Answer:
10
Step-by-step explanation:
Follow PEMDAS
5 (2+1) x 2 divided by 3
calculate within parenthesis
(2+1) : 3
5 x 3 x 2 divided by 3
multiply and divide (left to right)
= 10
* x = times sign
<u>Given</u>:
The given equation is 
We need to determine the exact solutions of the equation.
<u>Exact solution:</u>
The exact solution of the equation can be determined by solving the equation using quadratic formula,

From the equation the values are a = 1, b = -3 and c = -7
Thus, substituting these values in the equation, we get;



Thus, the exact solutions of the given equation is 
Hence, Option A is the correct answer.
Answer:
1: Reflect M across the x-axis
2: Dilate about the center by 3/2
Step-by-step explanation:
Given
See attachment for M and N
Required
Which maps M to N
The coordinates of the radius of the circles are:


And the radius of circles are:


The first transformation from M to M' is:
- Reflect across the x-axis
The rule is:


<em>At this point, M' and N now have the same center but different radius.</em>
The second transformation from M' to N is:
- Dilate about the center by dividing the radius of N by the radius of M
i.e.


<em>At this point, M has been completely mapped to N.</em>
