HELP PLSSS I NEED THIS ASAP
Kamila [148]

Multiplying the linear expressions, the correct sequence is given as follows:

  • 5x(-3 -7x)
  • (5x)(-3) + (5x)(-7x)
  • -15x - 35x²

<h3>How are linear expressions multiplied?</h3>

They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.

Hence:

5x(-3 -7x)

(5x)(-3) + (5x)(-7x)

-15x - 35x²

Hence the last option is correct.

Solve using Elimination<br><br> 3x+y=-9<br> y=5x+7
valentinak56 [21]

Answer

x=-2 and y=-3

Step-by-step explanation:

Step: Solvey=5x+7for y:

Step: Substitute5x+7 for y in 3x+y=−9:

3x+y=−9

3x+5x+7=−9

8x+7=−9(Simplify both sides of the equation)

8x+7+−7=−9+−7(Add -7 to both sides)

8x=−16

8x/8=−16/8

(Divide both sides by 8)

x=−2

Step: Substitute−2 for x in y=5x+7:

y=5x+7

y=(5)(−2)+7

y=−3(Simplify both sides of the equation)

If UW =9x-9 what is UW as units
Vaselesa [24]
UW is always equal to 9x-9 or 9(x-1) whenever x is a real number.  By adding in x, we can get the value.
 
For example, if x was 4, we add in x, giving us 9*4-9=36-9=27 units or
9(4-1)=9(3)=27 units

Hoped this helped in time!
