Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a

a = 10

b = -1

c = 9

1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)

1 +/- sqrt(1 - 360) / 20

x = 1 +/- sqrt(359i) / 20

Hope this helps!

If f(x) = 2x−5, then what is the value of f(2) + f(5)

DochEvi [55]

First of all f(2)=2(2)-5=-1 and f(5)=2(5)-5=5
so
f(2)+f(3)=-1+5=4

What is the missing number in the synthetic division problem below?

Crank

Given:

A synthetic division problem.

To find:

The missing number it in the given synthetic division problem.

Solution:

The given synthetic division problem is:

$3|\overline{3\quad -2\quad 2\quad 4}\\$

$\quad 6\quad 8\quad 20\\$

$\overline{3\quad 4\quad ?\quad 24}$

In synthetic division, we need to add first and second row to get the bottom row.

$3+0=3$

$-2+6=4$

$4+20=24$

Similarly,

$2+8=10$

Therefore, the missing value in the given synthetic problem is 10. Hence, the correct option is C.

a washer and a dryer cosr $873 combined. thenwasher cost$ $77 less than the dryer . what is the cost of the dryer.

Hitman42 [59]

Let the dryer cost x.

Then, the washer costs (x-77)

Together, they cost (x) + (x-77) = 873

2x-77 = 873 [subtract 77 from both sides]

2x = 796

x = 398

So the dryer costs $398
