Answer:
Step-by-step explanation:
The following formula tells us that a quadratic equation can be solved:
which gives us the real and distinct roots
We have been given an equation:
Here, on comparing it with general quadractic equation which is:
Here, a=4,b=6 and c=2
On substituting the values in the formula to find D
Now, to find x:
we have a formula:
On substituting the values we get:
On simplification:
Answer:
$18
Step-by-step explanation:
Given:
y = 0.9x - 4.5
Where,
x = age in years
y = hourly pay in dollars
what is the best prediction for the hourly pay of a 25 year old?
That is, find y when x=25
y = 0.9x - 4.5
= 0.9(25) - 4.5
= 22.5 - 4.5
= 18
y = $18
The prediction for the hourly pay of a 25 year old is $18

3x+6= 4x+1 |Distributive
−x+6= 1 |SPOE (Subtraction Property of Equality)
−x= −5 |SPOE
x=5 |MPOE (Multiplication Property of Equality)</span>
the answer is 2/5

In order to find, Least common denominator for all of that fractions, you need to calculate the LCM of 8, 18, 9 , 14 ['cause they are denominators ]
It would be 494
So, Your Final Answer would be 494
Hope this helps!
