show whether each equation has one solution, infinitely, many solutions or no solutions: 2x+7=-8x-9+10x​
alexira [117]

Answer:

  1. The statement is <em>false</em>
  2. There is<em> no solution</em>

Step-by-step explanation:

Step 1: <em>Collect the like terms</em>

2x+7 = -8x-9+10x

2x+7 = 2x-9

Step 2: <em>Cancel</em><em> </em><em>equal</em><em> </em><em>terms</em><em> </em><em>of</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em>

2x+7 = 2x-9

7 = -9

Result: The statement is <em>false</em> and there is <em>no solution</em> as 7 is <em>not equal</em> to -9.

I hope this helped ! ;)

Distribute -2x\left(-10x+1\right).−2x(−10x+1)
ZanzabumX [31]
<h3>I'll teach you how to distribute −2x(−10x+1)</h3>

----------------------------------------------------

−2x(−10x+1)

Apply the distributive law:

Ex. of distributive law:

a(b+c)= ab+ac

-2x(-10x)+(-2x)*1

Apply minus/plus rule:

2*10xx-2*1*x

Simplify 2*10xx-2*1*x:

2*10xx= 20x^2

2*1*x= 2x

20x^2-2x

Your Answer Is 20x^2-2x
