BIG IDEAS MATH 4.4 Factor y3−5y2+6y−30 completely

Mathematics
1 answer:
azamat4 years ago
8 0

Answer:

  (y -5)(y -i√6)(y +i√6)

Step-by-step explanation:

The expression can be factored by grouping:

  (y^3 -5y^2) +(6y -30) = y^2(y -5) +6(y -5) = (y^2 +6)(y -5)

The quadratic factor is the difference of squares, if you consider -6 to be a square. In that view, it can be factored as ...

  y^2 +6 = (y -i√6)(y +i√6)

Then the complete factorization is ...

  (y -5)(y -i√6)(y +i√6)

Answer:

7³

Step-by-step explanation:

when dividing exponents that have the same base, you leave the base as the original (so in this case 7) and subtract the exponents (in this case it would be 9-6). that will be your new base and exponent.

In figuring his net income, Mr.Halkides listed his salary income of $15,000, $258 from his dividends,and $2562 from the sale of
Black_prince [1.1K]
Net income is all cost factors put together, so total income minus total expenses.

15000 + 258 + 2562 = 17820
1346 + 1598 + 48 = 2992
17820 - 2992 = $14828

f(n)=93+4(n-1)f(n)=93+4(n−1)f, left parenthesis, n, right parenthesis, equals, 93, plus, 4, left parenthesis, n, minus, 1, right
polet [3.4K]

Answer: f(n) = 4n + 97 (or 97 + 4n)

Step-by-step explanation:

Distribute 4 and (n-1)

f(n) = 93 + 4n - 4

Add 93 and 4

f(n) = 97 + 4n

Can u please help me with these three questions?? Please
V125BC [204]

Hello! What you're seeing in these images are two parallel lines cut by a transversal. There are many relationships between angles here.

----

Problem g: What you are seeing here is alternate interior angles - they are both on the inside of the lines, and are on opposite sides of the transversal. These angles are proven to always measure the same thing.

Therefore, 8x - 4 = 60. Use this equation, and solve.

8x - 4 = 60

8x = 64

x = 8

----

Problem h: Here, you are seeing corresponding angles. When you look at the two intersection points, these two angles are located "between the same sides". These angles are also proven to always measure the same.

Therefore, 6x = 5x + 10. Use this equation, and solve.

6x = 5x + 10

x = 10

----

Problem i: These are alternate exterior angels. These are located on opposite ends of the transversal, and are on the outside of the parallel lines. These angles also always measure the same.

Therefore, -1 + 14x = 12x + 17. Now solve.

-1 + 14x = 12x + 17

2x = 18

x = 9

----

Therefore, your three answers are x = 8, x = 10, and x = 9.

Hope this helps!
