Sammie's monthly take-home pay is $3600, and his monthly rent is $900. If both his monthly take-home pay and his rent increase b
2 answers:
The original salary = $ 3,600
The increased salary will be = $ 3,600 + $ 250 = $ 3,850
The original rent = $ 900
The increased rent will be = $ 900 + $ 250
Since, both rent and salary increased by $ 250.
Now, the percentage of Sammie' salary paid as rent will be calculated as -
Percentage of salary paid as rent = × 100
Percentage of salary paid as rent = × 100
<u>Percentage of salary paid as rent = 29.9%</u>

Answer:
- there are 4 complex solutions
- 3 real zeros and 2 complex zeros
Step-by-step explanation:
1. Descarte's rule of signs tells you there are 0 positive real roots and 0 or 2 negative real roots. (for positive x, signs are ++++ so have no changes; for negative x, signs are ++-+, so have 2 changes.) A graph shows no real roots.
2. There are 3 sign changes in the given polynomial, so 3 or 1 positive real roots. When the sign of x is changed, there are 2 sign changes, so 0 or 2 negative real roots. A graph shows 2 negative and one positive real root (for a total of 3), so the remaining 2 roots are complex.
