I can't answer this because I don't know what she was starting with
Y = x + 3/4
x = y - 3/4
swap the variables:-
y = x - 3/4 (answer). Its a.
The answer is 29/34 your answer
Composing function is applying one function to the result of another and an arithmetic operation is when you add, subtract, multiply, or divide two functions.
Answer:
Option (4)
Step-by-step explanation:
Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).
Slope of XY (
) = 
= 
(
) = 
Similarly, slope of XZ (
) =
(
) = (-1)
Which should be (-1) if XY and XZ are perpendicular to each other.
Now we can say that XY and XZ are not perpendicular.
Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.
Option (4) will be the answer.
