Find all complex solutions of 5x^2-6x+2=0.
gregori [183]
We use quadratic formula for that one
remember that √-1=i

so

for
ax^2+bx+c=0
x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so
given
5x^2-6x+2=0
a=5
b=-6
c=2

x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}
x=\frac{6+/-\sqrt{36-40}}{10}
x=\frac{6+/-\sqrt{-4}}{10}
x=\frac{6+/-2i}{10}

x=\frac{3}{5}+\frac{i}{5}, \frac{3}{5}-\frac{i}{5}

tangare [24]

Answer:

The answer would be 5.

Step-by-step explanation:

If you take away 18 from 90 would be 72.

72 - 18 =54

54 - 18 =36

36 - 18 =18

18 - 18 =0

If you count that would equal 5 .

Hope this helps .

What is a sequence of transformations?
MrMuchimi

Answer:

B, Two or more translations, reflections, or rotations that map a pre-image to its image

Step-by-step explanation:

A sequence is an order of events. So we want to look for an answer that includes an order of events. This already knocks out C and D.

Now we are left with A and B. It is not A because the sequence does not require all three rigid transformations.

It is B because we need at least two transformations to have an order of events and these order of events need to map the image to its pre-image. But also because the other ones were wrong. Hope this helps!

University theater sold 529 tickets for a play. Tickets cost $25 per adult and $15 per senior citizen. If total receipts were $9
astra-53 [7]

Adults = x

Senior Citizens = y

x + y = 529......1

25x + 15y = 9745...2

Multiply (1) by 15

15x + 15y = 7935....3

25x + 15y = 9745....2

Subtract 3 from 2

10x = 1810

 

x = 181

Substitute x = 181 in

Eq (1)

x + y = 529

181 + y = 529

y = 529 - 181

y = 348

181 adults and 348 Senior Citizens

Hope this helps.
