4x-6y=12
for ax+by=c
slope = -a/b hence , slope = 2/3 is the answer

4x - 6y = 12
6y = 4x - 12
y = 4/6x - 12/6
y = 2/3x -2

Answer : Slope = 2/3

For the line segment whose endpoints are A(0,0) and B(4, 3), find the x value for the point located

Crank

Answer:

Step-by-step explanation:

The distance between A and B is given by the Pythagorean Theorem:

$= \sqrt{(4-0)^{2}+(3-0)^{2}} = 5$

The angle of the line segment is:

$\theta = \tan^{-1}\left(\frac{3-0}{4-0} \right)\\\\\theta \approx 36.870^{\circ}$

The x-coordinate of the point is:

$x = 0 + \frac{2}{3}\cdot (5) \cdot \cos 36.870^{\circ}\\\\x = 2.667$

x≅ 2.7

For any number n>1 is |(3/4+2/3i)^n|

sasho [114]

The for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

$= \rm |(\dfrac{2}{3}+\dfrac{3}{4}i)^n|\\\\\\= \rm |(\dfrac{8+9i}{12})^n|\\\\\\= \rm |\dfrac{(8+9i)^n}{12^n}|\\\\$

Here n>1

Plug n = 2

$= \rm |\dfrac{(8+9i)^2}{12^2}|\\\\$

= 145/144

= 1.0069

Which is greater than 1.

Thus, the for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.

In April, Senator Smith’s approval rating dropped from 62% to 57%. In May, the approval rating decreased by another 8 percentage

Keith_Richards [23]

Senator Smith's percentage rating must increase by 13% in other to undo the previous decreases.

Initial rating = 62%

April rating = 57%

May rating = 57% - 8% = 49%

Final rating after decrease = May rating = 49%

In other to return to initial rating :

Initial rating - Final rating

62% - 49% = 13%

Hence, in other to undo the decrease in April and May rating, Senator Smith's percentage rating must increase by 13%
