Answer:

5/-3

Step-by-step explanation:

The slope formula is rise/run.

If you graph this, the two points make a line that slopes downwards. The higher point is in the negative axis, which means that the run will be negative.

you rise up 15 points from the first point (1,-6) to get to the same level as the second point. (-8,9). This is your rise.

You go over to the other point, this is your run. The run is -9.

15/-9

we can simplify  this fraction.

5/-3 is your final answer.

USPshnik [31]

Answer:

12\dfrac 12\%

Step by step explanation:

\text{Let it be}~ x\%,\\\\~~~~~72 \cdot x \% = 9\\\\\\\implies 72\cdot \dfrac{x}{100} = 9\\\\\\\implies x = \dfrac{9 \times 100}{72}\\\\\\\implies x = \dfrac{100}{8}\\\\\\\implies x = \dfrac{25}2\\\\\\\implies x = 12 \dfrac 12\\\\\\\text{Hence 9 is}~ 12\dfrac 12\% ~ \text{of}~ 72

Brandon has a box 9.5 inches tall, 3.8 inches wide, and 4.2 inches long. How many square inches of wrapping paper does he need t
olya-2409 [2.1K]

Answer:

183.92 inch²

Step-by-step explanation:

To find the total amount of wrapping paper needed, you must find the Surface Area of the box.

Surface area of a rectangular prism is: A = 2(<em>wl</em> + <em>hl</em> + <em>hw</em>)

w = width = 3.8

h = height = 9.5

l = length = 4.2

Plug in the corresponding numbers to the corresponding variables.

A = 2(<em>wl</em> + <em>hl </em>+ <em>hw</em>)

A = 2((3.8 * 4.2) + (9.5 * 4.2) + (9.5 * 3.8))

Simplify.

A = 2((15.96) + (39.9) + (36.1))

A = 2(15.96 + 39.9 + 36.1)

A = 2(91.96)

Multiply.

A = 183.92

183.92 inch² is your answer.

Fiesta28 [93]

Answer: 2014

Step-by-step explanation:

LED: -25x + 6y = 20

CFL: 15x + 2y = 322

we need to find which year it was the same to know where LED lighting surpassed  CFL lighting

-25x + 6y = 20

15x + 2y = 322 (-3)

-25x + 6y = 20

<u>-45x - 6y = -966     </u>

-70x = -946

x = 13.51

The nearest year would be 14 which is 2014
