Answer:
make a graphical representation for our case do we have infinite lines pass through a point M?
Step-by-step explanation:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
Answer:
3 • (2x - 7) - (x + 4) = 0
then do 3.1 Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) = 0
4.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5

Answer:
Expression I and IV
Step-by-step explanation:
Expression I simplified :
- 3n + 7 + n + 4n
- 8n + 7
- Expression I = Expression IV
Answer:
Step-by-step explanation:
<u>Count the number of letters</u>
- 1 = one ⇒ 3 letters
- 2 = two ⇒ 3 letters
- 3 = three ⇒ 5 letters
- 4 = four ⇒ 4 letters
- 5 = five ⇒ 4 letters
- 6 = six ⇒ 3 letters
Remember that the formula for the circumference, 
, of a circle is:
In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,
,
and we can say the circumference of our circle is:
The circumference of our circle is 50.24 units.
<em>Also, a little side note not relating to the question:</em>
<em>Remember that 
is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.</em>
