We multiplied by 10^1 above, because there is 1 repeating digit. The power of 10 we use matches the number of repeating digits.
Answer:
y = 6
Step-by-step explanation:
[] We can plug in our x value of -3, from the coordinate point, and solve for y.
y = 3 - x
y = 3 - (-3)
y = 3 + 3
y = 6
[] We can also graph the equation, and find the point where x = -3

To solve this, we need to know what 501,800,000 is in scientific notation. We can figure out what <span>501,800,000 is in scientific notation by first figuring out what we're going to be multiplying by ten to the power of x. We're going to multiply 5.018 by 10 to the power of x because it 5.018 is the what happens when you put a dot after the first number and then get rid of all the zeroes after the last non-zero number (which is what scientific notation is about). Now we need to figure out what we need to multiply 5.018 by to get to </span>501,800,000. We need to multiply 5.018 by 
to get to 501,800,000, so <span>501,800,000 in scientific notation is 5.018 </span>· . Since we now see that the two values are not equal, the answer to the question is false.
