Im not entirely sure but, if you're on plato answer D is correct
model 1 has a random pattern and is fit for the data
the answer is 10x
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
x
=
10
Estimation: 500×7=3,500
Product: 503×7=3,521
Answer:
(-3, 1)
Step-by-step explanation:
x-y=-4
3x-y=-10
------------
y=x-(-4)=x+4
3x-(x+4)=-10
3x-x-4=-10
2x-4=-10
2x=-10+4
2x=-6
x=-6/2
x=-3
-3-y=-4
y=-3-(-4)=-3+4=1
x=-3, y=1. (-3, 1).
