In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
 
  30x+ 8 = 128

If you subtract 8 from both sides and then divide by 30 you'll find that x=4.

The statements that are true about the given points on the line are; Options B, C and D

<h3>How to identify points on a Plane?</h3>

A plane is defined by a line and a point outside of it. Meanwhile, a line is defined by two points. Thus, whenever we have 3 non-collinear points, we can define a plane.

Let us check each of the given options;

A) There are exactly two planes that contain points A, B, and F;

If these points are collinear, they can't make a plane and If they are not collinear, they define a plane.

Since we can't make two planes with them, then the statement is false.

B) There is exactly one plane that contains points E, F, and B;

Due to the same reasoning in part A, the statement is true assuming the points are not collinear.

C) The line that can be drawn through points C and G would lie in plane X;

The statement is true because both points C and G lie on plane X, and as such the line that connects them also should lie on the same plane.

D) The line that can be drawn through points E and F would lie in plane Y; Similar to above, this statement is true.

E) The only points that can lie on plane Y are points E and F.

This statement is false because infinite points can lie on a plane.

In the standard (x, y) coordinate plane, what is the y-intercept of the line given by the equation <img src="https://tex.z-dn.ne
Agata [3.3K]
<span>the y-intercept will be \frac{8}{5}

</span>the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.

to get the y intercept, we need to transform  into the line equation, and caculate out b.

3x + 5y = 8
so 5y = 8 -3x
then y = <span>\frac{8}{5} - <span>\frac{3}{5}x
which  means that <span>\frac{8}{5} = the y intercept.</span></span></span>
