The sum of a number and 2 is 6 less than twice that number

IgorC [24]3 years ago

Step-by-step explanation:

The first thing we have to do before we can actually do the problem is turn the words into a math equation.

If we use <em>x </em>as our "number," we see that "The sum of a number and 2" can also be written as <em>x</em>+2. The word "Is" almost always means (=), so now we have (<em>x</em>+2) = . The very last part, "6 less than twice that number," means 2<em>x - </em>6.

So, our whole equation is, (<em>x </em>+ 2) = (2<em>x </em>- 6), which simplifies to -<em>x </em>= -8, or

<em>x</em> = 8

Answer:

y = 8

Step-by-step explanation:

number = y

y + 2 = 2y - 6

y + 2 - 2 = 2y - 6 - 2

y = 2y - 8

y - 2y = 2y - 2y - 8

- y = - 8

- y × - 1 = - 8 × - 1

y = 8

Identify the transformation of the function f(x)=|x| by observing the equation of the function g(x)=|x+3|
Alla [95]

Answer:

a horizontal translation by 3 units left

Step-by-step explanation:

f(x)= |x|

we are given with absolute function f(x)

g(x)  = |x+3|

To get g(x) from f(x) , 3 is added with x

If any number is added with x  then the graph of the function move to the left

Here 3 is added with x, so the graph of f(x) moves 3 units left to get g(x)

So there will be a horizontal translation by 3 units
