Answer:
<h2><u><em>
8x -2</em></u></h2>
Step-by-step explanation:
Subtract:
-6x-3 from 2x-5
2x - 5 -(-6x - 3) =
2x - 5 + 6x + 3 =
8x -2
Answer:
B and D
Step-by-step explanation:
For a linear equation, the degree is 1.
For y=x² , the degree is 2, so it is not linear.
For y=2x, the degree is 1, so it is linear.
For y=4/x----->xy=4, the degree is 2, so it is not linear.
For y=x/4, we have 4y=x, the degree is still 1, this is also linear.
The correct options are B and D.
-6.75 is your slope because it has an "x" behind it and the y-intercept is 8.54 since it doesn't have the "x."
Symmetry can be determined visually in a graph. If both graphs are mirror-image of each other, then both of the equations are symmetric. But, you can also determine it analytically through testing the symmetry. These are the rules:
If
f(r, θ) = f(r,-θ), symmetric to the polar axis or the x-axis
f(r, θ) = f(-r,θ), symmetric to the y-axis
f(r, θ) = f(-r,-θ), symmetric to the pole or the origin
Test for symmetry about the x-axis
f(r,θ): r=4 cos3θ
f(r,-θ): r = 4 cos3(-θ) ⇒ r = 4 cos3θ
∴The graph is symmetric about the x-axis.
Test for symmetry about the y-axis
f(r,θ): r=4 cos3θ
f(-r,θ): -r = 4 cos3θ
∴The graph is not symmetric about the y-axis.
Test for symmetry about the origin
f(r,θ): r=4 cos3θ
f(-r,-θ): -r = 4 cos3(-θ) ⇒ r = -4 cos3θ
∴The graph is not symmetric about the origin.
Use u subsitution
the derivitive of eˣ+2 is eˣ
u=eˣ+2
du/dx=eˣ
du=eˣdx
we see a eˣdx in the problem
sub du for that and u for eˣ+2
remember
sub eˣ+2 for u
don't forget to add a constant since the derivitive of a constant is 0
the original function is
where C is a constant
