Answer:
d) ordered pairs are equal
e) ordered pairs are not equal
Step-by-step explanation:
d) ( 3+4 , 2 - 1)
x-co ordinate = 3 + 4= 7
y-co ordinate = 2 - 1 = 3
(3+ 4 , 2-1) = (7 , 3)
(3+4 , 2-1) & ( 7 ,3) are equal
f)Compare the x -co ordiante and y - co ordiante of the two pairs
p +q = q + p {addition closed under commutative property}
but q - p ≠ p - q {Subtract is not closed under commutative}
(p +q, q - p) & ( q + p , p -q ) are not equal
You put the highest exponent power first, then you go down until you reach a regular number (a number with a variable goes before a normal number)
Ex: 5x^3+2x^2+4x+5
Correct Answer: - 550
We can use the distributive property to distribute the summation to the variables and then get the constant out to apply the summation formulas as shown below in the attached image.
The equation editor does not have a summation symbol, so I have attached the solution using the image.
The correct answer to this question is -550. First option is the correct one.
Answer:
Gerrard
Step-by-step explanation:
Let the size of each poster be
Eve's poster portion painted will be
Gerrard's painted portion will be:
From the two inequalities, we find that is greater than by x/30
hence Gerrard has the larger blue section. His portion is 16.67% greater than Eve's
