Step-by-step explanation:
convenience Sampling : this is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand.
Answer:
Step-by-step explanation: The simplification calculator allows you to take a simple or complex expression and simplify and reduce the expression to it's simplest form.
F(x)=9x
f(X)=9(-2)
f(x)= -18
Answer:
(4,-4)
x=4
y= -4
Step-by-step explanation:
We know that y is equal to and so we can plug the y value in for x into the other equation
-2x+5(-x)= -28
Solve for x
-2x-5x= -28
-7x= -28
x=4
Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y
y= -(4)
y= -4
