Answer: X=40
Step-by-step explanation:
Answer:
-3/2
Step-by-step explanation:
Given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (-7 - -1)/ (5-1)
= (-7+1)/(5-1)
= -6/4
= -3/2
Answer:
-11 x + 19 thus c.) is your answer
Step-by-step explanation:
Simplify the following:
-5 + 4 (6 - 2 x) - 3 x
4 (6 - 2 x) = 24 - 8 x:
-3 x + 24 - 8 x - 5
Add like terms. 24 - 5 = 19:
-3 x - 8 x + 19
-8 x - 3 x = -11 x:
Answer: -11 x + 19
Answer:
see explanation
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 )
Rearrange 2x + y = - 5 into this form by subtracting 2x from both sides
y = - 2x - 5 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 
, hence
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 1, - 2) into the partial equation
- 2 = - + c ⇒ c = - 
y = x - ← equation in slope- intercept form
