Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4
<u>Solution:</u>
Given that, Tammy uses 1 3/4 cups of laundry detergent per load.
When she was finished doing laundry one day.
She noticed that she had used 7 cups of laundry detergent.
We have to find how many loads did she do?
Now, we know that, Total cups used can be written as:
<em> </em>number of loads x number of cups per each load = total cups used.
Hence, the number of loads are 4.
Answer:
y = x + 46
Step-by-step explanation:
When writing an equation of a line, keep in mind that you always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:
1. 2 sets of ordered pairs (x, y)
2. Slope (m)
3. Y-intercept (b)
First, choose two pairs of coordinates to use for solving the slope of the line:
Let (x1, y1) = (0, 46)
(x2, y2) = (1, 47)
User the following formula for slope
Plug in the values of the coordinates into the formula:
Therefore, the slope (m) = 1.
Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, 46) is the y-intercept. Therefore, b = 46.
Given the slope, m = 1, and y-intercept, b = 46, the linear equation in slope-intercept form is:
y = x + 46
