So you want to add 18500+9%=20,165 and then divide 20165 by 48 and you get 420.10
Rosa earned $50
Explanation:
Two people Rosa & her brother
Her brother earns X
While Rosa earns 2X + 8
Now we gotta solve for X
They made $71. $71 minus X should give you Rosa’s pay
71 - X = 8 + 2X (subtract 8 from 71)
63 - X = 2X (add X to 2X)
63 = 3X (divide by 3)
21 = X
Plug in $21 for Rosa:
8 + 2(21)
8 + 42 = $50
Answer- vertical;congruent
The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
