Y = 2x - 4 Y = x - 2 = ?
1 answer:
Answer:
the graph is below for the answer
Step-by-step explanation:
y = 2x - 4 = x=2
y = x - 2 = y=0
--------------------------------------------
step by step
Step 1: Substitute 2x−4 for y in y=x−2:
y=x−2
2x−4=x−2
2x−4+−x=x−2+−x (Add -x to both sides)
x−4=−2
x−4+4=−2+4 (Add 4 to both sides)
x=2
Step 2: Substitute 2 for x in y=2x−4:
y=2x−4
y=(2)(2)−4
y=0 (Simplify both sides of the equation)
x=2 and y=0

Answer:
So, the required width of rectangular piece of aluminium is 8 inches
Step-by-step explanation:
We are given:
Perimeter of rectangular piece of aluminium = 62 inches
Let width of rectangular piece of aluminium = w
and length of rectangular piece of aluminium = w+15
We need to find width i.e value of x
The formula for finding perimeter of rectangle is:
Now, Putting values in formula for finding Width w:
After solving we get the width of rectangular piece :w = 8
So, the required width of rectangular piece of aluminium is 8 inches
