Answer:
3m + 4
Step-by-step explanation:
4 is the starting number of stamps and 3m represents 3 stamps per month
Answer:
Neither
Step-by-step explanation:
step 1
Verify if the lines are parallel
we know that
If two lines are parallel, then their slopes are the same
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Compare
2/7≠7/2
therefore
The lines are not parallel lines
step 2
Verify if the lines are perpendicular
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Multiply
2/7*7/2=1
1≠-1
therefore
The lines are not perpendicular
Answer:
x + y ≥ 3
x + y ≤ 3
Step-by-step explanation:
In the picture attached, the problem is shown.
The solution to the system:
x + y ≥ 3
x + y ≤ 3
is the line x + y = 3
In order to get a solution to a system of inequalities that is a line, we need the same equation on the left (here, x + y), the same constant on the right (here, 3), and the ≥ sign in one inequality and the sign ≤ in the other one.
Answer:
((2 x^2 + 1)^2)/(x^2)
Step-by-step explanation:
Simplify the following:
(2 x + 1/x)^2
Hint: | Put the fractions in 2 x + 1/x over a common denominator.
Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:
((2 x^2)/x + 1/x)^2
Hint: | Combine (2 x^2)/x + 1/x into a single fraction.
(2 x^2)/x + 1/x = (2 x^2 + 1)/x:
((2 x^2 + 1)/x)^2
Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.
Multiply each exponent in (2 x^2 + 1)/x by 2:
Answer: ((2 x^2 + 1)^2)/(x^2)
