Answer:
Yes
Step-by-step explanation:
To determine is an ordered pair is a solution to the system of equations, substitute its coordinates into each of the equations.
An ordered pair is written in the form (x, y), so x=1 and y=2.
y = -2x +4
2 = -2(1) + 4 <=simplify this by multiplying (-2)(1)
2 = -2 + 4 <= add
2 = 2 <= same answers
LS = RS
7x - 2y = 3
7(1) - 2(2) = 3 <=simplify this but multiplying 7(1) and 2(2)
7 - 4 = 3 <= subtract
3 = 3 <= same answers
LS = RS
Since (1, 2) satisfies both of the equations, it is a soltuion to the system of equations.

Answer:
point form:(2,-2),(-3,13)
Step-by-step explanation:
You solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
Step-by-step explanation:
First, we gather the data:
The model is a single 
landing strip with 
This based on the assumption that service times are exponential.
Then, we must find the maximum rate such that 
Using the table, we find that:
if and only if

The hourly pay before the increase for marta and khalid is 21 and 17.5.
Given:
the ratio of martas hourly pay to khalids hourly pay is 6:5 both marta and Khalid get an increase of 1.50 in their hourly pay The ratio of Martas hourly pay to Khalid hourly pay after this increase is 13:11
Let x and y be the hourly pay before increase
x/y = 6/5
x = 6/5*y
x + 1.50 / y + 1.50 = 13/11
11(x+1.50) = 13(y+1.50)
11x + 16.5 = 13y + 19.5
11(6/5*y) = 13y + 19.5 - 16.5
66y/5 = 13y + 3.5
66y - 13*5y / 5 = 3.5
66y - 65y = 17.5
y = 17.5
x = 6/5*17.5
= 105/5
x = 21
