To have infinite solutions, they have to be th esame line
match waht we do know
bx-6y=18
the coefient of y is -6
other one is
2x-3y=9
-3 times 2=-6
times 2nd equation by 2
4x-6y=18
bx-6y=18
b=4
Answer: 118.40, 300, $18,000
<u>Step-by-step explanation:</u>
a) p(x) =
p(8) =
= -1.60 + 120
= 118.40
b) R(x) = x * p(x)
=
=
a=, b=120
x =
=
=
= 300
c) R(x) =
R(300) =
= -18,000 + 36,000
= 18,000

Answer:
15.2
Step-by-step explanation:
As it is given that PS is perpendicular bisector of QR and PQ = PR = 12.4
and SR = 7.6
So,
QR = QS + SR
= 2(SR)
= 2×7.6
= 15.2
Answer:
2+1 equal to 4 than 3+1 equal to 4 then 21+6 equals to 27
