Answer: The third graph.
The difference between temperatures for every increase (1km) in altitude is consistent (6.5), meaning that it is a straight line.
Then, you would have to match the x and y values on the charts to the coordinates on the graph. Ex: (8.5, 1), (2, 2), (-4.5, 3) etc.
πr² = π.5.5 = π25 units² or 78.5 units²

Your answer will be y=-3x+2
Answer: Option 'a' is correct.
Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :
then,
discriminant value will be
There are 3 properties regarding discriminant value as follows:
So, here we need a zero real number solutions i.e. there does not exists any real number.
So,
Hence, Option'a' is correct.
To solve the system if equations substitute the given values and simplify:
4x+2y=7
y=5x
To start off we are given what h equals already so we do not have to solve for it. This means we can just plug in its values into the first equation.
4x+2(5x)=7
Solve for x
4x+10x=7
14x=7
x=7/14
x=1/2
Now that we have an x value substitute back into the second equation to find the y value and be able to create a coordinate point.
y=5x
y=5(1/2)
y=5/2
y=2.5
So your answer would be
(1/2,5/2) or (0.5,2.5)
I hope this helps!
