Answer: (1,1)
Step-by-step explanation:
5x-y=6
-1(5x+2y=3)
5x-y=6
-5x-2y=-3
-y=6
-2y=-3
-3y=-3
y=1
5x-(1)=6
5x=5
x=5
Answer:
<em>xr</em> ≤ 7
Step-by-step explanation:
He must spend less than or equal to 7$ to account for 5 trips and 3 extra dollars for 1 trip.
Yes! All of them. Good job! They all form words!
x^2 - 4
------------------------------
x + 7 | x^3 + 7x^2 - 4x - 28
x^3 + 7x^2
------------------
0 - 4x - 28
-4x - 28
-------------
0
Now we know that
x^3 + 7x^2 - 4x - 28 = (x^2 - 4)(x + 7)
x^2 - 4 can be factored since it is the difference of two squares.
x^2 - 4 = (x + 2)(x - 2)
The complete factoring is:
x^3 + 7x^2 - 4x - 28 = (x +2)(x - 2)(x + 7)
