Tell whether the given ordered pair is a solution of the equation y = -2 + 5;(2,1)
1 answer:
<em>Note: your equation is a little bit unclear. Thus, I am assuming that </em>
<em>y = 2x+5</em>
<em> Anyway, the procedure remains the same. It would anyways clear your concept.</em>
Answer:
We conclude that the ordered pair (2, 1) is a solution.
Step-by-step explanation:
Given the equation
Check for point (2, 1)
substituting the point (2, 1) in the equation to check whether the ordered point satisfies the equation or not.
plug in x = 2 and y = 1
1 = -2(2)+5
1 = -4+5
1 = 1
R.H.S = L.H.S
TRUE
Therefore, the given ordered pairs satisifes the equation.
Hence, we conclude that the ordered pair (2, 1) is a solution.

Answer:
The correct answer is 4 window frames.
Step-by-step explanation:
Sue bought 54 feet of lumber for building window frame.
Each window frame requires 13 1/2 feet = feet of lumber.
Therefore the number of window frames Sue can make with 54 feet of lumbers she bought is given by dividing the total amount of lumber she has by the lumber it takes to make a single window frame.
= × 2 = 2 × 2 = 4
Thus Sue can make 4 window pane from 54 feet of lumber, each of 13 and a half feet.
