Just treat i like any other variable, and combine like terms. Hope that helps!
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 19x + 57 ← is in slope- intercept form
with slope m = 19
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
← slope of line w
Answer:
z * sigma+u = x
Step-by-step explanation:
z = (x-u)/ sigma
z is the z score, u is the mean, sigma is the standard deviation
We need to solve for x
Multiply each side by sigma
z * sigma = (x-u)/ sigma * sigma
z * sigma = x-u
Add u to each side
z * sigma+u = x-u+u
z * sigma+u = x
Answer:
-2a+b+5c
Step-by-step explanation:
Answer:
102
Step-by-step explanation:
Let the unknown measure be x
So all the angles add up to 180
therefore,
13 + 65 + x = 180
78 + x = 180
x = 180 - 78
x = 102
