Five' more than twice a number is -13. Find the number

Mathematics

Paladinen [302]4 years ago

Answer:

<h2>-9</h2>

Step-by-step explanation:

n - a number

five more: + 5

twice a number: 2 · n = 2n

five more than twice a number: 2n + 5

The equation:

2n + 5 = -13           <em>subtract 5 from both sides</em>

2n + 5 - 5 = -13 - 5

2n = -18            <em>divide both sides by 2</em>

2n/2 = -18/2

n = -9

Translate Δ A B C 6 units horizontally. How are the values in the ordered pairs affected by the translation?
snow_tiger [21]

Answer:

The x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

Step-by-step explanation:

The given triangle has vertices at A(-4,1), B(-2,1) and C(-2,4)

The transformation rule for a horizontal translation by k units is

(x,y)\to (x\pm k,y)

In this case we have k=6

A(-4,1)\to A'(-4\pm6,1)

B(-2,1)\to B'(-2\pm6,1)

C(-2,4)\to C'(-2\pm6,4)

Therefore the x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

How would I find the surface area of the cone in terms of pi? It has a radius of 7 cm and a slant height of 19 cm.
julsineya [31]
The formula is SA = \pi r^{2} + \pi rl.  r is the radius and l is the slant height.  In your case it would be 49\pi + 133\pi = 172\pi.
