Answer:
B. Stratified random sample is the correct answer
Answer:
Im not sure exactly what you want the function to be. Because it can be any number. only the signs would change it
Step-by-step explanation:
okay so lets try this then..
if f(x) is an even number...let say 2
then f(-2)= 2x²+x+6
then it would be 2(-2²)+(-2)+6......-4

Hello!
4x - 9y = 20
2x - 6y = 16
You first need one of the variables have the same coefficient
We can do this by multiplying the second equation by 2
4x - 12y = 32
Subtract the equations to get rid of x
4x - 9y = 20
4x - 12y = 32
3y = -12
Divide both sides by 3
y = -4
Put y into one of the original equations
2x - 6(-4) = 16
Multiply
2x - -24 = 16
We you subtract a negative it is the same as addding
2x + 24 = 16
Subtract 24 from both sides
2x = -8
Divide both sides by 2
x = -4
The answers are x = -4 and y = -4
Hope this helps!
My reasonable estimate might be about 2 1/2 feet. I know that because taking three rulers up to your bedroom or a normal room and get about 2 or 2 1/2 feet
Answer:
I think the constant is 2.
Step-by-step explanation:
5 is coefficient because it is with a variable. So 5 cannot be constant.
