Answer:
2n-3
Step-by-step explanation:
n represents the number of hours Darcy practices.
The number of hours Hannah practices each week is 3 hours less than twice the number of hours Darcy practices.
Twice the number of hours Darcy practices is 2n.
Hannah practices for : 2n-3
Hence, the expression that represents the number of hours Hannah practices is "2n-3".

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19

Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)

Gemma earns $575 a week plus $180 commission for each car she sells. She earned
$1835 last week. How many cars did she sell?
O She sold 6 cars.
O She sold 7 cars.
O She sold 8 cars.
O She sold 9 cars.
Answer:
7 cars
Step-by-step explanation:
Gemma earns $575 a week plus $180 in commission for each car sold
She earned $1835 last week
Therefore the amount of cars sold can be calculated as follows
= $575 + $180(7)
= $575 + $1260
= $1835
Hence 7 cars were sold

A company's profits for a week are as follows:
Monday: +$32.65, Tuesday: -$75.32,
Wednesday: -$125.75, Thursday: +$100.89,
and Friday: +$65.30. Does the company show
a gain or loss at the end of the week?
Answer:
Loss
Step-by-step explanation:
If you add all the numbers up you get -2.23 which would be a loss
Answer:
The company shows loss
Step-by-step explanation:
32.65 - 75.32= -42.67 so they're already at a loss
you would add -125.75 and -42.67 and woud get -168.42
Then you would add 100.89 and 65.30 and you would get 166.19
166.19+(-168.42)=-2.23

The options satisfying expressions that result to zero are,
A. - 52 + 52.
E. - 83 - ( - 83).
What are additive and multiplicative inverses?A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
A number added to it's additive inverse results to zero.
From the given options the only options that satisfies the result to be zero
are,
- 52 + 52.
- 83 - (- 83).
= - 83 + 83.
As the negative signs distribute to make it a positive number.
