Which statement is true about the function f(x)= StartRoot negative x EndRoot?

sveticcg [70]

Because x is negative the domain of the function is all negative real numbers.

Set the radical greater than or equal to 0:

-x >= 0

Turn x positive by multiplying both sides by -1. When you multiply an inequality by -1 you need to reverse the inequality sign:

X <= 0

Domain is all real numbers below 0 so all negative real numbers.

If she saves 1$ the first week 3$ the season week 9$ the third week how much will she save in 5 weeks

ycow [4]

Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).

Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.

Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.

Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks

Customers who purchase museum tickets in advance receive 10% off the regular admission price. Anias paid a sale price of $54. He

alisha [4.7K]

Answer:

Regular price of a ticket = $60

Step-by-step explanation:

Given:

On purchasing museum tickets in advance customers get 10% off on the regular price of ticket.

Anias paid the sale price of ticket = $54

To find the regular price of ticket.

Solution:

Let the regular price of ticket in dollars be $=x$

Discount offered for booking in advance = 10%

Discount amount in dollars = $Discount\ percent \times Regular\ price=10% \times x =0.10 \times x =0.1x$

Sale price of a ticket in dollars= Regular price - Discount amount= $x-0.1x=0.9x$

Sale price given for a ticket = $54

So, we have:

$0.9x=54$

Dividing both sides by 0.9

$\frac{0.9x}{0.9}=\frac{54}{0.9}$

∴ $x=60$

∴ Regular price of a ticket = $60
