Answer:
Step-by-step explanation:
Subtract 4 times the first equation from the second:
(-7y +16x -80) -4(-9y +4x -20) = (0) -4(0)
29y = 0 . . . . . simplify
y = 0 . . . . . . . .divide by 29
4x -20 = 0 . . . . substitute 0 for y in the first equation
x -5 = 0 . . . . . .divide by 4
x = 5 . . . . . . . . add 5
The solution to this system is (x, y) = (5, 0).
Answer:

Step-by-step explanation:
It can be divided into two equal halves.
Answer:
Step-by-step explanation:
In general, remember that the converse of is , therefore in this case
so
I think you typed the question wrong. It should be what is the population after seven DAYS.
The formula is
population = 30 * 1.8 ^ 7
and that equals d) 1837
X=1 2(1) = 2 - 3 = -1 11-5(1) = 6 nope
x=2 (2(2)=4 - 3=1 ( 11 - 5(2)=10 = 1) no
x>3 maybe.
