<span>Solutions or Roots of Quadratic Equations. A real number x will be called a solution or a root if it satisfies the equation, meaning . It is easy to see that the roots
are exactly the x-intercepts of the quadratic function , that is the
intersection between the graph of the quadratic function with the
x-axis.</span>
Answer:
The total monthly cost would be $214
explanation:
They gave us 1,250, which is half of 2,500. multiplication:
1,250 = 2,500
107 = x
2 × 1,250 = 2,500
2 × 107 = 214
Therefore, the total monthly cost if the cell phone is used for 2,500 minutes is $214.
I dont know how to delete a answer and i got it wrong apparently so sorry
The first one shows 1 cm and 7 mm, we need to convert 7 mm to cm
1 cm + 7 mm
= 1 cm +

cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cmThe second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches.
The second one is 11
inches.The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm
