Answer:
y = 2/3x - 1
Step-by-step explanation:
Find the slope:
2y = 3x - 5
2/2y = 3/2x - 5/2
y = 3/2x - 5/2
Slope is 3/2
In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.
Perpendicular equation:
y = 2/3x + b
b is going to be equal to the y intercept of the point they gave us, so -1.
Answer: y = 2/3x - 1
Cos A = adjacent/hypotenuse
Cos A = 9/26 = 0.346
Answer:

Step-by-step explanation:
Simplify 
We can simplify the expression by by using the quotient rule. Since the numerator is greater than the denominator and of similar terms, we'll subtract the denominator from numerator. This simply means that to divide two exponents with the same base, you keep the base and subtract the powers.
