17) 10•6 = 4w

Multiply:

60 = 4w

Divide:

60/4 = 4w/4

15 = w ———————————



18) 180° - S = 65°

Isolate the variable (subtract 180° on both sides):

-S = -115

You can’t have a negative angle so you divide -1 on both sides:

S = 115 ———————————

Answer:

17. w = 15   18. S = 115°

Step-by-step explanation:

17. 10 · 6 = 4w

<em>combine like terms:</em>

=> 60 = 4w

<em>divided by 4 on both sides:</em>

=> w = 15

18. 180° - S = 65°

<em>subtract 180° on both sides:</em>

=> -S = -115° => S = 115°

Which of the following equations have complex roots?
mestny [16]

Answer:

A

Step-by-step explanation:

Complex roots of quadratic functions occur when the <u>discriminant is negative</u>.

<u>Discriminant</u>

b^2-4ac\quad\textsf{when}\:\:ax^2+bx+c=0

Evaluate the discriminant of each of the given equations.

\textsf{A.} \quad 3x^2+2=0

\implies a=3, \quad b=0, \quad c=2

\implies b^2-4ac=0^2-4(3)(2)=-24

As -24 < 0 the equation will have complex roots.

\textsf{B.} \quad 2x^2+1=7x

\implies 2x^2-7x+1=0

\implies a=2, \quad b=-7, \quad c=1

\implies b^2-4ac= (-7)^2-4(2)(1)=41

As 41 > 0 the equation does not have complex roots.

\textsf{C.} \quad 3x^2-1=6x

\implies 3x^2-6x-1=0

\implies a=3, \quad b=-6, \quad c=-1

\implies b^2-4ac=(-6)^2-4(3)(-1)=48

As 48 > 0 the equation does not have complex roots.

\textsf{D.} \quad 2x^2-1=5x

\implies 2x^2-5x-1=0

\implies a=2, \quad b=-5, \quad c=-1

\implies b^2-4ac=(-5)^2-4(2)(-1)=33

As 33 > 0 the equation does not have complex roots.
