Answer: Plot a point at (-6,5) then just go start up. That is your graph
Step-by-step explanation:
Range is left to right so that means that the only point on the x axsis you can plot is -6 and the domain is up and down so you cant plot a point below 5
With what? what’s the question
Answer:
Step-by-step explanation:
c.
y= 30x² +44x +16
factor
y= 2 (15x² +22x +8)
find zeros
15x²+22x+8=0
ax²+bx+c=0
x= (-b±√(b²-4ac))/2a
x= -22±√484-480/30 = -22±2/30 = -11±1/15
there are 2 zeros x= -10/15 ; x= -12/15
d.
y= 10x² +60x +80
factor
y= 10(x²+6x+8) = 10( x+2)(x+4)
finding zeros
x+2 =0 so x= -2
x+4 =0 so x= -4
there are 2 zeros x= -2; x= -4
A mean is just another word for average. We get the average by adding up all the data number and dividing this sum by the number of data numbers there are.
So that list all added up is 40, and since there are 10 numbers, we divide 40 by 10, which gives us a mean of 4 people per household.
