The general form for a straight line is y = mx + c where m is slope and c is y-intercept.
Two lines are perpendicular when the product of their slopes = -1
Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2
So a line perpendicular to the given and has the same y-intercept is
y = (-7/3) x - 2
Answer:
x<-3
Step-by-step explanation:
-7x+6/3 >9
-7x+6 >27
-7x>27-6
-7x>21
-x>3
x<-3
7 because 7x4 is 28 and is u try to fit 8 it would be 32 so u can only fit 7
Answer:
AB = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
Step-by-step explanation:
The angle 25 is the starting point and adjacent is 4 and the unknown or we will call it x is the hypotenuse.
We will use CAH
Cos25 = 4/x
We need x by itself so
x = 4/cos25
Put in calculator and put to the nearest hundredth or 2 dp
