Answer: -10, 10
Step-by-step explanation:
first lets add the two equations. add the x's, add the y's, add the constants on the right.
we get
0x - 1y = -10
so then divide --10 by -1 because we do the opposite operations to both sides
and we get y = 10
now substitute y = 10 into the first equation
-10x - 9(10) = 10
and then we get -10x - 90 = 10
now add 90 to both sides
-10x = 100
divide 100 by -10
x = -10
y = 10
checks out
EPIC. STAY EPIC AND AWESOME FRIEND.
You didn't include the graphs. However, I can describe the graph for you, so you can select the correct graph.
First, the car slows. So look for a line segment that is pointing down diagonally. Then, it maintains the speed. Look for a line that is horizontal. Finally, it slows down again to a stop. Look for a line segment that slants downward and touches the x axis.
The answer is 5 books.
m - the number of books sold on Monday
t - the number of books sold on Tuesday
w - the number of books sold on Wednesday
<span>On Tuesday, she sold twice as many books as she did on Monday: t = 2m
</span><span>On Wednesday, she sold 6 fewer books than she did on Tuesday: w = t - 6
</span><span>During the three days Rachel sold 19 books: m + t + w = 19
</span>t = 2m
w = t - 6 = 2m - 6
m + t + w = 19
______
Substitute t and w in the third equation:
m + 2m + 2m - 6 = 19
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25 : 5
m = 5
When 1 is divided into 8 pieces, each piece is 1/8 of the whole.
