Which equation represents the polynomial function with zeros −1, 1, and 3 (multiplicity of 2), and a y-intercept of −18? (4 poin
Vlad [161]
Correct Answer:
3rd option is the correct answer

Solution:
The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:

y=a (x-3)^{2}(x-1)(x+1)

The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:

-18=a (0-3)^{2}(0-1)(0+1) \\  \\ 
-18=-9a \\  \\ 
a=2

The final equation of the polynomial becomes:

y=2 (x-3)^{2}(x-1)(x+1)

Find the solution to the system<br> of equations. Y=1/2x-1 and x=4
oksano4ka [1.4K]

the point where the two lines intersect will be your answer.

from the photo, your x-coordinate will be 4, and your y-coordinate will be 1. that's where the two lines meet, so that's the solution.

the answer will be (4,1).

i hope i helped! good luck.

Solve for x -(2x+5)+14=22
Gala2k [10]

Hey there!☺

Answer:\boxed{x=\frac{-13}{2}}

Explanation:

-(2x+5)+14=22 Equation

−(2x+5)+14=22  Simplify both sides

−2x + −5 + 14 = 22 Distribute

(−2x) + (−5+14) = 22 Combine Like Terms

-2x + 9 = 22

-2x + 9 - 9 = 22 - 9 Subtract 9 from both sides

-2x = 13

-2x/-2 = 13/-2

-13/2 Add the negative to 13

x = -13/2

Hope this helps!
