Answer:
(a) 305 visitors (b): Saturday to Sunday
B = {a, b, c, d}
C = {0, a, 2, b}
B ∪ C = {a, b, c, d, 0, 2}
<h3>Answer: E)</h3>
Everything from the set B and everything from the set C give to one set. Duplicated elements are written only once.
Answer:
Step-by-step explanation:
Simplifying
4x + 2y = 18
Solving
4x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
4x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
4x + 0 = 18 + -2y
4x = 18 + -2y
Divide each side by '4'.
x = 4.5 + -0.5y
Simplifying
x = 4.5 + -0.5y
////////////
Simplifying
y = -2 + 9
Combine like terms: -2 + 9 = 7
y = 7
Solving
y = 7
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 7
Parameterize
