Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
15x-4y=-50
3x-2y=-16
---------------
15x-4y=-50
-5(3x-2y)=-5(-16)
------------------------
15x-4y=-50
-15x+10y=80
-------------------
6y=30
y=30/6
y=5
3x-2(5)=-16
3x-10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2
Answer:
Extra snow needed > 0. 3 inch
Step-by-step explanation:
Given that:
Cancelation occurs when > 2.5 inch of snow accumulates each hour
Accumulation rate = 11/5 inch per hour
Extra snow Accumulation needed to cancel. School ;
Extra snow needed > cancelation volume - current rate
Extra snow needed > (2.5 - 11/5)
Extra snow needed > 0. 3 inch

Answer:
(a) not proportional
(b) k = 7/8
Step-by-step explanation:
When a linear equation is of the form ...
y = mx + b
with b ≠ 0, the relation is NOT PROPORTIONAL.
__
If b=0, so the equation is of the form ...
y = kx
then the relation IS PROPORTIONAL. The constant of proportionality is k.
__
(a) Not proportional
(b) Proportional with k = 7/8
