So you got
z²+y²=25² and
17²+x²=z²
x²+6²=y²
nice, so we have z² and y² all in terms of x
17²+x²+x²+6²=25²
2x²+289+36=625
2x²=300
x²=150
x=5√6
if we input back to find y and z
17²+x²=z², 287+150=z², √439 =z
x²+6²=y², 150+36=y², √186=y (not simplifying because no graphing calculator, so just eimplify yourself)
The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
Let's use our trigonometric skills to solve for this one:
Answer:
Step-by-step explanation:
The expression -9 + x*2 - 3x*2 + 4x has the following terms:
-9, x^2, -3x^2 and 4x. Please note: x^2 is correct if you meant "the square of x."
a) there is only one constant term; it is -9.
b) there are two terms involving x^2: x^2 and -3x^2. Combining them results in -2x^2.
c) there is only one term involving x: It is 4x.
d) -9 + x*2 - 3x*2 + 4x becomes -2x^2 + 4x - 9. Again, please use " ^ " to indicate exponentiation.
