Ok, so you got the parent function y = x^2 and it changed to y = x^2 -8

#'s inside the parenthesis would move it left or right and #'s outside the parenthesis would move it up or down. Since there are no parenthesis the x coordinate is 0, hence it doesn't move left or right. Because of this we know that the graph will be moved up or down. Now we look to see is the # negative or positive. If negative, we move it down. If positive, we move it up. Looking at this problem, we see that it will move it down. Next look at the #. This will indicate how <em>much</em> you will move the graph. In this problem, we will move the graph down 8.

Therefore,

When you change the graph y = x^2 to y = x^2 -8, you are moving the graph down 8.

What is the solution to log Subscript 2 Baseline (9 x) minus log Subscript 2 Baseline 3 = 3

sdas [7]

The value of x is $\frac{8}{3}$

Explanation:

The expression is $\log _{2}(9 x)-\log _{2}(3)=3$

Adding $\log _{2}(3)$ to both sides of the equation, we get,

$\log _{2}(9 x)=3+\log _{2}(3)$

Using log definition, if $\log _{a}(b)=c$ then $b=a^{c}$ , we have,

$9 x=2^{3+\log _{2}(3)}$

Using exponent rule, $a^{b+c}=a^{b} a^{c}$ ,

$9x=2^{\log _{2}(3)} \cdot 2^{3}$

Simplifying, we have,

$9x=3\cdot8\\9x=24$

Dividing both sides by 9, we have,

$x=\frac{24}{9}$

Simplifying,

$x=\frac{8}{3}$

Thus, the value of x is $\frac{8}{3}$

PLS HURRY

ale4655 [162]

Answer:

this is the answer for (03.01 LC)

Step-by-step explanation:

You have use the Pythagorean Theorem a^{2} + b^{2} = c^{2}

So this is my work

$x^{5} + x^{5} = c^{2} \\25 + 25 = c^{2} \\50= c^{2} \\\sqrt{50} = \sqrt{c^{2} } \\\sqrt{50} = c\\$

extra notes

If you didn't know, you cancel exponents with roots.

So the c^{2} is cancled by aka \sqrt{c}

You can't simplify $\sqrt{50}$ so it stays like that

Answer: the answer for (03.06 LC)

Meow + meow = ? bark or moo

Dima020 [189]

Answer:

Moo

Step-by-step explanation:

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?

That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)
