Answer:
x = 2
Step-by-step explanation:
The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.
(x +4)² = (2x -1)(2x -1 +9)
0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)
0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)
This has solutions x = -4 and x = 2. Only the latter works in this geometry.
x = 2
Answer:
First blank: 5
Last blank: 20
Step-by-step explanation:
Going by the hint that is shown:
c = 1
r = 5
and
c = 4
r = 20
Hope this helps!
9_>x>_-1
- x would have to be less than or equal to 9, but greater than or equal to -1. the symbols for the greater than or equal to is the > with a line under it (in case you didn’t know) and same with the less than or equal to
Part A:The original brand was 12$ each and the new one is 8$ each.
12-8=4
Part B:she will save 16$ each month because y=12*4 and y=8*4 is 16$
