Answer is -7
=============================================
Work Shown:
s_n = a_1*(1-r^n)/(1-r)
s_6 = a_1*(1-r^6)/(1-r)
s_6 = x*(1-(-3)^6)/(1-(-3))
s_6 = x*(1-729)/(1+3)
s_6 = x*(-728)/4
s_6 = x*(-182)
s_6 = -182x
-182x = s_6
-182x = 1274
x = 1274/(-182)
x = -7 is the first term of the geometric sequence
------------
Extra info:
The first six terms of this geometric sequence is
-7, 21, -63, 189, -567, 1701
those six terms add to
-7+21+(-63)+189+(-567)+1701 = 1274
which verifies we have the right answer.
It’s 45, as the equation for a parallelogram is A= bxh, and 9x5 is 45
Answer:
$85,837.41
Step-by-step explanation:
The future value will be ...
P(1 +r)^t
$20,000(1 +.06)^25 ≈ $85,837.41
100 because sum means addition so 1+0+0 is one, and one X one hundred is 100
Hope this helps :D
Answer:
y = 3x + 23
Step-by-step explanation:
Given the equation :
y - 8 = 3(x + 5)
We are to convert the equation to slope - intercept form:
Recall: general form of a slope - intercept model:
y = mx + c
Hence,
y - 8 = 3x + 15
y = 3x + 15 + 8
y = 3x + 23
Comparing :
y = mx + c
y = 3x + 23
