Answer:
(x, y) =(2,-3)
Step-by-step explanation:
4x+3y=-1
3x-9y=33 /:3
4x+3y=-1.....(1)
x-3y=11... (2)
(1)+(2): 5x=10
x-3y=11
x=10/5
x-3y=11
x=2
2-3y=11
x=2
-3y=11-2
x=2
-3y=9
x=2
y=9/(-3)
x=2
y=-3
(x,y)=(2,-3)
Answer:
Yes.
Step-by-step explanation:
It can be expressed as a ratio and it is a fraction.
The rate at which the ice changes is -3/8 lb per hr
<h3>What is the rate the ice changes?</h3>
The given parameters are:
Changes =1 3/4 lb to 1/4 lb
Time = 1/4 hr.
The rate the ice changes is calculated as:
Rate = Change/Time
So, we have
Rate = (1/4 lb - 1 3/4 lb)/(1/4 hr)
Evaluate the difference
Rate = (-1 1/2 lb)/(1/4 hr)
Evaluate the quotient
Rate = -3/8 lb per hr
Hence, the rate at which the ice changes is -3/8 lb per hr
