Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution
So A, C, D
5X+yb=zmh
5x+yb-yb=zmh-yb
5x=zmh-yb
5x/5=zmh/5-yb/5
x=mhz-by/5
Y - 9 = 3(x + 1) and y = -1/3x + 5 are perpendicular....because the slopes are negative reciprocals of each other
Answer:
All except one interval [-2,8]
Step-by-step explanation:
Notice that the function, wich an hyperbola, has a vertical asymptote in both -2 and 8 and there is nothing between this two values.
So we will exclude what's between them out of the domain.
Answer:
5. -2 3/4, -2.2, 2.8, 3 1/8
6. -0.6 , 0.65 , 2/3 , 4/5
