Answer:
y = -1/2x + 2
Step-by-step explanation:
Answer:
For part a)
130 = 10/2[2a+(10-1)d]
Simplify, u get
2a + 9d = 26.................(1)
Also U5 = a + (5-1)d = 3a
Simplify, u get
a= 2d...................(2)
Substituting for a in equation 1,
2(2d)+9d= 26
Solving for d, we get
d = 2
In part b) substituting for d in equation 2 to get the first term
a = 2(2) = 4
Part c) the no. of terms required can be obtained by solving
28 = 4+(n-1)2
n = 13
(-4x + 42) = (64 - 6x)
-4x + 42 = 64 - 6x
+6x on both sides
2x + 42 = 64
-42 on both sides
2x = 22
/2 on both sides
x = 11
Answer:
x = 11
In standard form it would be 8,000,309
