Answer:
false is the correct answer right
Answer:
y variable will be elimited when adding the system of equations
x = 2 or y = 3
Step-by-step explanation:
- x + 6y = 16
8x - 6y = -2
Add both equations
(-x + 8x) + {6y + (-6y)} = 16 + (-2)
7x + 6y - 6y = 16 - 2
7x + 0 = 14
7x = 14
x = 14/7
x = 2
- x + 6y = 16
- 2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
the x variable will be eliminating when adding the system of equations and the
y variable will be elimited when adding the system of equations
or the sum of the system equations is negative 8X = 14 or
x = 2 or y = 3
or there's only one solution to the system equations
Answer:
The 54th term is -855
Step-by-step explanation:
Since the sequence is arithmetic, then we have to use the rule of the nth term
a is the first term
d is the common difference
n is the position
The given sequence is -7, -23, -39
a=-7
d=-23-(-7)=-23+6=-16
We need to find the 54th term
n=54
Substitute them in the rule
Solve it:
The 54th term is -855
To solve for c :
3c=t+d
c=(t+d)/3
Answer:
18.84
Step-by-step explanation:
c=2×3.14(pi) × 6(diameter)/2
c=2×3.14×6/2
c=18.84
