Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form:
. Substitute
for x and 10 for y in the equation, then solve:

10 does equal 10, so this is a true statement. Option C is the right answer.
Im pretty sure you need to divide 155 by 4 or 48. try it and see what you get. then ask your teacher if you did it right. always ask questions.
Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2
___
Alternatively, you can simplify the given expression:

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
K is the midpoint of AB Correct answer
Step-by-step explanation:
Given AB = CD
<em>ADDING</em><em> </em><em>BC</em><em> </em><em>ON</em><em> </em><em>BOTH</em><em> </em><em>SIDES</em><em> </em>
<em>WE</em><em> </em><em>GET</em>
<em>AB</em><em>+</em><em>BC</em><em>=</em><em>CD</em><em>+</em><em>BC</em>
<em>THEREFORE</em><em> </em><em> </em><em>AC</em><em> </em><em>=</em><em>BD</em>
