Yes you are correct B is the right answer
One of the missing angles is 45degrees 64+71=135 then subtract from 180 since it is a triangle. Then 64 are vertical angles with the one across from it which stays the same. The last angle would be 64+56=120 and 180-120=60 which would be the last angle. Hope this Helps... Juan
Graph the equation. There are multiple ways to do this.
You can create a table of values, use the quadratic formula, convert from standard to vertex form.
If you're trying to factor, you'll eventually notice this thing cannot be factored (no roots!). If you use the quadratic formula, you will get an imaginary answer (no roots!)
If you go in the route of picking points and coming up with a table of values you'll get a graph like this (see attachment) Notice there are no roots! because the graph never ever hits the x-axis
Answer:
D
Step-by-step explanation:
128/2 = 64
The squareroot of 64 = 8
That means that only C or D could be true; 8 is in the numerator not the denominator.
Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.
There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.
Answer 8sqrt(y)/x
