Area of a square quilt = 289 square inches
Area of a smaller square quilt = 121 square inches
Area of a square = a²
Side length of big square quilt = √289 in² = 17 inches
side length of small square quilt = √121 in² = 11 inches
Perimeter of big square = 17 inches * 4 = 68 inches
perimeter of small square = 11 inches * 4 = 44 inches
difference = 68 inches - 44 inches = 24 inches.
Y = 7.50x.....y = earnings per week , x = number of packages delivered
48 packages.....so x = 48
y = 7.50(48)
y = 360.....so if he delivers 48 packages, he earns $ 360
Hello there!
We are given the function:
To find the range, we know that domain is the set of all x-values and also called 'input' while range is the set of all y-values and also called 'output'.
Basic Function - you add the input, you get the output. You add x-value in a function, you get y-value. You add domain, you get range.
So, we substitute x = 1,2 and 3 in the function.
<u>x</u><u> </u><u>=</u><u> </u><u>1</u>
Recall that any numbers in absolute value are always positive.
<u>x</u><u> </u><u>=</u><u> </u><u>2</u>
<u>x</u><u> </u><u>=</u><u> </u><u>3</u>
Therefore, Range: {-1,1,3}
Let me know if you have any questions!
