Answer:
w=3/5 or w=-5
Step-by-step explanation:
5w^2+22w=15
5w^2+22w-15=0 (quadratic equation)
a=5, b=22, c=-15
w1,2 =(-b+-sqrt(b^2-4ac))/2a
w1,2 =(-22+-sqrt(22^2-4*5*(-15))/2*5
w1,2 =(-22+-sqrt(484+300))/10
w1,2=(-22+-sqrt(784))/10
w1,2=(-22+-28)/10
w1=(-22+28)/10, w2=(-22-28)/10
w1=6/10, w2=-50/10
w1=3/5, w2=-5
Hey there!
The rate of change for these two points would be m = 1/2. Subtract the two y points from each other and then the two x points from each other. Then you divide them. Or get a simplified fraction.
Hope this helped!
Well if you subtract 7/8 from 2/5 you get 19/40 which is 47 muffins Maria can make
The average cost of a two-bedroom apartment in the city will be about $1135
Step-by-step explanation:
The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.
Given that the average cost of one-bedroom apartment is $724, then using this value for x
yˆ=1.377*724+137.763 = 1134.711
This value is approximately $ 1135
