Graph the equations to solve the system. y=2x-5 1/2y=x-5/2
1 answer:
Answer:
all real numbers
Step-by-step explanation:
solution: all real numbers
these are the same equation
we can figure this our by multiplying the second equation by 2
so then it would come out to be
y=2x-5 as well
i attached the graph,
-5 is the y intercept and 2 is the slope since it is in slope intercept form
y=mx+b

Answer:
22. Perimeter = 52 units
Area = 160 Square Units
23. Notation form :
Standard Form : 200000
Step-by-step explanation:
22.
The formula for perimeter is
P = 2 (length + Width )
= 2 ( 2x+3x+1)
= 2(5x+1)
The Formula for Area of a rectangle is
A= length x width
A=
A=
Now we have to find the Perimeter and Area for x = 5
P = 2(5 x 5 +1)
P= 2(26)
P=52 units
A= 6 x 5 x 5 + 2 x 5
A= 150 + 10
A= 160 square units
