Answer:
4x^2+16x+5
Step-by-step explanation:
(6x^2+7x)+(5-2x^2+9x)
6x^2-2x^2+7x+9x+5
4x^2+16x+5
For this problem, we are given a parallelogram with a diagonal drawn, inside it there are markings for a few angles. We need to determine the unknown angles.
Opposite sides of a parallelogram are parallel, this means we can treat the diagonal as a transversal line that crosses two parallel lines. Since this is the case, the angles 33º and xº are alternate interior angles and have the same length:

The opposite angles in a parallelogram are congruent, therefore:

The sum of internal angles is 360º, therefore we have:

The value of x is 33º, the value of y is 38º and the value of z is 109º.
Answer:
Step-by-step explanation:
Given that a curve in polar coordinates is given by:
r=9+3cosθ
a) At point P, we have

Substitute to get

b) Cartesian coordinate is

c) At the origin r =0
when r =0
we have

Since cos cannot take values as -3 it doe snot pass through origin.
Answer:
the 3rd one x+2=5
Step-by-step explanation:
Why?
because you are going from small # to a bigger # so you know you are adding
there is 2 there and it says that it = 5
(0,4)(2,-3)
slope = (-3 - 4) / (2 - 0) = -7/2
