10 7/12. I think that's 127 I'm not sure
Answer:
-22
Step-by-step explanation:
f(x) = 5x -7
substitute x = -3 into the equation as follows:
f(-3) = 5( -3) -7
= -15-7
= -22
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
Wouldnt that be zero cuz they used more then they started of with?
