You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)

Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.

For which equation is x=0 NOT a solution?

Nimfa-mama [501]

B, is the only solution where x=0 isn’t the answer because 2.5x+3=x and if u subtract the 2.5x you get 3= -1.5x and if you divide 3 by -1.5 it won’t be x=0

What is -3/4 + 3/8? Thanks.

AURORKA [14]

Answer:

$- \frac{3}{8}$

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

$- \frac{3}{4} + \frac{3}{8} = - \frac{6}{8} + \frac{3}{8}$

Since the denominators are the same, we can add the numerators.

$\frac{ - 6 + 3}{8}$

$\frac{ - 3}{8}$

or it can be written as

$- \frac{3}{8}$

In the figure, side AB is given by the expression 5x+5x+3, and side BC is 3x+92x−4. The simplified expression for the area of re

miss Akunina [59]

Area = side AB * side BC = (5x + 5x + 3)(3x + 92x - 4)

= (10x + 3)(95x - 4) = 950x^2 - 40x + 285x - 12

= 950x^2 + 245x - 12 Answer

This cannot be negative so restriction on x is 950x^2 + 245x > 12
That is x > 0.0421
