Yes that's right - that means that if you take one triangle and multiply all its sides by the SAME factor, you'll end up with the other triangle. It's the same shape, just a different size.
Answer:
Step-by-step explanation:
The vertex can be located most easily by completing the square of
f(x) = -X^2 - 2x - 1 (which is equivalent to -(x^2 + 2x + 1). The latter expression can be rewritten as -(x + 1)^2, which indicates that the x-coordinate of the vertex is -1. The corresponding y-value is 0. Vertex is at (-1, 0).
The function is increasing for x < -1 and decreasing for x > -1.
The domain of the function is "all real numbers."
The range is (-infinity, 0)
Answer:
x = 4
Step-by-step explanation:
4(x-9)=3x-8x
Follow distributive property
4x - 36 = 3x - 8x
Combine like terms
4x - 36 = -5x
Subtract 4 from both sides
-36 = -9x
Divide both sides by -9
x = 4
You square root the whole problem not both of them
Here's the equation:
0.90(5.99) + 0.04(0.9(5.99))
We can simplify this:
0.90(5.99) + 0.036(5.99)
5.391 + 0.21564
5.60664
We can round:
It will cost about $5.61
