Answer:

y=2x-3

Step-by-step explanation:  

The slope-intercept form of the original equation would be y=3/8−x/2

Therefore, the slope of the perpendicular line would be m=2

Then, the y-intercept would be 7=(2)x(5)+a

A=-3

Answer:

y=2x+3

8=1/3(a+5)<br><br> Please help and thank you :)
s344n2d4d5 [400]

Answer:

a=19

Step-by-step explanation:

First we have to distribute the parenthesis; multiply (a+5) by 1/3

8=1/3*a+1/3*5

Now we just solve the equation regularly

8=1/3a+5/3

8-5/3=1/3a

6 1/3=1/3a

a=19

The diagram shows rays of light from a point source, P, that reach a detector, D, along two paths. One path is a straight line,
tatiyna
This can solved using the cosine law which is:
c² = a² + b² - 2ab cos θ
Using the values given from the problem
6² = b² + b² - 2bb cos 112.62
And solving for b
36 = 2b² - 2b² cos 112.62
b = 3.6

The answer is the 3rd option.
