These are all linear equations, because all of the variables are raised to the positive FIRST power: <span>-4v+2w=7, x/4=y, x=-5
The last equation, </span><span>2/x +3/y=6, is not linear, because the powers of the variables are negative:
2x^(-1) + 3y^(-1) = 6 NON LINEAR</span>
Answer:
Step-by-step explanation:
k = (4ac – b2) / 4a. Find the vertex of y = 3x2 + x – 2 and graph the parabola.
Answer: 1. 30 2. 10
Work:
5•2T T=3
2^3= 2•2•2=6
5•6=30
5•2T T=1
2^1= 2= 2
5•2=10
