The best choice is A)
when you add a zero, it does not count on a decimal, so,
1.9, 1.90, 1.900.
The total weight is 2 1/2 lbs
Rock A is 1/7 of the total weight....so it is 1/7 of 2 1/2 lbs..." of " means multiply
1/7 * 2 1/2 =
1/7 * 5/2 =
5/14 lbs <==
Answer:
Step-by-step explanation:
First, we need to find the y-intercept. The y-intercept is the intersection of the point on the y-axis. We can clearly tell that the y-intercept is 1. The slope is definitely 0 because it shows a straight line.
Hence, the equation is y = 1.
Please check out my graph to support my reasoning.
Answer:

Step-by-step explanation:
To find the equation of a line using slope and a point, first use the slope to create the basic line using the slope and work from there.
For instance, the base equation here is

This line passes through the point (0, 0).
You can then plug in a value for x. In this case, use the value of 3, as it corresponds with your question.

A point on the line of y = 2x would thus be (3, 6).
To make the y-value equal -3, you must then subtract from the original equation. There are 9 units between 6 and -3, so you must subtract nine units in the equation. You should get this at the end:
