Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34
False it is not it just said that if B is 100 then A is 35
Answer:
12+8=x or x-8=12 and they collected 20 leaves yesterday
Step-by-step explanation: Since they collected 8 fewer today, to find yesterday u would have to add. 12+8=20. PS idk if that makes sense srry
This is what the diagram is saying
(-4)+(-9)= -13
R(x) is a polynomial. Thus, the domain is the same as the range.
Domain = range = ALL REAL NUMBERS.
We can also express the answer as
(-infinity, infinity).
