Answer:
D.
Step-by-step explanation:
When a line is perpendicular to another, their slopes will be opposite reciprocal. For example, 1 would be -1, -3 would be 
, and 
would be -5. The equation is written in slope-intercept form:
m is the slope, so find the equation with the opposite reciprocal of 3, 
:
is the only option with the correct slope, so the answer is D.
Answer:
<em>The expression is equivalent to 1,125</em>
Step-by-step explanation:
<u>Arithmetic Expressions</u>
It's given the word expression: "three squared times five cubed". It can be written in math form as:
Expanding the powers:
The expression is equivalent to 1,125
Since the shirt is 25 percent off your paying for 75 percent of the shirt. 0.75(36) is 27. The shirt will cost 27.00
You are right. Transitivity means, that:
if a = b and b = c, then a = c
(here a = x, b=5 and c = y).
The weight is proportional to the price. So if 10lb cost $18.24, quarter as much (2.5lb) would cost four times less($18.24÷4=$4.56).
