Since, the co-interior angles(55° and 125°) are supplementary(sum is 180), therefore the lines are parallel.
Answer:
4√2 and 5+4√2
Step-by-step explanation:
Let the two numbers be x ad y
Smaller = y
Bigger = x
If a positive real number is 5 more than another, then;
x = 5 + y ... 1
When - 10 times the smaller is added to the square of the larger, the result is 57, then;
-10y + x² = 57 ...2
Substitute 1 into 2;
-10y + (5+y)² = 57
-10y + 25+10y+y² = 57
y²+25 = 57
y² = 57 - 25
y² = 32
y = √32
y = 4√2
Since x = 5 + y
x = 5 + 4√2
Hence rhe numbers are 4√2 and 5+4√2
Let

be the number of rides Chandler takes in a month. Then the cost with the MetroCard is still $81, but the cost without the MetroCard is

. So we can set up an equation representing what we want: "The cost with a MetroCard of r rides in a month is less than the cost without a MetroCard." In equations,

Thus, at a minimum, Chandler must take 41 rides for his MetroCard to be cheaper than not having it.
A) Y U Z { B, C, D, F, G, H, K, T, L, M, N, W}
b) n(YUZ) {5} (<em>n</em> is the number of elements in the set)
c) X AND Y {K}
d) n(X AND Y) {16}
I'm not sure of that notation for e and f. Can you tell me what the X\Y means?
It looks like a 126%angle ok
