Answer:

A) y - x = 6

B) y + x = -10   Let's add both equations:

2 y = -4

y = -2

From equation A) we see x is -8

The first answer is correct

Step-by-step explanation:

A candle is 9 inches long. Ronnie lights the candle and records the height of the candle, y inches, for x hours.​
DochEvi [55]

In the future, please post the full problem with all included instructions. After doing a quick internet search, I found your problem listed somewhere else. It mentions two parts (a) and (b)

Part (a) asked for the equation of the line in y = mx+b form

That would be y = -2x+9

This is because each time y goes down by 2, x goes up by 1. We have slope = rise/run = -2/1 = -2. This indicates that the height of the candle decreases by 2 inches per hour. The slope represents the rate of change.

The initial height of the candle is the y intercept b value. So we have m = -2 and b = 9 lead us from y = mx+b to y = -2x+9

----------------------------------------------------------------

Part (b) then asks you to graph the equation. Because this is a linear equation, it produces a straight line. We only need 2 points at minimum to graph any line. Let's plot (0,9) and (1,7) on the same xy grid. These two points are the first two rows of the table. Plot those two points and draw a straight line through them. The graph is below

Which of the following is a solution of x² + 14x + 112 = 0? If necessary, round to the nearest hundredth.

To determine the solution of the quadratic equation, use the quadratic formula which states that,
                                x = ((-b  +/- sqrt (b² - 4ac)) / 2a
From the equation, a = 1, b = 14, and c = 112. Substituting these to the quadratic formula,
                               x = <span>((-14  +/- sqrt (14² - 4(1)(12)) / 2(1) = indeterminate
Thus, the equation does not a real number solution. </span>

Explain how to find the product 3^5 x 3^2 using rules for exponents.
AlekseyPX

Step-by-step explanation:

\because \:  {a}^{m}  \times  {a}^{n}  =  {a}^{m + n}  \\  \\  \therefore \:  {3}^{5}  \times  {3}^{2}  =  {3}^{5 + 3}  =  {3}^{8}  = 6,561 \\
