Answer:
Not a solution
Step-by-step explanation:
y ≥ 2x + 5
=> Substituting x = 2 and y = -1 in Equation,
=> -1 ≥ 2(2) + 5
=> -1 ≥ 4 + 5
=> -1 ≥ 9 [Not possible]
Therefore, (2,-1) is not a solution of y ≥ 2x + 5
The equation we need to do is 1/11 times 7/22 so the answere would be
7/242
Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.

Answer:
60 child tickets and 72 adult tickets
Step-by-step explanation:
Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60, y =72
