Answer:
We conclude that the slope of the line represented by the equation
would be:
Step-by-step explanation:
We know that the slope-intercept of the line equation is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
here
Given the equation
![y\:=\:\frac{4}{5}x-3](https://tex.z-dn.net/?f=y%5C%3A%3D%5C%3A%5Cfrac%7B4%7D%7B5%7Dx-3)
comparing with the slope-intercept of the line equation
The slope = m = 4/5
Thus, we conclude that the slope of the line represented by the equation
would be:
Well if you need the roots one of them is -1
because f(1) = -1-9-15+25 = 0
Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))
Answer: y = 3
<u>Explanation:</u>
Parallel to the x-axis means slope (m) = 0
Input the given point (1, 3) and the slope into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 3 = 0(x - 1)
y - 3 = 0
y = 3
<em>Answer:</em>
94.25m
<em>Explanation:</em>
× ![\frac{19.5}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B19.5%7D%7Bx%7D)
Solve for x.
(cross multiply & divide)
4.5 × 19.5 = 282.75
282.75 ÷ 3 = 94.25
