According to the synthetic division below, which of the following statements are true? Check all that apply.
-6)2 9 -12 2 -3 11

A. When x = -6,2x2 + 9x-7 = 11.
B. When x = 6,2x2 + 9x-7 = 11.
C. (x-6) is a factor of 2x + 9x- 7.
D. When (2x + 9x-7) is divided by (x - 6), the remainder is 11.
E. When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11. F. (x+6) is a factor of 2x2 + 9x-7.​

Answers

The last number on a synthetic division represents the remainder of the division.

The true statements are:

(a). When x = -6, 2x^2 + 9x - 7 = 11. (e). When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11.

From the question, we have the dividend to b 2x^2 + 9x - 7, the last number to be 11, and the zero of the divisor to be -6.

This means that:

[tex]x = -6[/tex] --- the divisor

Set to 0

[tex]x+6 = 0[/tex]

So, when the dividend 2x^2 + 9x - 7 is divided by divisor x + 6, the remainder is 11.

This also means that, when -6 is substituted for x in the dividend, the remainder is 11

Hence, the true statements are (a) and (e)

sketch the graph of the equation 3y+4x=2

Answers

Simplifying

3y + 4x = 2

Reorder the terms:

4x + 3y = 2

Solving

4x + 3y = 2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

4x + 3y + -3y = 2 + -3y

Combine like terms: 3y + -3y = 0

4x + 0 = 2 + -3y

4x = 2 + -3y

Divide each side by '4'.

x = 0.5 + -0.75y

Simplifying

x = 0.5 + -0.75y

The line connecting two coordinates (0,66)  and (0.5,0) show below.

What is Mathematical equation ?

By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.

Here, the given equation is :

3y + 4x = 2

now, to sketch the equation in graph we need to find the two coordinate first,

Let, x= 0 then y will be :

3y+4x=2

3y = 2

y = 2/3 = 0.66

that is first coordinate is (0,66)

Now, for y = 0 , x will be :

3y+4x=2

4x = 2

x = 0.5

that is second coordinate will be (0.5 , 0)

Now, draw the line connecting these two points show below.

[tex] \dfrac{16 - 11}{9 - 6} [/tex]

[tex] \dfrac{5}{3} [/tex]

slope of given line is 5/3

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :

[tex]y = mx + c[/tex]

[tex]11 = \bigg(\dfrac{5}{ 3} \times 6 \bigg) + c[/tex]

[tex]11 = (5 \times 2) + c[/tex]

[tex]11 = 10 + c[/tex]

[tex]c = 11 - 10[/tex]

[tex]c = 1[/tex]
