(18-7x)+1= -9 Hope this helps ^^
Answer:

Step-by-step explanation:
Let the equation of the perpendicular line is,
y = mx + b
where m = slope of the line
b = y-intercept
From the graph, slope of the line passing through (0, -1) and (3, 1),
m' =
m' = 
m' = 
To get the slope (m) of this line we will use the property of perpendicular lines,
m × m' = (-1)
m ×
= -1
m = 
Equation of the perpendicular line will be,

x-intercept of the line is (-3) therefore, point on the line is (-3, 0)
0 = 
b = 
Equation of the line will be,

The answer is B.
Since ΔQRS ~ ΔXYZ, the value of tan(Q) is :
- ∠Q = ∠X
- tan(Q) = tan(X)
- tan(X) = 3/4
- tan(Q) = 3/4
Danielle earned $951.25
Step-by-step explanation:
Multiply her commission by her sales and add her base rate
x=7.25%($4500)+625 or x=0.0725(4500)+625
distribute
x=326.25+625
simplify
x=951.25
