Answer:
x < -3
Step-by-step explanation:
The domain in which the function is increasing or getting bigger is from x is negative infinity to is -3
x < -3
Answer:
The percentage increase in worker wages in hourly rate of pay is 16.5%
Step-by-step explanation:
Given as :
The Initial wages earn by worker = $ 5.15 per hour
The Final wages earn by worker = $ 6 per hour
Let The percentage increase in her hourly rate of pay = x %
Now, According to question
x % = 
or, x =
× 100
or, x =
× 100
or, x = 0.165 × 100
∴ x = 16.5%
So , Percentage increase in wages = x = 16.5 %
Hence The percentage increase in worker wages in hourly rate of pay is 16.5% Answer
Answer:
x = 3 or -3
Step-by-step explanation:
So you have the equation x² - 9 = 0
Move the 9 to the other side: x² = 9
Then take the square root of both sides:
= ±
x = ±
= ±3
x = 3 or -3
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem. Why not "give it the old college try?"
Start by choosing letters to represent the unit cost of each popcorn and drink:
p: popcorn, d: drink.
Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".
Solve this system of linear equations simultaneously:
2p + 3d = $22.25
12p+4d=$39.00
In your shoes I would mult. the first equation by -6 and then combine the result with the second equation. p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.
