Ask questions in the comment section if you have questions. I'm happy to help! <3

Step-by-step explanation:

What the question is telling you is that x and y and proportional, almost like a ratio.

<h2>x : y</h2><h2>-3 : 6</h2>

Now we have to find y when x is four.

<h2>-3 : 6</h2><h3> to </h3><h2> 4 : y</h2><h2 />

Let's create a proportional equation...

<h3>(-3 / 6) = 4 / y</h3><h3>- 1 / 2 = 4 / y</h3>

What can we divide by four to create -1/2?

<h2>y = -8.</h2>

Answer:

y = -8

Step-by-step explanation:

6/-3 = -2

4 * -2 = -8

y = -8

Write the equation 2x-3y=6in slope -intercept form

Tcecarenko [31]

Answer:

y = 2/3 x -2

Step-by-step explanation:

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

We need to solve for y

2x-3y = 6

Subtract 2x from each side

2x-2x-3y=-2x+6

-3y = -2x+6

Divide by -3

-3y/-3 = -2/-3x+6 /-3

y = 2/3 x -2

The slope is 2/3 and the y intercept is -2

The graph of F(x) shown below resembles the graph of G(x) = x4, but it has

DerKrebs [107]

Using translation concepts, the equation of F(x) is:

A. $F(x) = \frac{1}{3}x^4 - 2$

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is:

$G(x) = x^4$

For function F(x), we have that:

It was shifted down 2 units, hence F(x) = G(x) - 2.

It was vertically compressed by a factor of 3, hence $F(x) = \frac{1}{3}G(x) - 2$

Then the equation is:

A. $F(x) = \frac{1}{3}x^4 - 2$

Brandon uses the steps below to solve the equation 15 x + 6 = 14 x + 5 using algebra tiles.

iris [78.8K]

Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2—— the answer would have been x=-1
