Answer:
The Answer is P = (-2.5 , 1 )
Step-by-step explanation:
Let, the point is P(x,y)
then, 
=>
∴
Again, 
=>
∴
Thus, P = (-2.5 , 1 )
Answer:
512ft³
Step-by-step explanation:

Answer:
Total cost is $177.50.
Step-by-step explanation:
Rackets:
Divide the cost for racket by 6 to find the cost per racket.
186÷6=31
Multiply 31 by 5 to find the cost for 5 rackets.
31×5=155
$155
Tubes of balls:
Divide 27 by 6 to find the cost per a tube of balls.
27÷6=4.50
Multiply 4.50 by 5 to find the cost for 5 tubes of balls.
4.50×5=22.50
$22.50
Add the amounts for rackets and tubes of balls to find the total cost.
155+22.50=177.50
The total cost is $177.50.
Hope this helps!
City A = x
City B = y
1st equation: 4x-8 =3y
2nd equation: x-2y = -3 , rewrite as x = 2y-3
replace x in eq. 1 with equation 2
4(2y-3) -8 =3y
8y-12-8=3y
8y-20 = 3y
-20 = -5y
y = -20/-5 = 4
x = 2y-3 = 2(4)-3 = 5
City A was 5° C, and City B was 4° C.
