Answer:
15
Step-by-step explanation:
we are given
![-2x(x+1)=-2x+5](https://tex.z-dn.net/?f=-2x%28x%2B1%29%3D-2x%2B5)
Since, we have to solve for x
so, we will isolate all terms on left side
step-1:
Distribute -2x
![-2x\times x-2x\times 1=-2x+5](https://tex.z-dn.net/?f=-2x%5Ctimes%20x-2x%5Ctimes%201%3D-2x%2B5)
![-2x^2-2x=-2x+5](https://tex.z-dn.net/?f=-2x%5E2-2x%3D-2x%2B5)
step-2:
Add both sides by 2x
![-2x^2-2x+2x=-2x+5+2x](https://tex.z-dn.net/?f=-2x%5E2-2x%2B2x%3D-2x%2B5%2B2x)
![-2x^2=5](https://tex.z-dn.net/?f=-2x%5E2%3D5)
Step-3:
Divide both sides by -2
and we get
![x^2=-\frac{5}{2}](https://tex.z-dn.net/?f=x%5E2%3D-%5Cfrac%7B5%7D%7B2%7D)
now, we can take sqrt both sides
![\sqrt{x^2} =\sqrt{-\frac{5}{2}}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%7D%20%3D%5Csqrt%7B-%5Cfrac%7B5%7D%7B2%7D%7D)
we get

Question: The sample data and the scatter plot was not added to your question. See the attached file for the scatter plot.
Answer: Yes
Step-by-step explanation:
From scatter plot, it was discovered that there is a linear relationship between the two variables and both variables are quantitative.
Therefore, it appropriate to use the correlation coefficient to describe the strength of the relationship between "Time" and "Fish Quality"?
Answer:
Cost of Pizza for 1 inch radius is $0.5.
The Direct variation between cost of pizza and radius in inches of pizza is ![C= 0.5r](https://tex.z-dn.net/?f=C%3D%200.5r)
Step-by-step explanation:
Given:
Cost of 6 inch pizza = $3.00
We need to find the direct variation equation to represent cost of pizza with a 1 inch radius.
Let Cost f Pizza be represented by 'C'.
Also radius in inches of pizza be represented by 'r'.
First we will find Cost of pizza for 1 inch radius.
Now 6 inch pizza = $3.00
So 1 inch Pizza = Cost of pizza for 1 inch radius.
By Using Unitary method we get;
Cost of pizza for 1 inch radius = ![\frac{3}{6} = \$0.5](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B6%7D%20%3D%20%5C%240.5)
Cost of Pizza for 1 inch radius is $0.5.
Hence We can say the direct variation would be given as;
![C= 0.5r](https://tex.z-dn.net/?f=C%3D%200.5r)
Hence The Direct variation between cost of pizza and radius in inches of pizza is ![C= 0.5r](https://tex.z-dn.net/?f=C%3D%200.5r)
