Considering High School level question, answer can be written as:
A system of 2 linear equations is [two] dimensional. It is a graph of [two] lines. The solutions can be [unique] solution if the graph intersects. [No] solution if the lines are parallel - meaning they have the same slope, or [Infinitely many] solutions if they are the same line.
Explanation:
when two lines are drawn on a two-dimensional plane then there are only three possible cases:
Case1: lines will intersect
In that case you will get a unique solution at the intersection point.
Case2: lines are parallel but don't touch each other
In that case there will be no point which lies on both lines so No solution.
Case3: lines are overlapping.
In that case all the points lies on both lines so infinitely many solutions.
Answer:
C) 8 ft
Step-by-step explanation:
you use the pythagorean theorem to find the height.
a² + b² = c²
a = radius
b = height
c = slant height
15² + h² = 17²
h = 8
Solution :
P(2 states or more | college degree)
![$=\frac{\text{P( 2 states or more and college degree)}}{\text{P(college degree)}}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B%5Ctext%7BP%28%202%20states%20or%20more%20and%20college%20degree%29%7D%7D%7B%5Ctext%7BP%28college%20degree%29%7D%7D%24)
Total number of people = 58
The number of people who lived in two states or more than two states and also have a college degree = 18
Therefore,
![$\text{P(2 states or more states and college degree)} = \frac{18}{58}$](https://tex.z-dn.net/?f=%24%5Ctext%7BP%282%20states%20or%20more%20states%20and%20college%20degree%29%7D%20%3D%20%5Cfrac%7B18%7D%7B58%7D%24)
The number of people who have a college degree = 20
So, ![$\text{P(college degree)} = \frac{20}{58}$](https://tex.z-dn.net/?f=%24%5Ctext%7BP%28college%20degree%29%7D%20%3D%20%5Cfrac%7B20%7D%7B58%7D%24)
Thus,
![$\text{P(2 states or more/college degree)}=\frac{\frac{18}{58}}{\frac{20}{58}}$](https://tex.z-dn.net/?f=%24%5Ctext%7BP%282%20states%20or%20more%2Fcollege%20degree%29%7D%3D%5Cfrac%7B%5Cfrac%7B18%7D%7B58%7D%7D%7B%5Cfrac%7B20%7D%7B58%7D%7D%24)
![$=\frac{18}{20}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B18%7D%7B20%7D%24)
= 0.900
Answer:
D
Add all of the sides together. 2x+1 plus 2x+1 equalls 4x +2
Then add that to (xsquared+3x-2 + xsquared+3x-2) which is 2xsquared +6x-4+4x+2 which equalls D
