Lindsay is playing a video game. She begins with an initial score of
500 points but loses 280 point throughout the game. She represents
her score using the expression shown.
500 - 280
Which of the following expressions also represents Lindsay's video
game score?
O A. 280 - 500
O B. 280 + 500
O C. 500 - (-280)
O D. 500 + (-280)
The expressions also represent Lindsay's video game score is 500 + (-280). The correct option is D.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Lindsay is playing a video game. She begins with an initial score of 500 points but loses 280 points throughout the game.
The expression will be written as below:-
E = 500 + (-280)
Therefore, the expressions also represent Lindsay's video game score is 500 + (-280). The correct option is D.

Use inverse operations to find the inverse of y = 27x?
The inverse of y = 27x3 is y =
Answer:
y = (∛x)/3
Step-by-step explanation:
To undo the multiplication by 27, you multiply by its inverse:
(1/27)y = (1/27)(27x^3)
y/27 = x^3 . . . . . . . . . . . simplify
To undo the cube, you take the cube root:
(∛y)/(∛27) = ∛(x^3)
(∛y)/3 = x
Apparently, you want the inverse function, so you swap the variables:
y = (∛x)/3
_____
You can swap the variables at the beginning or end. It doesn't matter. If you do it at the beginning, you have ...
x = 27y^3
and you're solving for y. You use the same inverse operations that we used above.

AB formed by (-8, -1) and (-4, 2)
CD formed by (0, -3) and (12, 6)
The lines AB and CD are parallel lines.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The slope of line AB is m=2+1/-4+8
m=3/4
The slope of line CD is m=9/12=3/4
Both the lines AB and CD having the same slopes.
In parallel lines the slope will be same.
Hence, the lines AB and CD are parallel lines.

In a family of 4 children under 10 years old, the sum of the square of the ages of the 3 youngest is equal to the square of the age of the oldest. How old are these children
Answer: 2, 3, 6 and 7.
Step-by-step explanation:
We have four natural numbers A, B, C and D.
such that all of these numbers are smaller than 10, and:
A < B < C < D.
A, B and C are the ages of the smaller ones, and D is the age of the larger kid.
Now we have the relation
A^2 + B^2 + C^2 = D^2
We can write this as:
D = √(A^2 + B^2 + C^2)
And remember that D must be smaller than 10, then now we can play with the numbers A, B and C in order to find D.
Suppose for example:
A = 1, B = 2, C = 3
D = √( 1^2 + 2^2 + 3^2) = √(1 + 4 + 9) = √14
This is not a whole number.
Then we have that A^2 + B^2 + C^2 must be a perfect square.
The perfect squares we can aim for are:
4*4 = 16
5*5 = 25
6*6 = 36
7*7 = 49
8*8 = 64
9*9 = 81
now, looking at that comes to my mind to try to reach the 49.
because we can take the 36, add 4 to that (4 = 2*2) and then add 9 (9 = 3*3)
A^2 + B^2 + C^2 = 49
where we can use:
A = 2. B = 3 and C = 6
2^2 + 3^2 + 6^2 = 4 + 9 + 36 = 49
Then we have:
D = √(2^2 + 3^2 + 6^2 ) = √49 = 7
Then the ages of the children (for smallest to largest) are:
2, 3, 6 and 7.

russell bought a CD player that costs $120 before it went on sale for 15% discount. If he paid 5% sales tax on the sale price, how much did russell pay for the cd player?
Answer:
$107.10
Step-by-step explanation:
The original price of the CD player is $120 and we need to take 15% off.
We can find how much we need to subtract by multiplying 120 by .15, which equals 18. Then we can subtract that from 120, to get a sales price of $102.
A shortcut is subtracting 15 from 100 to get 85, and then doing 120*.85 = 102.
From the sales price of 102, there's a 5% tax to add on. 102 * .05 = 5.1
102+5.1 = 107.1
Answer:
$107.10
Step-by-step explanation:
First, find the discount.
Multiply the discount rate, 15% by the price of the CD player, $120
discount rate * price
15% * $120
Convert 15% to a decimal. Divide 15 by 100 or move the decimal place two spots to the left.
15/100= 0.15 or 15.0 --> 1.5 --> 0.15
0.15 * $120
$18
Since it is a discount, subtract $18 from the regular price of $120.
$120-$18
$102
Next, find the tax.
Multiply the tax rate, 5% by the price of the discounted CD player, $102
tax rate * discounted price
5% * $102
Convert 5% to a decimal. Divide 5by 100 or move the decimal place two spots to the left.
5/100= 0.05 or 5.0 --> 0.5 --> 0.05
0.05* $102
$5.10
Since it is tax, add $5.10 to the discounted price of $102.
$102 + $5.10
$107.10
Russell will pay $107.10 for the CD Player after a discount and tax.

3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x
