Answer: identity (since the equation equal itself, there are infinity solutions)
9(x + 10) = 9(x) + 9(10)
9x + 90 = 9x + 90
Answer:
times
Step-by-step explanation:
Distance between Earth and the sun 
= 9 × 
miles = 
miles
Distance between Neptune and the sun 
= 3 × 
miles = 
miles
Find 
.
≈
Therefore,
Neptune is approximately times farther from the sun than earth
By looking at my notes, comparing and contrasting rational numbers that are integers to rational numbers that aren't is quite simple. Rational numbers are practically almost every single number in the number system. So...rational numbers that aren't integers would be fractions, decimals, and percentages. But rational numbers that are integers are whole numbers, either negative or positive. Hope this helps!
The estimated margin of error is 105, because that's the middle number and rounding to 2 it would still be 105.
The first thing you must remember is that the product of matrices is done by multiplying rows by columns.
For this case, the AB matrix is
AB = [1 0 0; 0 1 0; (x + 1) 0 y]
Equalizing the identity matrix we have
AB = I
[1 0 0; 0 1 0; (x + 1) 0 y] = [1 0 0; 0 1 0; 0 0 1]
Therefore we have
x + 1 = 0
y = 1
The values of x and y are
x = -1
y = 1
the answer is
X=-1
Y=1
