Answer:
<h2><u><em>
9/40</em></u></h2>
Step-by-step explanation:
Carol ate 2/5 of the cake; Dima ate 3/8 of the remaining cake, mom ate the rest. What fraction of the whole cake did mom eat?
1 - (2/5 + 3/8) =
1 - 31/40 =
9/40
-----------------
check
9/40 + 2/5 + 3/8 = 1
the answer is good
The slope is 3/2
Steps:
4 - (-2) = 6
5 - (-4) = 9
Put into a fraction, with the y sum on top.
Reduce
Answer: y=-x+7
Step-by-step explanation:
Answer:
Your given points: (9,-2)and (1,6)
x1=9
y1=-2
x2=1
y2=6
Step-by-step explanation:
To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1
6-(-2)/1-9=6+2/1-9=8/-8=-1
SLOPE IS m=-1
Then take that slope u got and plug into this equation to find equation of the line
y-y1=m(x-x1)
y-(-2)=-1(x-9)
y+2=-x+9
-2. -2

y=-x+7 ANSWER CHECK
Answer:(2,1/3)
Step-by-step explanation:
-x-3y=-3
2x+3y=5
_________First solve for x since y is 0. -3y+3y=0
1X = 2
1x/1= 2/1
X= 2
Now substitute your x answer into any equation to find y I used second equation
2x+3y= 5
2(2)+3y=5
4+3y=5
3y=5-4
3y=1
3y/3=1/3
Y=1/3
