Answer:

Step-by-step explanation:
1. The initial equation given to us is
. Rearranging the equation to isolate
, we have:

2. Using the equation we rearranged in part 1, we can substitute given values:

3. We see from our equation in part 1 (
) that when
, the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.
Answer:
x=3,y=7
Step-by-step explanation:
8x+3y=45
2x+3y=27
8x-2x=6x
45-27=18
<u>6</u><u>x</u><u>=</u><u>1</u><u>8</u>
6. 6
x=3
2x+3y=27
2(3)+3y=27
6+3y=27
3y=27-6
<u>3</u><u>y</u> = <u>2</u><u>1</u>
3. 3
y=7
Answer:
-554 - 600 = -1154
the store's balance is $ -1154.00
Move the x's to the same side
2x + x = 8 +6
then simplify
3x = 14
make x stand on its own
(3x)/3 = 14/3
the 3's on the x side cancel
x = 14/3
