Evan graphed a cubic function, f(x) = ax3 + bx2 + cx + d, and determined the roots of f(x) to be +1 and 2. What is the value of
Lana71 [14]

The value of b in the <em>cubic</em> polynomial is -4.

<h3>How to determine the coefficients of a cubic polynomial</h3>

After a quick analysis, we find that given <em>cubic</em> function is equivalent to the following equivalence:

x^{3}+b\cdot x^{2}+c\cdot x + d = (x-1)^{2}\cdot (x-2)

x^{3}+b\cdot x^{2}+c\cdot x + d = (x^{2}-2\cdot x + 1)\cdot (x-2)

x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-2\cdot x^{2}+x-2\cdot x^{2}+4\cdot x-2

x^{3}+b\cdot x^{2}+c\cdot x + d = x^{3}-4\cdot x^{2}+5\cdot x -2

After a quick observation, we conclude that the value of b in the <em>cubic</em> polynomial is -4. \blacksquare

I’m confused on this one
Mashutka [201]

Greetings!

The formula for the area of any triangle is as followed:

A_{triangle}=\frac{bh}{2}

-------------------------------------------------------------------------------------------------------------

<u>Let Statements:</u>

Let the variable...

→ b represent the length of the base of the triangle

→ h represent the length of the height of the triangle

-------------------------------------------------------------------------------------------------------------

Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

10=\frac{(4)(x+3)}{2}

Distribute the parenthesis<em> (The Distributive Property) </em>:

10=\frac{((4)(x)+(4)(3))}{2}

10=\frac{4x+12}{2}

Reduce the fraction to lowest terms:

10=2x+6

Add -6 to both sides of the equation:

(10)+(-6)=(2x+6)+(-6)

4=2x

Divide both sides of the equation by 2:

\frac{4}{2}=\frac{2x}{2}

2=x

-------------------------------------------------------------------------------------------------------------

The Answer to this Problem is:

\boxed{x=2}

-------------------------------------------------------------------------------------------------------------

I hope this helped!

Brainly use a matrix to find the solution to the system of equations -8x-8y=-16 6x-9y=-108
Mama L [17]
We want to use a matrix to solve
-8x - 8y = -16
6x - 9y = -108

Before solving, simplify the equations as follows:
Divide the first equation by -8 to obtain
x + y = 2             (1)
Divide the second equation by 3 to obtain
2x - 3y = -36       (2)

In matrix form, the equations are
\begin{bmatrix}1&1\\2&-3\end{bmatrix} \begin{\bmatrix} x\\y\end{bmatrix}=\begin{bmatrix}2 \\ -36 \end{bmatrix}

The determinant of the matrix is
D = (1)(-3) - (1)(2) = -5

Use Cramer's Rule.
x =  \frac{1}{D} det(\begin{bmatrix}2&1\\-36&-3 \end{bmatrix} ) =  \frac{1}{-5} (-6+36) = -6
Similalrly, 
y= \frac{1}{-5} det(\begin{bmatrix} 1&2\\2&-36\end{bmatrix} ) = \frac{1}{-5}(-36-4) =8

Answer:  (-6, 8)  or x = -6, y = 8

2/5 + 3/8 - Adding fractions
m_a_m_a [10]

Answer:31/40

Step-by-step explanation:

To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
