Answer: $\frac{4}{5}(7-6x)$

Step-by-step explanation:

We have the following expression:

$(1.3x+2.4)-(6.1x-3.2)$

Here we have to group similar terms, but firstly we have to solve what is inside the second parenthesis according to the rules of algebraic operations (equal signs give as a result a positive sing and different sings gives as a result a negative sing):

$1.3x+2.4-6.1x+3.2$

$5.6-4.8x$

This expression can be written as:

$\frac{28}{5}-\frac{24}{5}x$

Applying common factor $\frac{4}{5}$ :

$\frac{4}{5}(7-6x)$ This is the result

What is the range of f(x) = 3x + 9?

SOVA2 [1]

Step-by-step explanation:

there must be some additional information missing (like the domain of the function), because just as it is written here, the function f(x) would not have any limitations, and its range would be -infinity < y < +infinity.

so, it is impossible to tell you which answer option is correct.

because again, based on the given information, none of these options is correct.

Answer:

Plug in your variables value.

Step-by-step explanation:

For your case, plug in -6 into the y slot

12(5+2y)= -(6-9y) +4y

12(5+2x-6)= -(6-9x-6)+4y see if that works!
