The exponent of 12 tells of how many prizes to count to the left of the decimal. Another example of how a scientific notation can make numbers easier to read is the diameter of a hydrogen atom, which is about 0.00000005 mm, and in Scientific notation is 5x10-8 5x10 -8mm.
72 is the correct answer I think
When a () is right next to a number such as the problem you have it means to multiply. so 77 times -1 equals -77. so i'm not sure why -77 isn't one of your answer choices. maybe you mistyped something?
Answer:
I can't graph on here but to graph you start at the starting point which is -1 in the y-axis. So we start at -1 on the y-axis then we carry out the slope which is -1. Because the slope is negative the graph will be negative so you move down 1 and right 1 continuously.
Step-by-step explanation:
To graph the line you have to put it in y = mx + b form
So first let's distribute
y + 2 = -1x + 1
Subtract 2 from both sides
y = -1x - 1 OR y = -x - 1
