Solve the equation for y.<br><br> 6y+x=8
iVinArrow [24]

Answer:

The correct answer is \bold{y = -\frac{1}{6}x+\frac{4}{3}}.

Step-by-step explanation:

We want to solve for y in the given equation. We can do this by rearranging the equation and using operational techniques to simplify.

6y + x = 8 \ $\tex Subtract x from both sides of the equation.

6y + x - x = 8 - x \ $\tex Carry out the operation.

6y = 8 - x \ $\tex Rearrange so the equation lists the variables first and the constants second.

6y = -x + 8 \ $\tex Create a coefficient for the x-variable (this is -1).

6y = -1x + 8 \ $\tex Divide by 6 on both sides of the equation in order to isolate the y-variable.

\frac{6y}{6}=\frac{-1x}{6} + \frac{8}{6} \ $\tex Carry out this operation by simplifying the fractions and dividing out the operations accordingly.

y = -\frac{1}{6}x+\frac{4}{3} \ $\tex Be sure to verify that all fractions and terms are simplified as far as they can be and that the equation is written in proper syntax.

Because we have the <em>y</em>-variable isolated from the rest of the equation, we are done!

Which of the following describes the transformation from Figure 1 to Figure 2?
Mrrafil [7]

9514 1404 393

Answer:

  Rotation 90° CCW

Step-by-step explanation:

Note that Figure 1 has a small appendage off the larger rectangle. That appendage is pointing East (to the right).

In Figure 2, that same appendage is pointing North (up).

If you are facing East and you want to face North, you will find that you need to turn 90° in the counterclockwise direction. That is the transformation that was done here:

  rotation 90° CCW about the origin

Sergio039 [100]

Answer:

  15 : 29

Step-by-step explanation:

  (3 3/4) / (7 1/4) = ((3·4+3)/4) / ((7·4+1)/4)

  = (15/4) / (29/4) = 15/29

The ratio of the two numbers is 15 : 29.
