Find the value of this expression if x=9 x2 + 6 / x - 6
GREYUIT [131]

Answer:

87/3

Step-by-step explanation:

Here we are given the expression:

\frac{x^{2}+6}{x-6}

Now we have to find the value of this expression when x equals 9.

So plugging the value of x as -9 in the given expression:

\frac{x^{2}+6}{x-6}

=\frac{(9)^{2}+6}{9-6}

=87/3

So on evaluating we get the value of expression as 87/3.

Solve the equation<br> (x-3)^3-( x - 1 )^3 + 7x^2 = 7(3x - 4 )
Yakvenalex [24]

Answer:

x= -1 or x = -2

Step-by-step explanation:

Your equation:

(x−3)^3−(x−1)^3+7x^2=7(3x−4)

Step 1: Simplify both sides of the equation.

x^2+24x−26=21x−28

Step 2: Subtract 21x-28 from both sides.

x^2+24x−26−(21x−28)=21x−28−(21x−28)

x^2+3x+2=0

Step 3: Factor left side of equation.

(x+1)(x+2)=0

Step 4: Set factors equal to zero.

x+1=0 or x+2=0

which equals to x=−1 or x=−2

Which equation represents a line which is parallel to the line 8y-3x=-8
marin [14]

First, we need to make the equation given to be in the form;

y=mx + b

where m is the slope and b is the intercept

8y - 3x = -8

Add 2x to both-side of the equation

8y = 3x - 8

Divide through the equation by 8

y = 3/8 x -1

comparing the above with y =mx + b

m = 3/8

slope of parallel equations are equal

From the options given the only equation with slope 3/8 is;

y= 3/8 x + 8

y=\frac{3}{8}x\text{ + 8}

The above equation of the line is parallel to 8y - 3x = -8
