Answer:
Your answer is 7
Step-by-step explanation:
The two lines are the same length, so set the lengths equal to each other.
5x-3=11-2x
add 2x
7x-3=11
add 3
7x=14
divide by 7
x=2
Then you just plug x in
5(2)-3
multiplication first
10-3
subtraction
7
That is your answer
Answer:
Step-by-step explanation:
(8 - 8i) + (1 + 6i)
8 + 1 - 8i + 6i
9 - 2i
Answer:
Step-by-step explanation:
tanA = sinA/cosA = (4/7)/(3/7) = 4/3
Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1
