The graph shows the height of a hiker above sea level. The hiker walks at a constant speed for the entire trip. What are the variables? Describe how the variables are related at various points on the graph.
A. The variables are height and time. For the first part of the graph, the height is increasing slowly, which means the hiker is climbing a steep incline. Flat parts of the graph show where the elevation does not change, which means the hiker stopped to rest. The steep part at the end of ...

Tom has a collection of 30 CDs and Nita has a collection of 18 CDs. Tom is adding 1 CD a month to his collection while Nita is adding 5 CDs a month to her collection. Find the number of months after which they will have the same number of CDs.
A. 1 month
B. 3 months
C. 2 months
D. 33 months

Weegy: equation to show work:
1x + 30 = ?
5x + 18 = ?
x = the number of moths
x = 3 User: What is the solution of the system?y = –3x + 2
y = –3x + 4 Weegy: 2(2x/3 + 7) - 3 = 5x 4x/3 + 14 - 3 = 5x 11 = 11x/3 x = 3 y = 2(3)/3 + 7 = 9 x(y) = 3(9) = 18. Answer is d. User: What is the solution of the system?y = x + 5
y = –5x – 1 Weegy: x=2 User: What is the solution of the system? Use substitution. y = x + 6 y = 2x
A. (6, 12)
B. (–12, –6)
C. (–6, –12)
D. (2, 4) Weegy: A. (6, 12). 12 = 6 + 6, 12 = 6 * 2. User: What is the solution of the system? Use substitution.
x = –2y + 10
–6y = 6x – 6
z = –3x + 10y
A. x = 9, y = –8, z = 114
B. x = –8, y = 9, z = 114
C. x = –8, y = 114, z = 9
D. x = 114, y = 9, z = –8 Weegy: A. x = 9, y = ?8, z = 114 is the answer. User: A corner store sells two kinds of baked goods: cakes and pies. A cake costs $5 and a pie costs $7. In one day, the store sold 15 baked goods for a total of $91. How many cakes did they sell?
A. 7 cakes
B. 4 cakes
C. 8 cakes
D. 5 cakes Weegy: A. 7 cakes User: How many solutions does the system have?
x = -4y + 4
2x + 8y = 8
A. one solution
B. two solutions
C. infinitely many solutions
D. no solution Weegy: B. two solutions User: What is the solution of the system? Use elimination. 3x – 4y = 9 –3x + 2y = 9
A. (3, 9)
B. (–27, –9)
C. (–3, –6)
D. (–9, –9) Weegy: 2(2x/3 + 7) - 3 = 5x 4x/3 + 14 - 3 = 5x 11 = 11x/3 x = 3 y = 2(3)/3 + 7 = 9 x(y) = 3(9) = 18. Answer is d. (More)

y = x + 5

y = –5x – 1

institute y in the second equation the result is:

x + 5 = -5x - 1

x + 5x = -1 - 5

6x = -6

x = -1

y = -1 + 5 = 4

The solution for the system y = x + 5 y = –5x – 1 is (-1, 4)

y = –5x – 1

institute y in the second equation the result is:

x + 5 = -5x - 1

x + 5x = -1 - 5

6x = -6

x = -1

y = -1 + 5 = 4

The solution for the system y = x + 5 y = –5x – 1 is (-1, 4)

3x – 4y = 9

–3x + 2y = 9

adding up equations the result is;

-2y = 18

y = -9

3x - 4(-9) = 9

3x + 36 = 9

3x = 9 - 36 = -27

x = -9

The solution for the system 3x – 4y = 9 –3x + 2y = 9 is (-9, -9)

–3x + 2y = 9

adding up equations the result is;

-2y = 18

y = -9

3x - 4(-9) = 9

3x + 36 = 9

3x = 9 - 36 = -27

x = -9

The solution for the system 3x – 4y = 9 –3x + 2y = 9 is (-9, -9)

Weegy: C. infinitely many solutions User: What is the solution of the system? Use substitution.
x = –2y + 10
–6y = 6x – 6
z = –3x + 10y
A. x = 9, y = –8, z = 114
B. x = –8, y = 9, z = 114
C. x = –8, y = 114, z = 9
D. x = 114, y = 9, z = –8 Weegy: A. x = 9, y = ?8, z = 114 is the answer. User: How many solutions does the system have?
