(x - 4)(x - 4)=0. Then, (x - 4)=0 and (x - 4) =0.

In both cases, x is 4. Thus, you have a double real root: {4, 4}.

Answer:

7

Step-by-step explanation:

x - 4 =  

16 - x

(x - 4)2 = 16 - x

x2 - 8x + 16 = 16 - x

-x2 + 7x = 0

-(x(x - 7)) = 0

multiple both sides by -1:

x(x - 7) = 0

x = 0 or x = 7

Check solutions:

x = 7 ⇒

7 - 4 =  

16 - 7

3 =  

9

3 = 3

x = 7 is a solution

x = 0 ⇒

0 - 4 =  

16 - 0

-4 =  

16

-4 ≠ 4

x = 0 is not a solution (extraneous root)

V / -0.8 +14=39 plssss help this is literally so hard ​
Nat2105 [25]
<h2><u>Answer:</u></h2><h2> \boxed{\boxed{\sf~v=-20}}</h2><h2 /><h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) Subtract 14 from both sides:</h3>
  • 14-14= Cancels Out
  • 39-14=25

<em>  - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>

<u>Equation at the end of Step 1: </u>

  • v ÷ -0.8=25

<h3>2.) Multiply both sides by −0.8:</h3>
  • -0.8 × -0.8= Cancels Out
  • 25 × -0.8=-20

Lonzell said the function shown in the graph is positive on the interval (−,) and negative on the interval (−,−)open negative 5
Nezavi [6.7K]

Answer:

The positive graph is on the points  (-5,-4) and (2,5)

And, negative would be (-4,2)

Step-by-step explanation:

As it seems that fgraph shows positive in the case when it is over x-axis, and negative when it is below y-axis

As on the interval (-1,5)

The graph is below x-axis i.e. on (-1,2)

And, over x-axis i.e. on (2,5)

At this point Lonzell’s  is not correct

As on the interval (-5,-1)

The graph is below x-axis i.e. on (-4,-1)

And, over x-axis i.e. on (-5,4)

 At this point Lonzell’s  is not correct

So,

The positive graph is on the points  (-5,-4) and (2,5)

And, negative would be (-4,2)
