8=2x(divide both sides by 2
x=4(now replace the X with 4
DP=3x+2=3(4)+2
=12+2=14
PE+5x-6=5(4)-6

Given the function f(x) = -5x + 11 + 3, for what values of x is f(x) = -12?<br> Bleaseeeeee
Nitella [24]

Answer:

x = 5.2

Step-by-step explanation:

f(x) = -5x + 11 + 3

Let's first simplify our first function:

f(x) = -5x + 11 + 3\\f(x) = -5x + 14

Now, we just need to set this function equal to our other given function.

f(x) = -5x+14\\f(x) = -12\\-5x + 14 = -12

Now, we can add 12 to both sides:

-5x + 14 + 12 = -12 + 12\\-5x + 26 = 0

Now, add 5x to both sides:

-5x+26 = 0\\26 = 5x\\

Finally, we'll divide both sides by 5:

26/5 = 5x / 5\\5.2 = x\\x = 5.2

Answer: x = 5.2
