Answer: Yes, the set of real numbers is closed under addition.
Explanation:
Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.
There is no way to have x+y be nonreal while x,y are both real.
Slope is 0 and the y intercept is 3
If there is 20 stripes total, that means that the pattern can go through the a full cycle (2 green stripes, 3 blue stripes, and 1 yellow stripe) 3 times. Making that 3 blue stripes x 3 times through the cycle.
Which means 9 blue stripes.
Answer:
x = 9 and y = 13
Step-by-step explanation:
10x - 17 and 8x + 1 are Alternate Exterior angles so they equal the same.
So we are going make them equal each other.
10x - 17 = 8x + 1 ( plus 17 on both sides)
10x = 8x + 18 (subtract 8x on both sides)
2x = 18 (divide by 2)
x = 9
PLUG IN 8(9) + 1 = 73 so...
6y + 29 + 73 = 180 (two angle next to each other have to equal 180)
6y + 102 = 180 ( subtract 102 on both sides)
6y = 68 (divide by 6 on both sides)
y = 13
PLUG IN
6(13) + 29 = 107
