Answer:
The 71st term is 428.
Step-by-step explanation:
Use Arithmetic Explicit formula:
f(n) = f(1) + (n - 1) d
Solve:
f(71) = 8 + (71 - 1) 6
f(71) = 8 + (70) 6
f(71) = 8 + 420
f(71) = 428
Answer:
hope this helps
Step-by-step explanation:
9+6(10-7x)
=9+60-42x
=69-42x
4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12
Since you know what y is, you can plug the value into the second equation
6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3
Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0
Solution: x = 3, y = 0
Answer:
x=-4
Step-by-step explanation:
The two lines are parallel, so the two angles, 45 and x+49 are equal too
Lets make the equation
x+49 = 45
x = 45-49
x = -4
