Answer:
6 < x < 8
Step-by-step explanation:
The compound inequality in this instance represent the "and" condition, not the "or" condition.* We might solve it like this.
-47 > 1 -8x > -63 . . . . given
Multiply by -1:
47 < -1 +8x < 63
Add 1:
48 < 8x < 64
Divide by 8:
6 < x < 8
______
* You can tell this is the case by looking at the ends of the given statement:
-47 > -63 . . . . a true statement, so the solution set will be an intersection, not a union.
Answer:
C. hyperbola; 
Step-by-step explanation:
The given conic has equation:
Divide through by 225.
This is a hyperbola centered at the origin.
The hyperbola has been translated from the origin to (0,5).
The translated hyperbola will have equation;
Multiply through by 225.
Expand
Rewrite in general form;
Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
