Answer:
The answer is 3.
Step-by-step explanation:
Since you do the parentheses first, you will figure out what why is. Y = 3, because 3*3 =9, and 9-9=0.
Answer:
Step-by-step explanation:
A is a subset of B while B is the universal set.
AB = A U B
A is a subset of B. That is A is contained in B.
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =1
m the slope m= -1 (same slope for the line : x+y=9 because this lines are parallel and you can write y=-x+9
an equation for this line is : y-1 = -(x-5)
Answer: 3
Explanation:
27 = 3^3
42 = 2 x 3 x 7
So the HCF of (27,42) = 3
