You would have to set the equation to the profit Jennifer got, which you know to be 63 dollars:
63=0.5e-5
To begin solving for e, which represents the number of erasers sold, add five to each side to get e alone.
68=0.5e
Multiply each side by two to get a whole x value on the right side
136=e
Jennifer sold 136 erasers
Answer:
75
Step-by-step explanation:
All of the angles within the triangle must add up to 180 degrees. So, angle 2 =50
The angles 4,2,5 also equal 180 because they are on the blue line. Since angle 2=50 and angle 5= 55 angle 4 must be 75 which is needed to add up to 180.
Answer:
The answer to your question is the first choice
Step-by-step explanation:
Data
Point = (-2, -5)
Process
Evaluate each of the equations on the point given.
A. y = x - 3
-5 = -2 - 3
-5 = -5 This is true so the point is on this line
B. y = 2x
-5 = 2(-2)
-5 = -4 The result is false so the point is not on this line
C. y = -3x
-5 = -3(-2)
-5 = 6 The result is false so the point is not on this line
D. y = x + 3
-5 = -2 + 3
-5 = 1 The result is false so the point is not on this line
Answer:
1.) slope is 6
2.) slope is -4
4.)slope is undefined
Step-by-step explanation:
1.) For one we can use the equation y2-y1/ x2-x1
First, pick any 2 points that you want to use to plug into the equation
(0, -3) and (1, 3)
Next, plug in and solve!
3-(-3)/ 1-0= 6
The slope is 6
2.) We can use this same equation for the problem and plug in!
(-1, 5) (2,-7)
-7- 5/ 2-(-1)= -4
The slope is -4!
4.) Use the same equation and find the slope!
(8, 1) and (8, 2)
2-1/ 8-8= undefined
Because we cannot divide by a 0 the slope is undefined!
The answer should be 10/45 which simplifies to 5/9. I hope this helps!
