Answer:
The format of the equation of a line is y=mx+c so in order to know whether which line is perpendicular to line y=5x-9, gradient of y=5x-9,which is 5,has to multiply by another gradient to get -1.[in short m1×m2=-1]
So the equation perpendicular to line y=5x-9 has a gradient of -1÷5=-1/5
1/3, because the probability in the cube is 1/6, and there are 2 numbers less than 3. So, 2/6 and simplify 2/6 to 1/3.
Answer:
x = (y - 4)/7
Step-by-step explanation:
Subtract 4 from both sides to get:
y - 4 = 7x
Then, divide both sides by 7 to get:
(y - 4)/7 = x

Answer:
13
Step-by-step explanation:
note: your question doesn't contain enough information
so I took it as midsegment
my answer is correct if it's midsegment
X= 180 - (55 + [180 - 105])
x = 180 - (55 + 75)
x = 180 - 130
x = 50
