Let g represent gallons of water and let L represent loads.

Here, the gallons of water varies directly with the number of loads, thus we have:

g ∝ L

Now introduce a constant k:

**g = kL**

65 gallons is used to wash 5 loads, thus we have:

65 = k * 5

Let's solve for k:

65 = 5k

Divide both sides by 5:

[tex]\begin{gathered} \frac{65}{5}=\frac{5k}{5} \\ \\ 13=k \end{gathered}[/tex]To find the amount of water that will be used to wash 8 loads, we have:

g = kl

We are to find g, substitute 13 for k and 8 for l:

g = 13 x 8

g = 104

Therefore, to wash 8 loads, 104 gallons of water is needed.

**ANSWER:**

**104 **

So, we have:

BC = 20; CD = 15. What is the value of BD − AC.

**Answer:**

BD - AC = 0

**Step-by-step explanation:**

BC = 36 , CD = 15 and BD = x

As these are forming right angled triangle,

Using Pythagorean theorem,

Taking square root on both sides

As the given shape is rectangular, the sides parallel to each other will have same values.

AB = 15 , AD = 36 and AC = x

Now,

BD - AC = 39 - 39 = 0

**Answer:**

1 These 5 main features are the title, scale, points, labels, and line.

2. Relations are a group of ordered pairs from one set of objects to another set of objects while functions are relations that connect one set of inputs to another set of outputs. So all functions are relations while all relations are not functions.

3. To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

4. The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. In other words, Pick two points on the line and determine their coordinates.

5. To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'. To find the y-intercept, plug 0 in for 'x' and solve for 'y'.

6. An example of a linear equation is: 2x + y - 3 = 0. It can be written in the standard form, the slope-intercept form, and the point-slope form. Here we mainly used the slope-intercept form y=mx+c y = m x + c . To write linear equations find the slope and y-intercept and then substitute these values into the equation.
