Answer
In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
Step-by-step explanation:
Going off the idea that this is 4/(y+2) - 9/(y-2) = 9/(y^2-4), let's first rewrite y^2-4 in the form of a^2-b^2, where a=y and b=2.
y/(y+2)-9/(y-2)=9/(y^2-2^2)
Now, use difference of squares: a^2-b^2=(a+b)(a-b)
4/(y+2)-9/(y-2)=9/((y+2)(y-2))
Multiply both sides by the Least Common Denominator: (y+2)(y-2)
4(y-2)-9(y+2)=9
Then keep on simplifying until you get your answer
-5y-26=9
-5y=9+26
-5y=35
y=35/-5
y=-7
Yay! Our answer is y=-7!
Answer:
<h2>A. Switch the inequality sign</h2>
Step-by-step explanation:
When multiplying, you must switch the inequality sign. This is also true when dividing.
EXAMPLE 1:
-4r < -21
Note: We reversed the inequality sign when we divided by -4
r > 5 1/4
EXAMPLE 2:
x/-5 <u>></u> 7
Note: We reversed the inequality sign when we multiplied by -5
x <u><</u> -35

Answer:
13, 13√3, 26
Step-by-step explanation:
30 60 90 right triangle
Ratio of short leg : long leg : hypo = a : a√3 : 2a
Given short leg = 13, so long leg = 13√3 and hypo = 13 * 2 = 26
Answer:
13, 13√3, 26
Answer:
Calculate the determinant. Calculate the matrix of cofactors. Transpose the matrix of cofactors to obtain the adjugate matrix. Divide each entry of the adjugate matrix by the determinant to obtain the inverse.
