Answer:
○ C. The lines are perpendicular.
Step-by-step explanation:
In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:
− to +}
> OPPOSITE
+ to −}
MULTIPLICATIVE INVERSE [RECIPROCAL]

If pounds was x
a. 0.65x is the equation.
2 pounds would cost $1.30
b. 0.65x-0.05x is the equation.
Answer:9
Step-by-step explanation:
If you meant -3x then the answer is (2,12)
Using the properties of inequalities:
Subtract -2 from each side of the inequality -2 + x > 10
Remember -2 - -2 becomes -2 + 2 = 0 <u>- -2 + x > --2
</u>10 - -2 becomes 10 + 2 =12<u /> 0 + x > 12
So the final solution would be x > 12.
Therefore x would have to be all numbers greater than 12.
