aliina [53]

Given:

$5|x-3|+3>7$

Aim:

We need to find the value of x.

Explanation:

Subtract 3 from both sides of the equation.

$5|x-3|+3-3>7-3$

$5|x-3|>4$

Divide both sides of the equation by 5.

$\frac{5}{5}|x-3|>\frac{4}{5}$

$|x-3|>\frac{4}{5}$

Square both sides.

$(x-3)^2>(\frac{4}{5})^2$

$(x-3)^2>\frac{16}{25}$

$x^2-6x+9>\frac{16}{25}$

multiply

$x^2-6x+9>\frac{16}{25}$

Write the expression 2i^15-i^7 in the standard form a + bi

elixir [45]

$\bf 2i^{15}-i^7\qquad 
\begin{cases}
i^2=\sqrt{-1}\cdot \sqrt{-1}\implies \sqrt{(-1)^2}\implies -1\\\\
i^4=i^2\cdot i^2\implies -1\cdot -1\implies 1
\end{cases}\\\\
-----------------------------\\\\
2i^{4+4+4+2+1}-i^{4+2+1}\implies 2i^4i^4i^4i^2i^1-i^4i^2i^1
\\\\\\
(2\cdot 1\cdot 1\cdot 1\cdot -1\cdot i)-(1\cdot -1\cdot i)\implies -2i-(-i)
\\\\\\
-2i+i\implies -i\implies \boxed{0-i}$

How do I know when a slope declines or ascends?

babunello [35]

How to tell when a slope declines or ascends is to see if the line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the botto left and goes towards the top right.

Answer: If the line is a positive slope, y increases when x increases too. So the line on the graph starts at the bottom left and goes towards the top right ( than it's positive)
