Graphs exercise 1: (a) a simple graph of 4 vertices has eigenvalues 3,-1,-1,-1}. how many edges must it have? draw the graph (b) a simple graph has a spectrum of 4 numbers, three of which are given below (the values are rounded). find that graph (i) {-1.5, -, 0.3 (ii) { 3/5

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

he earned 78.75 in interest.

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
