X = 3 --->  3*7 = 21 so 5x = 21   
7    5

5x = 21   this equals 4.2
5       5

Write the equation of the line that passes through the point P(4,3)And is perpendicular to the line y=-5x+2
Ray Of Light [21]

Answer:

y = 1/5x + 2 1/5

Step-by-step explanation:

since the slope of the line in the equation given is -5 the perpendicular slope to that will be the opposite reciprocal which is 1/5

Then plug x, y and m into y = mx + b

3 = 1/5 (4) + b

3 = 4/5 + b

2 1/5 = b

Write equation

y = 1/5x + 2 1/2

Find the missing side lengths. leave your answers as radicals in simplest form.
Murrr4er [49]

Answer:

x = 4 , y = 2

Step-by-step explanation:

Using the sine / tangent ratios in the right triangle and the exact values

sin60° = \frac{\sqrt{3} }{2} and tan60° = \sqrt{3} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{2\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x \sqrt{3} = 4\sqrt{3} ( divide both sides by \sqrt{3} )

x = 4

and

tan60° = \frac{opposite}{adjacent} = \frac{2\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

y \sqrt{3} = 2\sqrt{3} ( divide both sides by \sqrt{3} )

y = 2
