Answer:
2(x-y) and 2x-2y are equivalent.
Step-by-step explanation:
To figure out 2(x-y) and 2x-2y, you can apply the distributive property on
to get:
Or we can factor
to get:
This implies that, the two expressions are equivalent.
The cost of labour per hour is $90.56
The total amount paid by Austin is the sum of the total cost of labour and the cost of the parts
Total amount paid = total cost of labour + cost of parts
$553.50 = total cost of labour + $126
total cost of labour = $533.50 - $126
= $407.50
The total cost of labour = cost of labour per hour x total time worked
$407.50 = xx × 4.5
xx = $407.50 / 4.5
xx = $90.56

Answer:
<h2>(-2, -4)</h2>
Step-by-step explanation:
Put the coordinates of the points to the equation, and check it:
(-4, -1) → x= -4, y = -1
L = -5(-4) - 3(-1) =20 + 3 = 23
R = 22
L ≠ R
(-1, -4) → x= -1, y = -4
L = -5(-1) - 3(-4) = 5 + 12 = 17
R = 22
L ≠ R
(-2, -4) → x= -2, y = -4
L = -5(-2) - 3(-4) = 10 + 12 = 22
R = 22
L = R CORRECT :)
(-4, -2) → x = -4, y = -2
L = -5(-4) - 3(-2) = 20 + 6 = 26
R = 22
L ≠ R
Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
