The answer is x=9
Explanation: x + 16 = x^2 - 8x +16
x = x^2 - 8x
9x - x^2 = 0
X x (9-x) = 0
Answer:
This is for Sine Cosine and Tangent: triangle ABC, B is a right angle, the length of side AB is 12, the length of side BC is 5, the length of side AC is 13.
Find Sin of A, Cos of A, Tan A, Sin of C, Cos of C, and Tan of C.
Triangle XYZ, Y is a right angle, the length of XY is 20, the length of YZ is x, the length of XZ is 29.

Answer:
Step-by-step explanation:
(0,2). y=mx+b or 2=-2 × 0+b, or solving for b: b=2-(-2)(0).
There are 45C4 = 148,995 ways to choose 4 calculators out of a group of 45.
There are 33C4 = 40,920 ways to choose 4 calculators that are not defective.
The probability that at least one is defective is (148,995 -40,920)/148,995 ≈ 0.725.
Answer:
One solution: (2.5,0)
Step-by-step explanation:
We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.
