Solve the following inequality: –1 + 6(–1 – 3x) > –39 – 2x.
tino4ka555 [31]
<span>–1 + 6(–1 – 3x) > –39 – 2x.
Multiply the number outside of the parenthesis(6) by the numbers inside of the parenthesis(-1 and -3x)
-1 - 6 - 18x> -39 - 2x
Add 2x to both sides so that the x variable is only on one side
-1 - 6 - 16x> -39
Add 1 to both sides
-6 - 16x> -38
Add 6 to both sides
-16x> -32
Divide both sides by -16 so that the only thing that remains is the variable x on one side. Also, since you are dividing by a negative number, you automatically flip the greater than side to less than.
Final Answer: x< -2</span>

\large \mathfrak{Solution : }

Slope of the given line is :

  • \dfrac{y_2 - y_1}{x_2 - x_1}

where ,

  • x_2 = 1

  • x_1 =  - 3

  • y_2 =  - 7

  • y_1 =   - 4

let's solve :

  • \dfrac{ - 7 - ( - 4)}{1 - ( - 3)}

  • \dfrac{ - 3}{4}

Slope = -3 / 4

Let h(x)=2x−5 and g(x)=−3x+1.Find h(x)+g(x).? help please
Aleksandr-060686 [28]
This may look a little confusing but all you have to do is plug the equation given for h(x) which is 2x-5 in to the h(x) area in the equation where it says h(x) + g(x).

So far that’s (2x-5) + g(x)

Then,

Do the same with equation given for g(x) which is now,

(2x-5) + (3x+1)

Then solve,

2x - 5 + 3x + 1
2x + 3x- 5 + 1
5x - 4

Therefore the answer is 5x - 4.
