The intersection of 
is 
Explanation:
The expression is
To determine the intersection of these two inequalities, let us solve the two inequalities separately.
Consider 
Subtracting both sides by 1, we have,
Also, consider 
Adding both sides by 4, we have,
Using these two simplified inequalities in the expression, we have,
Writing this in the interval notation, we get,
Hence, the intersection of the two interval is
Thus, the intersection of is
Answer:
r = 10q/(p + 30)
so put p+30 in the blank
Step-by-step explanation:
p=10(q - 3r)/r
p = (10q - 30r)/r
pr = 10q - 30r
pr + 30r = 10q
r(p + 30) = 10q
r = 10q/(p + 30)
The rule is add 1.05 because it's 1.8 first then it's 2.85 so you add 1.05 to 1.8 and you will get 2.85. Same with the other numbers.
Answer: c
Step-by-step explanation: The answer is c because t affects the amount of money sold each day so if there were less tickets sold less money would be made and if more tickets were sold more money would be made.
Reflect over x-axis rule: (x,y) -> (x,-y)
(-5,3) --> (-5,-3)
(-2,-6) --> (-2,6)
(-4,-8) --> (-4,8)
