First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5

Divide -8x by -8 which leaves you with x and you have to do it to both sides so divide 60 by -8 which leaves you with -7.5
and continue doing all algebraic equations that way following the two rules:
1) to get rid of a number do its opposite
2)whatever you do to one side do to the other

The length of a room is 16.40 m, its width is 4.5 m, and its height is 3.26 m. what volume does the room enclose?
AVprozaik [17]
<span>According the information given we understand that the room is a regular rectangle, We know that volume = lenght * widht * height, so we start by calculate the room area as length by width, that is 16.4 * 4.5 = 73.8 square metres. Then with 3.26 metres of height, the total volum will 73.8 * 3.26 = 240.58 cubic metres.</span>

Super urgent!<br><br> Solve the equation for all real values of x. 3tan^2 = sqrt3 tanx
lutik1710 [3]

f(x) = tan2(x) + (√3 - 1)[tan(x)] - √3 = 0

tan2(x) + √3[tan(x)] - tan(x) - √3 = 0

Factor into

[-1 + tan(x)]*[√3 + tan(x)] = 0

which means

[-1 + tan(x)] = 0 and/or [√3 + tan(x)] = 0

Then

tan(x) = 1

tan-1(1) = pi/4 radians

For the other equation

[√3 + tan(x)] = 0

tan(x) = -√3

tan-1(-√3) = -pi/3

so that

x = pi/4 or -pi/3 in the interval [0, 2pi]
