Here, we have to analyse the words and ages
The first statement is "Tom is younger than Andy" means Andy is older than Tom. So first comes Andy and then Tom. Let's Rank Andy =1 and Tom = 2 with 1 assigned to the older.
Now, the next statement is "John is not older than Tom" This means John is younger than Tom. This also means Tom is older than John. So John would become the youngest and hence we assign John = 3 (meaning the youngest)
Ordering from Youngest to oldest would be John (Rank 3), Tom (Rank 2) and Andy (Rank 1)
To conclude the order from youngest to oldest would be John,Tom,Andy
Step-by-step explanation:
Select all of the following that are quadratic equations.
x² + 3x - 5 = 0 ✓
x² - x = 3x + 7 ✓
5x - 7 = 0 X
7x² + 14x = 0 ✓
x³ - 3x² + 1 = 0 X
x - 5 = 9x + 7 X
What is quadratic equations?
Quadratic equations is a equation that has a general form like "ax² + bx = c"
For example :
x² + 3x - 5 = 0
x² + 3x = 5
x² → ax²
3x → bx
5 → c
Yes it is.
Step by step explanation:
Answer:
( original - new)/ original * 100 %
Step-by-step explanation:
Take the new amount
Subtract the original amount
( original - new)
Then divide by the original amount
( original - new)/ original
Multiply by 100% to get the percent loss
( original - new)/ original * 100 %
Answer:
Step-by-step explanation:
3y > 2x + 12
This inequality will be represented by the a dotted line and solution area for the inequality will be shaded area (In red) above the dotted line.
2x + y ≤ -5
y ≤ -2x - 5
This inequality will be represented by a solid line and solution area will be the shaded area (in blue) below the solid line.
Therefore, common area of both will be the solution area for the system of inequalities.
