A line is y=12. what is the slope of a line perpendicular to this

1 answer:

7 0

Writing this equations in slope intercept form we get y=0x+12, from which we see the slope I'd 0. the slope of perpendicular lines are negative reciprocals. the negative receipt of 0 would be -1/0, but we know that division by 0 is undefined. there for the slope of the lines are 0 and undefined. sometimes it is useful to say the slope of a vertical line is infinity.

The 10th term of an a.p is -27 and the 5th term is -12 .find the first term?

horsena [70]

Step-by-step explanation:

$a_{10} = - 27... (Given) \\\\\therefore a + 9d = - 27...... (1)\\\\a_{5} = - 12... (Given) \\\\\therefore a + 4d = - 12.......(2)\\\\$

Subtracting equation (2) from equation (1)

$a + 9d-( a + 4d )= - 27-(-12)\\\\\therefore a +9d - a-4d = - 27+12\\\\\therefore 5d = - 15\\\\\therefore d = \frac {- 15}{5}\\\\\huge \orange {\boxed {\therefore d = -3}} \\\\$
