Answer:

x = 7

Step-by-step explanation:

3(x - 4) - 5 = x - 3

3x - 12 - 5 = x - 3

2x = -3 + 12 + 5

2x = 14

x = 7

VARVARA [1.3K]

Answer:

4x^4y + 20x^2y^2 - 28x^3y

Step-by-step explanation:

4xy(x^3 + 5xy - 7x^2)

= 4xyx^3 + 4xy * 5xy - 4xy * 7x^2

= 4x^2y + 4xy * 5xy - 4xy * 7x^2

= 4x^4y + 20x^2y^2 - 4xy * 7x^2

= 4x^4y + 20x^2y^2 - 28x^3y

X/9+3<4 what is the solution to the ineqaulity
11111nata11111 [884]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the solution to the inequality:

\star~\large\pmb{\cfrac{x}{9}+3 < 4}

\triangle~\fbox{\bf{KEY:}}

  • First, subtract 3 from both sides,  then multiply both sides by the denominator.

<u>Step 1.</u>

<u></u>

<u></u>\star~\large\pmb{\cfrac{x}{9} < 4-3}

\star~\large\pmb{\cfrac{x}{9} < 1}

<u>Step 2.</u>

<u></u>

<u></u>\star~\large\pmb{\cfrac{x}{9}\times9 < 1\times9}

Notice that on the left, the 9s cancel, and we're left with x.

<u>Step 3.</u>

<u></u>

<u></u>\star~\large\pmb{x < 9}

This is the solution.

Hope it helps you out! :D
