Answer:
y = -2x + 16.
Step-by-step explanation:
The slope of the perpendicular line = -1 / slope of the given line
= -1 / 1/2 = -2.
Using the point slope form of the equation of a straight line:
y - y1 = m (x - x1)
y - 8 = -2(x - 4)
y - 8 = -2x + 8
y = -2x + 16 is the required equation.
Answer:
3
Step-by-step explanation:
-7x + 12 is not an equiv. expression because one of the - signs in the original expression has been changed to +.

Answer: 9/50</h3>
Explanation:
Any percentage converts to that number over 100.
So 18% would convert to 18/100
We then reduce the fraction by dividing each part by the GCF 2
18/2 = 9
100/2 = 50
The fraction 18/100 fully reduces to 9/50
Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
