Step-by-step explanation:
Given
f(x) = x - 5
When x = 12
f(12) = 12 - 5
= 7
45 Degrees on each side means it is equal, for an "equilateral" triangle.
Answer:
see explanation
Step-by-step explanation:
The exponents can only be added if the bases are the same
Here one base is 12 and the other is 11
So the rule of addition is not applicable.

Plz don't delete...cuz im tryna help '-'
Step-by-step explanation:
25r²-100=0
25r^2 = 100
cuz the (-) will turn (+) when taken to the other side of the (=) sign
25r^2 = 100
<em>divide both sides by 25</em>
<em>divide both sides by 25 then we get </em>
r^2 = 4
r^2 = 2^2
<em>now take the sqare roo</em><em>t</em><em> of both sides</em>
r = 2
EXAMPLE
Find the distance between the points A(−4, −3) and B(5, 7).
SOLUTION
In this case, x1 = −4, x2 = 5, y1 = −3 and y2 = 7.
AB2 = (x2 − x1)2 + (y2 − y1)2
= (5 − (−4))2 + (7 − (−3))2
= 92 + 102
= 181
Thus, AB =
Note that we could have chosen x1 = 5, x2 = −4, y1 = 7 and y2 = −3 and still obtained the same result. As long as (x1, y1) refers to one point and (x2, y2) the other point, it does not matter which one is which.
