Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s
100 = 2s + 50
50 = 2s
25 = s
you need to make at least 25 sales
Answer:
d=4.5

Answer:
D
x >= -8
multiply by 2
-X <= 8
divide by -1
X >=-8 (remember flip sign if multiply by negative)
Step-by-step explanation:
y = -
x + 
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 4x + 5 is in this form with slope m - 4
Given the slope of a line m, then the slope (
) of a line perpendicular to it is
= - (1 / m ) = - 
y = -
x + c is the partial equation of the perpendicular line
to find c, substitute ( 2, 7 ) into the partial equation
7 = -
+ c ⇒ c = 
y = -
x +
← equation of perp. line
