Given a 1 =4,r=-5, n=7 what its the value of a(7)

-29

Step-by-step explanation:

If and r = -5 for the rate or difference between terms, then the sequence is 1, -4, -9, .... etc.

To find a(7), continue the pattern until you find the 7th term.

1, -4, -9, -14, -19, -24, -29....

a(7) = -29

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the translated point is (5,2)
