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)

Step-by-step explanation:
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.
