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>

100 x'
80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40
First find x: y= -2x+4 so you take that and substitute it into your second equation -x+3(-2x+4)=-9 ---> -7x+12=-9 ---> -7x= 3 ---> x=-3/7
Now you can find y by substituting x: y=-2x+4 ---> y=-2(-3/7) +4 ---> y=

Step-by-step explanation:
We have a graph given to us.
⇒ Take the points to form an equation!
<u>The points</u>
<u>Making an equation</u>
- Find the slope
- m = 1 - 6 / -2 - 4
- m = -5 / -6
- m = 5/6
- Take one of the two points and substitute in the equation :
- ⇒ y - y₁ = m (x - x₁)
- ⇒ y - 6 = 5/6 (x - 4)
- ⇒ y - 6 = 5x/6 - 10/3
- ⇒ <u>y = 5x/6 + 8/3</u>
- ⇒ or <u>6y = 5x + 16</u>
