<h2>1)</h2>

This must be true for some value of x, since we have a quantity squared yielding a positive number, and since the equation is of second degree,there must exist 2 real roots.

Well he started off correct to the point of completing the square.

Answer:
6y + 4x = 18 5/6
Step-by-step explanation:
-2x+5y=19
y= -5/6x - 1/6
Combine the xs
Combine the ys
Combine the whole numbers
6y + 4x = 18 5/6
Answer:
I'm pretty sure that this is correct.
Step-by-step explanation:
this is the equation of a straight line that is generally written
y
=
m
×
x
+
q
m is the slope of the line and is the proportionality coefficient between y and x.
The larger m is, the more the line is hanging
q (-3) is the intercept with the Y axis and is the value you find if you put x=0 (this is the axis y equation)
similarly if you put Y=0 (that is the equation of X axis you find the intercept with X axis that is X= 3/2

If I am wrong I am SO SO <em>Sorry.</em> But I hope that I <em><u>Helped!</u></em> :D
Answer:
No
Step-by-step explanation:
Here we are taking only one measurement: the height of one person. Strictly speaking, this is NOT a statistical question.
"List the heights of a sample of 50 first-graders" would definitely be a stat. question.
