Answer:

A) x = 5.4, x = -1

Step-by-step explanation:

Equations:<em> f(x) = x² - x - 12, g(x) = 3.4x - 6.6</em>

If f(x) = g(x)

Substitute: <em>x² - x - 12 = 3.4x - 6.6</em>

Subtract: x² - 4.4x - 5.4 = 0

Two numbers w/ sum of -4.4x and product of -5.4x²: -5.4x and 1x

Substitute: x² - 5.4x + x - 5.4 = 0

Factor: (x - 5.4)(x + 1) = 0

Solve: x = 5.4, x = -1

2(4x -4) + 8x = 2 (8x -3) solve for x please
Brrunno [24]

Answer:

No Solutions

Step-by-step explanation:

Let's solve your equation step-by-step.

2(4x−4)+8x=2(8x−3)

Step 1: Simplify both sides of the equation.

2(4x−4)+8x=2(8x−3)

(2)(4x)+(2)(−4)+8x=(2)(8x)+(2)(−3)(Distribute)

8x+−8+8x=16x+−6

(8x+8x)+(−8)=16x−6(Combine Like Terms)

16x+−8=16x−6

16x−8=16x−6

Step 2: Subtract 16x from both sides.

16x−8−16x=16x−6−16x

−8=−6

Step 3: Add 8 to both sides.

−8+8=−6+8

0=2

Answer:

There are no solutions.

What is the sum of the arithmetic series below? Use the formula for the sum of an arithmetic series.
Papessa [141]
To determine the sum of the arithmetic series, simply remember that i is the pattern that you are going by which is 1,2,3.

The top value on the sigma sign tells you the final value that you must go to.

So use the equation to go from 1 to 18. So it would be 2(1) + 9 + 2(2) + 9 etc.
