Answer:
y = 5/4x - 18
Step-by-step explanation:
The slope, intercept form of a straight line is;
y = bx + c
Where, y = slope, given as 5/4
(x, y) is given as ; (8, - 8)
Hence, we need to obtain the value of c, which is the intercept.
x = 8 ; y = - 8
-8 = 5/4x + c
-8 = 5/4(8) + c
-8 = 10 + c
-8 - 10 = c
-18 = c
Hence, equation becomes ;
y = 5/4x - 18
Answer:
Step-by-step explanation:
The general formula for this sequence is a(n) = a(1)*(-1/4)^(n - 1). We don't yet know a(1).
If a(3) = 128, then 128 = a(1)*(-1/4)^(3 - 1), or
128 = a(1)*(1/16)
and so a(1) = 128/16
resulting in the specific formua a(n) = 8(-1/4)^(n - 1)
Now let's find a(7):
a(7) = 8(-1/4)^1 * (-1/4)^(6)
or
a(7) = 8(-1/4)^7
