Answer:
The value of the expression at b = -2 is thus -6
Step-by-step explanation:
We have been given the expression;

and we are required to evaluate the expression for b = -2
We simply substitute b with -2 in the given expression and simplify;

Answer:
The new coordinates are (-11, -35)
Step-by-step explanation:
When reflecting across the x-axis, you are just the Y. value. It is the opposite due to the fact that if you're moving something across the horizontal x-axis, it's actually the vertical height changing. So, you just inverse the Y value to its' negative or positive reciprocal.
Answer:
The last one, angle D equals to angle T
Step-by-step explanation:
Using the theorem of the triangle we know that the total number measure of the angles is 180 degrees. Therefore, solving the second triangle will give us that the angle T is equal to 60.
This is equal to angle D.
Hope this helps.
