Answer:
Mathematics can be completed through the use of logical thinking and the use of equations to figure out various problems.
<h3>
Explanation:</h3>
For a system of 2 equations in 2 unknowns, there are 3 cases:
- slopes are different — one solution
- slopes are the same and y-intercepts are different — no solutions
- slopes and y-intercepts are the same — infinitely many solutions
When slopes are different, the two lines intersect at <em>one</em> point, the <em>solution</em>.
When slopes are the same, the lines may be either parallel (different y-intercepts) or the same (same y-intercepts). If the lines are parallel, there are no points of intersection, hence <em>no solutions</em>. If the lines are the same line, they intersect at all points, so there are <em>infinitely many solutions</em>.
Answer:
They are called exponents, they multiply the number itself (the bigger number) so the answer to 10 with a little 2, means 10x10 or "100"
Answer:
∠ C = 44°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
4x - 16 +6x - 1 + 4x - 13 = 180°
14x - 30 = 180 ( add 30 to both sides )
14x = 210 ( divide both sides by 14 )
x = 15
Thus
∠ C = 4x - 16 = 4(15) - 16 = 60 - 16 = 44°
