The graph below represents the linear equation y = one-half x minus 3. On a coordinate plane, a line goes through (0, negative 3
mamaluj [8]

Answer:

(C) (2, -2)

Step-by-step explanation:

Given the linear equation: y=\dfrac12x-3

A second linear equation is given by the table:

\left|\begin{array}{c|cccccc}x&-1&0&2&3\\y&1&0&-2&-3\end{array}\right|

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.

Therefore if:

y=\dfrac12x-3;$and $\\y=-x\\Then:\\\dfrac12x-3=-x\\\dfrac12x+x=3\\\dfrac32x=3\\3x=6\\x=2

Recall: y=-x

Therefore: y= -2

Therefore, a solution to the system of equations is (2, -2)

Q(x)=4x2-3x3+8x is it a cubic trinomial​
Norma-Jean [14]

Answer:

Yes

Answer:    x = 0

Step-by-step explanation:

Yes it is.

Down is the answer how to solve this equation and the steps.

Step  1  :

Equation at the end of step  1  :

 qx -  (((4 • (x2)) -  3x3) +  8x)  = 0  

Step  2  :

Equation at the end of step  2  :

 qx -  ((22x2 -  3x3) +  8x)  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  qx + 3x3 - 4x2 - 8x  =  

 x • (q + 3x2 - 4x - 8)  

Equation at the end of step  4  :

 x • (q + 3x2 - 4x - 8)  = 0  

Step  5  :

Theory - Roots of a product :

5.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

5.2      Solve  :    x = 0  

 Solution is  x = 0

Solving a Single Variable Equation :

5.3     Solve   q+3x2-4x-8  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Answer:  x = 0

Hope this helps.

How many words is 2-3 pages double spaced?
seropon [69]
It would be tricky to determine the number of words since there could be different usage of margins, font sizes and font styles.

However, based on an study by an institution, a 2-3 pages essay contains approximately 750 words in general.

The statement is true if you're going to use Arial 12, double spacing with 1 inch margin on a word document.
