Answer:
Step-by-step explanation:
System A
the two lines have the same slope, so they are parallel and never intercept themselves.
the system has no solution.
System B
By multiplying the first equation by -1
x + 4y = -3
The two equations are equals so the lines are the same.
The system has infinitely many solutions
Answer:
L= 10 in
W= 7 in
Step-by-step explanation:
Given data
let the widht be x
W= x
L= x+3
P=34 in
We know that
P=2L+2W
34= 2(x+3)+ 2(x)
34= 2x+6+2x
collect like terms
34= 4x+6
34-6= 4x
28= 4x
divide both sides by 4
x= 28/4
x=7
Put x= 7 in
L= x+3
L= 7+3= 10
Hence the width is 7in the length is 10 in
x would be equal to or less than 4. It would not be possible for it to have a length of 15 because 15x10=150 and the maximum area is 140 sq cm.
