Step-by-step explanation:
x+x squared =42. The square of the number is the number square. By my incredibly accurate guess and check strategy (works most of the time )6*6 = 36+6=42
The given statement is false because it isn't an empty set!
<u>Step-by-step explanation:</u>
We have following sets of inequalities:
![4x+5=13\\4x+5>13\\4x+5](https://tex.z-dn.net/?f=4x%2B5%3D13%5C%5C4x%2B5%3E13%5C%5C4x%2B5%3C13%5C%5C)
From
we get ,
![4x = 8 \\x=2](https://tex.z-dn.net/?f=4x%20%3D%208%20%5C%5Cx%3D2)
Therefore solution set is x=2.
Now, for
we get ,
![4x+5>13 \\4x>8\\x>2](https://tex.z-dn.net/?f=4x%2B5%3E13%20%5C%5C4x%3E8%5C%5Cx%3E2)
Therefore solution set is x>2.
For
we get ,
![4x+5](https://tex.z-dn.net/?f=4x%2B5%3C13%5C%5C4x%3C8%5C%5Cx%3C2%5C%5C)
Therefore solution set is x<2.
Now, the union of x=2, x<2 & x>2 is -∞<x<∞. i.e. all possible values of x. And so above statement is false because it isn't an empty set!
I think the answer is -20
Answer:
Yes, it is possible for Suri and Juan to make the same amount of wages if they both work 25 hours in one week.
Step-by-step explanation:
Let x = number of hours worked
Let y = total wages earned
Suri: 15x + 25 = y
Juan: 14x + 50 = y
Equate equations and solve for x:
15x + 25 = 14x + 50
Subtract 14x from both sides: x + 25 = 50
Subtract 25 from both sides: x = 25
Yes, it is possible for Suri and Juan to make the same amount of wages if they both work 25 hours in one week.
Original cost: $899.99
Markup (7%): 0.07($899.99)
Retail price = original cost plus markup = 1.07($899.99) = $962.99 (answer)
