Answer:
C. x=5 units.
Step-by-step explanation:
In right triangle ABC, the height BD is the geometric mean of the segments AD and DC.
Hence,
![BD^2=AD\cdot DC,\\ \\10^2=x\cdot 4x,\\ \\100=4x^2,\\ \\x^2=25,\\ \\x=5\ un.](https://tex.z-dn.net/?f=BD%5E2%3DAD%5Ccdot%20DC%2C%5C%5C%20%5C%5C10%5E2%3Dx%5Ccdot%204x%2C%5C%5C%20%5C%5C100%3D4x%5E2%2C%5C%5C%20%5C%5Cx%5E2%3D25%2C%5C%5C%20%5C%5Cx%3D5%5C%20un.)
Answer:
x ≥6
Step-by-step explanation:
Given the product:
√(x-6)*√(x+3)
The function has to be defined if x ≥0
Hence;
√(x-6)*√(x+3)≥0
Find the product
√(x-6)(x+3)≥0
Square both sides
(x-6)(x+3)≥0
x-6≥0 and x+3≥0
x≥0+6 and x ≥0 - 3
x ≥6 and x ≥-3
Hence the required inequality is x ≥6
Hi okay so if the original coords are a=(-2,0) b=(-3,-2) and c=(-5,-2), if one of the coords on the dilated triangle are (7,3), you apply that to the rest. so i think a=(7,3) b=(10.5,7) c=(17.5,7)but i’m not sure cause it says the constant is 4 but if you apply the constant of (7,3), the constant is -3.5. if you apple the constant of 4, the answers don’t really make sense.
answer: a=(7,3) b=(10.5,7) c=(17.5,7) i think
this question actually doesn’t really make sense at all. but i hope this helps lol.
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.
![2x - x = 15](https://tex.z-dn.net/?f=2x%20-%20x%20%3D%2015)
Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.
![x = 15](https://tex.z-dn.net/?f=x%20%3D%2015)
