Answer:

0,4,8

Step-by-step explanation:

We need to replace x with 1, 2, and 3 one by one in the given equations to find the value of y for each value:

y = 4*1 - 4 and y = 0 in this case

y = 4*2 - 4

y = 8 - 4 and y = 4 in this case

y = 4*3 - 4

y = 12 - 4 and y = 8 in this case

So the answer is

0,4,8

How do you rearrange the equation (2x) /(4pi) +((1-x) /2) =0 to solve for x?

USPshnik [31]

$\frac{2x}{4 \pi } + \frac{1-x}{2} =0 \\ 
 \frac{x}{2 \pi } + \frac{1-x}{2} = 0$
Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )

Use the quadratic formula <br> 9x^2+3x-1=0

ASHA 777 [7]

Answer:

9x2+3x−1=0

Step 1: Use quadratic formula with a=9, b=3, c=-1.

x= −b±√b2−4ac

x= −(3)±√(3)2−4(9)(−1)

2(9)

x= −3±√45

x= −1

What the heck do i do with this

Ad libitum [116K]

Use the law of cosines to find a: $a^2=b^2+c^2-2bc (cos(A))$

So to use the given numbers you get: $a^2=27^2+45^2-2(27)(45)(cos(53))$

Which would come out to equal about 35.94

so a=35.9
