Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
2x +8=2x+8
2x-2x=8-8
0x=0
So the answer is 0
Answer:
1/8, 1/4, 1/2, 1/2, 1/8 plus 1 tablespoon, 3/8, 1/16, 1/2, 1/8, 1/4
Step-by-step explanation:
multiply the denominator by 2 for each one because fractions are smaller as the number gets bigger.
Answer:
400
Step-by-step explanation:
The assumption behind mark-recapture methods is that the proportion of marked individuals recaptured in the second sample represents the proportion of marked individuals in the population as a whole. In algebraic terms, This method is called the Lincoln-Peterson Index of population size.
Answer:
A =78.5 in^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
A = pi * r^2
A = 25 pi
Using 3.14 for pi
A = 25 (3.14)
A =78.5 in^2
