Answer:
1/4x + 3
Step-by-step explanation:
The question said one-third(1/3) not one-fourth(1/4).
1/3x + 4 can also be written as x/3 + 4.
The similarity statement would be that all three of them have the same sides
Answer:
9a-7
Step-by-step explanation:
8a-6+a-1
Collect like terms
8a+a-6-1
= 9a-7
Answer:
We see two intersecting lines.
It means there is one solution, it is the intersection point.
Solution is (3, 4)
It was easy to find the solution as both lines and their intersection is visible on the graph.
With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.
If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.
With same slopes and different y-intercepts there is no solution.
With same slopes and y-intercepts there is infinitely many solutions.
In 1st fig
A=5×x(let)
9=5×x
in 2nd fig
A=10×2x(5 is doubled so ×also doubled)
A=10×2×9÷5
A=36
