If the equation is -(2/3) x - (1/4) y = 1/3, it is a straight line, so you can use some special points to identify the graph.

It is easier is you solve the equation for y:

(1/4)y = - 1/3 - (2/3) x

y = (-4/3) - (8/3)x

That is the slope -y-intercept form of the equation.

That means that the slope is -8/3, and the y-intercept is -4/3.

Use this points to identify the graph:

x = 0 => y = - 4/3 ---> (0, - 4/3)

y = 0 => x = - 1/2 -----> (-1/2, 0)

Now you can punt those two points on the graph and draw the line that joins them.

With this procedure you can find the graph of any straight line.

The value of a truck after t years is represented by the function f(t)=22,200(0.92)t .
n200080 [17]
<u>ANSWER:</u>
<span>The initial value of the truck is $22,200
</span>
<u>EXPLANATION:</u>
For the given function 
<span>
     f(t) = 22,200(0.92)^t

We know that at t = 0, we have

</span>    f(0) = 22,200(0.92)^0 = 22,200
<span>
which is the value of the truck initially. So, the correct answer is

</span>The initial value of the truck is $22,200

What is the answer to -7=-12 (-2)+B please help!
insens350 [35]
I would solve it for B, but that's just what I think. So you would do -12 time -2 which is 24, then subtract 24 from both sides so that you would get B=-31

What is the value of x?<br><br> Enter your answer in the box. <br><br> x = ___
lapo4ka [179]
Answer:

x=8

Explanation:

The picture tells us that the triangle is equilateral (this means that each angle is 60°). We can assume this because each side has been marked with the same line.

Because each angle is equal to 60°, this means that:

7x+4=60

Now solve for x:

7x=56
x=8
