Answer:
A candy costs $6.75 and a bag of popcorn costs $7.25
Step-by-step explanation:
Let the cost of one 1 candy=$x
Let the cost of one bag of popcorn=$y
Now, Total Cost Per Item=Number of Item Bought X Price Per Unit Item.
If Nathaniel bought 4 candies and 10 bags of popcorn for a total of 99.50 dollars.
4x+10y=99.50
Grant bought 3 candies and 5 bags of popcorn for a total of 56.50 dollars.
3x+5y=56.50
Solving the two equations simultaneously
4x+10y=99.50 (I)
3x+5y=56.50 (II)
Multiply Equation (I) by 3 and Equation (II) by 4 to eliminate x
12x+30y=298.5
12x+20y=226
Subtracting
10y=72.5
y=$7.25
Now, from (II)
3x+5y=56.50
3x+5(7.25)=56.50
3x+36.25=56.50
3x=20.25
x=20.25/3=$6.75
Therefore a candy costs $6.75 and a bag of popcorn costs $7.25

Answer:
x ∈ ℝ
Step-by-step explanation:
Since this is a constant function, this domain is the set of all real numbers.
Hope this helped! :)
That's 100 square units (her backyard) minus 16 square units (her pool) which equals 84 square units.
Rule A (x, y) → (x, -y) describes the transformation.
Step-by-step explanation:
Step 1; To understand reflection across an axis we need to be able to know which quadrant the shape is already in and in which quadrant it will be in after reflection. The given shape is currently in the fourth quadrant where the points in it will have a positive x coordinate and a negative y coordinate. So assume the values are in the format of (x, y).
Step 2; Due to reflection across the x-axis, the shape will be reflected in the first quadrant. In this, the x and y coordinates both have a positive value. So due to reflection, the x value remains unchanged while the y value is the same but it has the opposite symbol i.e. negative. So if the shape had a value of (x, y) due to reflection it would have (x, -y).
