Determine whether y varies directly with x variation y=12x
zhenek [66]

y=12x is a direct proportion

Further explanation:

Let us define direct proportion.

"In direct proportion, one quantity varies directly with other quantity or the ratio between both quantities is always constant.

So,

Given:

y =12x

The general form of direct proportion is:

x=ky or y = kx

Here k is the constant of proportionality

Comparing the given variation with general form

y =12x

k = 12

So, the given variation is direct.

Keywords: Proportion, direct proportion

What is 5x-7(x+1)=9<br> Thanks for the help
mylen [45]

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

5x - 7(x + 1) = 9

Step 2: Solve for <em>x</em>

  1. Distribute -7: 5x - 7x - 7 = 9
  2. Combine like terms: -2x - 7 = 9
  3. Add 7 to both sides: -2x = 16
  4. Divide both sides by -2: x = -8

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

5(-8) - 7(-8 + 1) = 9

-40 - 7(-7) = 9

-40 + 49 = 9

9 = 9
