Answer:
9 1/3
Step-by-step explanation:
As you may know, when you divide a positive number by a negative number, the quotient (result of the division) is negative.
Knowing this, all you have to do is divide the numbers normally as positive numbers and then add a negative sign at the end.
To divide fractions, you change the sign to multiplication and multiply the first number by the reciprocal of the second number.
The reciprocal is just the "flipped" version of a fraction.
For example, the reciprocal of 3/4 would be 4/3.
In this problem, you can't reduce.
So, just multiply the top numbers and do the same with the bottom numbers.
That would be 
.
35*4=140 and 5*3=15.
The fraction would be 140/15
You can divide 140 by 15, which would be 9 and 1/3
Answer:
90° rotational symmetry about the poiy(-1,0)
When x=5, f(g(x)) would be (x-1/4)^2 - 3(x-1/4) + 3 which when you plug 5 in for x, you get 11.3125 as an answer

Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = 9 → (1)
x + 2y = 1 → (2)
Rearrange (2) expressing x in terms of y by subtracting 2y from both sides
x = 1 - 2y → (3)
Substitute x = 1 - 2y into (1)
2(1 - 2y) - 3y = 9
2 - 4y - 3y = 9
- 7y + 2 = 9 ( subtract 2 from both sides )
- 7y = 7 ( divide both sides by - 7 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 1 - 2(- 1) = 1 + 2 = 3
solution is (3, - 1 )
