Answer:
(-4,-5)
y= -5
x= -4
Step-by-step explanation:
y=3/2x+1
y=3/4x-2
solve using the comparison method
3/2x+1=3/4x-2
subtract 3/2 from both sides
-3/4x+1=-2
subtract 1 from both sides
3/4x=-3
divide both sides by 3/4
x= -4
substitute the value of x into an equation
y=3/2(-4)+1
distribute
y= -6+1
add, but 6 is negative so subtract
y= -5

Answer:
3x^2 -x-6
Step-by-step explanation:
If f(x) = 3x^2 - 4 and g(x) = x +2
(f-g)(x)
I like to line them up vertically
3x^2 - 4
-( x +2)
----------------------
Distribute the minus sign
3x^2 - 4
- x -2
----------------------
3x^2 -x-6
