(1, 3)
General Formulas and Concepts:
<u>Algebra I</u>
- Coordinates (x, y)
- Reading a Cartesian (Rectangular) plane
- Solving systems of equations by graphing
Step-by-step explanation:
Where the 2 lines intersect will be the solution set to the systems of equations.
If the lines are parallel, they will have no solution.
If the lines are the same, they will have infinite amount of solutions.
The correct answer is line TX and line QX are perpendicular.
Step-by-step explanation:
i)
2(x+2)=7
2x+4=7
2x=7-4
2x=3
x=3/2
ii)3x + y =8 , y=x
3x + x = 8
4x = 8
x = 2
Answer: 225
Step-by-step explanation: If the whole area is 900 square inches you divide by the sides of the square 4 and divide by the total area 900. 900/4 = 225
12, because 150/25=6x2 is 12
