Answer:
x=-3, y=-6. (-3, -6).
Step-by-step explanation:
-4x+y=6
-5x-y=21
--------------
-9x=27
x=27/-9
x=-3
-5(-3)-y=21
15-y=21
y=15-21
y=-6
In order a0->a5: 1/3, 1, 3, 9, 27, 81
All you're doing is plugging the x-value in. So for a2, x=1, so y=3¹ which means y=3.
Answer:
238
Step-by-step explanation:
299+428-62-106-126-195
727-62-106-126-195
665-106-126-195
559-126-195
433-195
238
The given equation is
First we solve for y, and for that, we have to islolate y, that is
And it pass the vertical line test. So here y is a function of x .
So we can define the given equation as y as a function of x .
Answer:
The Magazines each costed $8.30 and the books cost $13.80 for the amount of $41.50. and the 2 magazines and 5 books for $42.25 the 2 magazines is $21.12 for each and $8.45 for each book.
