Answer:

x=3/4,y=5/2

Step-by-step explanation:

y=-x^2+4,y=2x+1

substitute y=-x^2+4 as y for y=2x+1

2x+1=-x^2+4, x=3/4(isolate "x")

x=3/4

substitute x=3/4 for 2x+1=-x^2+4

y=2*3/4+1

y=5/2

x=3/4, y=5/2

hope this helps!

You work a part-time job at $7.85/hr for 10 hours per week. Your deductions are FICA (7.65%), federal tax withholding (9.8%), an

Dmitrij [34]

Here, My initial salary = 7.85

FICA deduction amount = 7.85 * 7.65% = 7.85 * 0.0765 = 0.60
Federal Tax amount = 7.85 * 9.8% = 7.85 * 0.098 = 0.77
State tax amount = 7.85 * 5.5% = 7.85 * 0.055 = 0.43

So, Total deducted amount = 0.60 + 0.77 + 0.43 = 1.80
Net hourly wage = 7.85 - 1.80 = 6.05

In short, Your Answer would be $6.05

Hope this helps!
