No, because if you are a true friend you would spend a little extra money to make your three friends happy.
The equation would be y = 7.50x - 8.
The graph would be an increasing straight line.
The opposite sides PQ and RS of the parallelogram PQRS are congruent
The value of the length QS is 6 cm
<h3>How to determine the length QS?</h3>
The given parameters are:
PQ = 4x - 1
RS = 3x + 7
Opposite sides are congruent.
So, we have:
4x - 1 = 3x + 7
Collect like terms
4x - 3x = 1 + 7
Evaluate the expressions
x = 8
The perimeter is calculated using:
Perimeter = 2(QS + RS)
This gives
2(QS + RS) = 74
Divide by 2
QS + RS = 37
Substiute RS = 3x + 7
QS + 3x + 7 = 37
Substitute 8 for x
QS + 3*8 + 7 = 37
This gives
QS + 31 = 37
Subtract 31 from both sides
QS = 6
Hence, the value of the length QS is 6 cm

Answer:
x = 5 and y =-2
Step-by-step explanation:
2x+3y = 4
3x+2y = 11
Multiply first equation by 2 throughout and second equation by 3 we get
4x + 6y = 8
9x + 6y = 33
subtracting the equations we get
9x - 4x = 33-8
5x = 25
x = 5
substituting x= 5 in 1st equation
10 + 3y = 4
3y = 4-10
3y = -6
y = -6/3
y= -2
