Volume = rule area × height

Volume = ( 5 × 8 ) × 2

Volume = 40 × 2

Volume = 80 cm^3

Determine whether the lines are parallel, intersect, or coincide<br> y=1/3x+4 <br> x-3y=-12
adell [148]

The slopes of two lines are equal which means that the lines are parallel.

Further explanation:

The slopes of lines are used to find the relationship between two line.

  • If two lines are parallel, then their slopes will be equal.
  • If two lines are perpendicular, the product of slopes of both lines will be -1

The standard form of equation of line is:

y=mx+b

The coefficient of x is the slope here.

y=1/3x+4

Let m1 be the slope of first line:

m_1=\frac{1}{3}

x-3y=-12\\-3y=-x-12\\-3y=-1(x+12)\\3y=x+12\\\frac{3y}{3}=\frac{x+12}{3}\\y=\frac{x+12}{3}\\y=\frac{x}{3}+\frac{12}{3}\\y=\frac{1}{3}x+4

Let m2 be the slope of second line

m_2=\frac{1}{3}

We can see that:

m_1=m_2

The slopes of two lines are equal which means that the lines are parallel.

I need to know what formula to use in order to figure out the problems. You do not have to solve, I can do that. I just need a f
REY [17]

Answer:

The equation 4x -6y = 12 is in

"standard" form. if you modify it to be in the "slope intercept" (y=mx+b)

it will be modified to help more easily graph

y= 2/3 x -2 is the same equation in slope intercept (graphing) form...

here you can see that slope (rise over run) is positive and is 2/3 thus it goes from lower left to upper right... the "y-intercept" (the B) is at "-2" thus the line intercepts the y axis at -2

you can find the x and y intercepts by replacing the x with a 0 to get  the y intercept, and then replacing the y with a 0 to get the x intercept

Step-by-step explanation:

How to do this equation
dezoksy [38]
5/(6x-2)=-1/(x+1) 
5*(x+1)=-1*(6x-2)
5x+5=-6x+2
11x+5=2
11x=-3
x=-3/11

Hope this helps :)
