Answer:

Step-by-step explanation:
We have the equation:

Since their bases are the same, the exponents must be equivalent. So:

Solve for r, subtract 2r from both sides:

Divide both sides by -5:

So, the value of r is -3/5.
And we're done!

Answer:
X = 80
Step-by-step explanation:
Add 35 To Both Sides
X - 35 + 35 = 45 + 35
Simplify
X = 80

Just put the x number for x and solve equation
Answer:
(x, y) ⇒ (-x, -y)
Step-by-step explanation:
There are a couple of ways you can go at this.
1) Rotation by 180° in either direction is the same as reflection across the origin. That reflection is identical to reflection across both the x- and y-axes, in either order, so negates both coordinates. The transformation rule is ...
(x, y) ⇒ (-x, -y)
__
2) The rule for a general rotation by angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
For α = 180°, sin(α) = 0 and cos(α) = -1. This makes the rule for rotation by 180° be ...
(x, y) ⇒ (-x, -y)
