2-(y + 2) = 3y Solve for y

Mathematics
1 answer:
alexgriva [62]3 years ago
3 0

Answer:

y=0

Step-by-step explanation:

Reorder the terms:

2 + -1(2 + y) = 3y

2 + (2 * -1 + y * -1) = 3y

2 + (-2 + -1y) = 3y

Combine like terms: 2 + -2 = 0

0 + -1y = 3y

-1y = 3y

Solving

-1y = 3y

Add '-3y' to each side of the equation.

-1y + -3y = 3y + -3y

Combine like terms: -1y + -3y = -4y

-4y = 3y + -3y

Combine like terms: 3y + -3y = 0

-4y = 0

Divide each side by '-4'.

y = 0

hope this helps

Which of the following describes the graph of y=\sqrt[3]{8x-64}-5 compared to the parent cube root function?
andriy [413]
Answer: stretched by a factor of 2 and translated 8 units right and 5 units down

Explanation:

These is the set of choices that accompany with this question:


<span>a) stretched by a factor of 2 and translated 64 units right and 5 units down
b) stretched by a factor of 8 and translated 8 units right and 5 units down
c) stretched by a factor of 2 and translated 8 units right and 5 units down
d) stretched by a factor of 8 and translated 64 units right and 5 units down


Solution:

</span>Let's work a little the given function to compare it with the parent function.

1) The given function is y = ∛[8x - 64] - 5

2) Extract common factor 8 of the expression inside the square brackets:

y = ∛[ 8( x - 8) ] - 5

3) Extract 8 from the root:

y = 2∛(x - 8) - 5

4) The parent function is ∛x. Call the parent function g(x) => g(x) = ∛x

5) Compare: y is 2 * g(x - 8) - 5

6) Analyze the meaning of that:

g(x - 8) means that the graph of the function is translated 8 units to the right

scaling by 2 means that the graph is stretch vertically (by a scale factor of 2)

- 5 means that the entire graph is shifted 5 units downward.

So, the description of the graph y = ∛(8x - 64) - 5 compared to the parent cube root function is: stretched by a factor of 2 and translated 8 units right and 5 units down
