How do you work a 45-45-90 angle in math I have a test tomorrow and I would really appreciate if someone answered.

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

(05.08a)triangle abc is transformed to similar triangle a′b′c′ below: a coordinate plane is shown. triangle abc has vertices a at 2 comma 6, b at 2 comma 4, and c at 4 comma 4. triangle a prime b prime c prime has vertices a prime at 1 comma 3, b prime at 1 comma 2, and c prime at 2 comma 2. what is the scale factor of dilation? 1 over 2 1 over 3 1 over 4 1 over 5

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
