Answer:
52-40
Step-by-step explanation:
distribute 4 to 13 and 10
put the subtraction sign back in
Answer:
See explanation
Step-by-step explanation:
A) the x-intercept is the solution because there are only x's in the equation when they are set equal to each other.
B) (-3, 8), (-3, 4)
(-2, 4), (-2, 4)***** this is the solution
(-1, 2), (-1, 4 1/8)
(0, 1), (0, 5)
(1, 1/2), (1, 12)
(2, 1/4), (2, 68)
(3, 1/8), (3, 516)
C) Graph them and show the intersection

Answer: 15
Step-by-step explanation: you basically add n per sequence.
0+1 = 1
1+2 = 3
3+3 = 6
6+4 = 10
10+5 = 15
Hope this helps
Answer:
D
Step-by-step explanation:
7 - z = 3 + z + 4 - 2z
7 - 3 - 4 = z - 2z + z
0 = 0 (Infinitely many solutions)
5(a + 4) - 15 = -5(a - 1)
5a + 20 - 15 = -5a + 5
5a + 5a = 5 - 20 + 15
10a = 40
10a/10 = 40
a = 4
(one solution)
-2d + 4d - 4 = 5 + 3(d - 3)
2d - 4 = 5 + 3d - 9
2d - 3d = 5 - 9 + 4
- d = 0
d = 0
(one solution)
-11(n - 2) + 8(n + 1) = -3(n + 10)
-11n + 22 + 8n + 8 = -3n - 30
-11n + 8n + 3n = -30 - 22 - 8
0 = -60
(no solutions)
