (-3,-3) and (-4,-1) is (-1-(-3))/(-4-(-3))=(-1+3)/(-4+3)=2/-1=-2
the average rate of change is -2
