For this case we must algebraically rewrite the given expression. So:

x: It is the variable that represents an unknown number

"double a number" is represented as: 2x

"6 less than double a number" is represented as: 2x-6

So, the final expression is: 2x-6

If we want to rewrite the expression in an equivalent way, we take common factor 2:

2 (x-3)

Asnwer:

2x-6

Equivalent expression: 2 (x-3)

Answer:

x,y ⇒x+10, y+10

Step-by-step explanation:

from looking at the graphs we can see there is only horizontal and vertical translations

take any point, for example the point C and it's transformed counterpart C'

and determine the change in x and y position

the point is translated 10 right and 10 up

so from x,y ⇒x+10, y+10

In the graph shown, which ordered pair does NOT represent a solution to the graph?
andreyandreev [35.5K]
A) (1, 7) Doesn't
B) (0, 4) Doesn't
C) (2, –2) Doesn't
D) (3, –5) DOES

All the steps are right at the exception of line 7 (and onwards)

line 6 : 6x = 42 (it's right). Now divide both sides by 6:

line 7 should be:  6x/6 = 42/6
line 8 should be: x = 7.

jasenka [17]

Answer:

$1,379.17

Step-by-step explanation:

Here A = ($1,300)(1 + 0.03)^2

            = ($1,300)(1.03)^2  =  $1,379.17
