She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.
the tax rate says 15% for the amount over 436
so fist find the amount that is taxable:
1149 - 436 = 713
now multiply that amount by 0.15 ( 15% as a decimal)
713 * 0.15 = 106.95
now add the base tax to that amount for the total amount of tax:
106.95 + 34.90 = 141.85 total tax withheld
Step-by-step explanation:
By Descrates' Rule of Signs,
x² + 99x + 127 changes sign 0 times.
Hence it has 0 positive roots.
Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.
Hence both the roots are negative. (B)
The domain is the scope of the x values. In this case (-2,-1) is a hole, so x>-2 is one end of the domain, while (3,3) is defined. So the domain using interval notation is (-2,3] which can also be expressed -2 < x ≤ 3, answer option 1
