-3+3n = -7+2n
-3+(3n-2n) = -7+(2n-2n)
since you subtracted 2n from both sides, 2n cancels out on the right side so you're left with
-3+n = -7
n = -7+3 = -4

Simplify the ratio 14/20
poizon [28]
To simplify a ratio, whatever you do to the bottom, you must do to the top. Find the GCF of both numbers, then divide until you can no longer simplify. I showed my work on a sheet of paper for a visual look.

What is the range of the function f(x) = 4 − 2(x + 3)^2?
mash [69]

Answer:

(-infinity, 4]

Step-by-step explanation:

The range is the possible y values

The smallest that (x+3)^2 can be is zero

f(x) = 4 − 2(x + 3)^2

f(x) = 4 -2(0) = 4

This is the maximum value

As the square term gets bigger we are subtracting a larger amount and it will get more negative

Let x = infinity, x+3 = infinity and infinity ^2 = infinity  and 2* infinity = infinity

f(x) = 4 - infinity

     = -infinity

The range is -infinity to 4
