Answer:
2x + 3 = -7 ---> x = -5
4.5x - 7 = 20 ---> x = 6
-3x + 7 = 28 ---> x = -7
Step-by-step explanation:
2x + 3 = -7
2x = -10
x = -5
4.5x - 7 = 20
4.5x = 27
x = 6
-3x + 7 = 28
-3x = 21
x = -7

Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
[tex]c^{2} - b^{2} = a^{2}[/tex]
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
Answer:
30
Step-by-step explanation:
c=√a^2+b^2
a=√c^2-b^2 = √50^2-40^2 = 30

Solve for x

subtract 6 from both sides, then solve
|2x - 4| = 2 and |2x -4| = -2
2x - 4 = 2 2x - 4 = -2

2x = 6 2x = 2

D. there is a horizontal asymptote at y=-1
Answers
Answer:
The Y-intercept is -1
Step-by-step explanation:
M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.

C.

D.

Answers
Answer: A. [tex]2\times10^{-6}[/tex].
Step-by-step explanation:
Given: The diameter of bacterium = 0.0000029 meter
≈ 0.000002 meter [ with 6 decimal places]
[tex]=\dfrac{2}{1000000}=\dfrac{2}{10^6}[/tex]
[tex]=2\times10^{-6}[/tex] meters [[tex]\dfrac{1}{a^n}=a^{-n}[/tex]]
i.e. [tex]2\times10^{-6}[/tex] closest to 0.0000029.
Hence, the correct option is A. [tex]2\times10^{-6}[/tex].
