Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = =
= -
, then
y = - x + c
the line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - x + 6 ← equation in slope- intercept form
multiply through by 2 to clear the fraction
2y = - 3x + 12 ( add 3x to both sides )
3x + 2y = 12 ← equation in standard form
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.
