I hope I’m not too late. Substitute x = 4y + 5y = 2
y = 2. Substitute this value into the first equation: x + -4 x 2 = -8. So the answer is (-8,2).
Answer:

Step-by-step explanation:
The given equality is

Take the term
to the left hand side. This means the term
will be divided by 

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

Now
and 

So, the missing factor 
The price per cubic inch for the extra large tub will probably be 2000
Answer:
324 cubic inches
Step-by-step explanation:
The dimensions are now 18 x 18 x 1, since you are cutting an inch off each side.
