Answer:
y = 3x+3
Step-by-step explanation:
We know the y intercept since it crosses the y axis at (0,3) and we know the x intercept since it crosses the x axis at (-1,0)
We can fidn the slope
m = (y2-y1)/(x2-x1) (0,3) (-1,0)
=(0-3)/(-1-0)
= -3/-1
=3
The equation for the line is in the form
y = mx +b where m is the slope and b is the y intercept
y = 3x+3
The correct answer is x^3 - 5x^2 + 16x - 80.
In order to find this, we work backwards. Start by creating true statements for each of the roots.
x = 5
x = +/-4i
Now we can solve all of these until they are statements that equal 0.
x = 5 ----> Subtract 5 from both sides
x - 5 = 0
x = +/-4i ------> Square both sides
x^2 = -16 ---> Add 16 to both sides.
x^2 + 16 = 0
Now we can use the two statements that we have and multiply them to get the polynomial.
(x - 5)(x^2 + 16)
x^3 - 5x^2 + 16x - 80
The answer is B. If you write down the values of X and Y you’ll find out that the right answer is B.
