Answer:
N=3
Step-by-step explanation:
27/9 = 3
Answer:
X=7 X=-1
Step-by-step explanation:
4(x^2 -6x -7) you saw that the common denominator was 4 so you divided everything by it.
(X-7)(X+1) Two numbers that multiplied give-7 and added -6 are those
X=7 X=1 equating those parenthesis to 0 gives you that
(6^-2 * 6^5)^-3
Raise each term by -3:
(6^-2)^-3 * (6^5)^-3 =
6^6 * 6^-15
Rewrite the second term using the negative exponent rule:
6^6 * 1/(6^15)
Subtract the exponents
15-6 = 9
The answer is 1 / 6^9 ( The second answer)
No false.
Remember the solution(s) to a system of equations is where the graphs all intersect if at all.
For the case of say a system of 2 lines, you can see the different possible outcomes..
-- If the two lines intersect at some point (x,y), that is one unique solution
-- If the two lines are parallel to each other, you see there are no intersection points and therefore this system of two parallel lines has no solutuion.
-- If the two lines overlap, really the same line written as a multiple of the other line, then you see they intersect at all points along the line, here there are infinite solutions.
