Answer:
x = 10 - 2y
Step-by-step explanation:
The question is telling you to express x in terms of y. Essentially, you solve the given equation(s) for x.
x can be found from the first equation by subtracting 2y from both sides:
x = 10 - 2y
_____
When there are infinitely many solutions, either x or y can be arbitrarily chosen, and the appropriate value computed for the other variable.
Here, the answer is telling you "type an expression using y as the variable as needed." That is, y is selected to be the variable arbitrarily chosen, and we need an expression that will tell us the corresponding value of x. The appropriate expression is found by rearranging the equation(s) to "make x the subject". (I call that process "solve the equation for x.")
Hi!
You can round 1,467 to 1,400 because it is 4 is less than 5, and then multiply that by 4:
1,400 × 4 = 5,600
Now, to find the product, we do not round:
1,467 × 4 = 5,868

Answer:
(6, - 2)
Step-by-step explanation:
To determine which point is a solution to the system, substitute the coordinates of the point into the left side of the inequalities and compare the value to the right side
(6, 1)
6 - 1 = 5 < 7
6 + 2 = 8 > 5
(6,1) does not represent a solution
(8, - 1)
8 + 1 = 9 > 7
8 - 2 = 6 > 5
(8, - 1) does not represent a solution
(6, 2)
6 - 2 = 4 < 7
6 + 2 = 8 > 5
(6, 2) does not represent a solution
(6, - 2)
6 + 2 = 8 > 7
6 - 4 = 2 < 5
(6, 2) represents a solution to the system
