4 0

Answer:

x = -2

Step-by-step explanation:

The coefficients of this quadratic are 1, 4 and 3.

                                                -b             -4

The axis of symmetry is x = --------- = ---------- = -2      =>       x = -2

                                                2(a)        2(1)

Answer:

  • l(x,y) = (-4y, -4x - 3)

Step-by-step explanation:

Let's start with function (x, y)

Transformations in the given order result in following

<u>A dilation by a factor of 4 with the origin as the center of dilation</u>

  • This results in both coordinates multiplied by 4
  • (x, y) → (4x, 4y)

<u>A reflection across the y-axis</u>

  • This results in x-coordinate changing sign to opposite
  • (4x, 4y) → (-4x, 4y)

<u>A 90° counterclockwise rotation about the origin</u>

  • This results in x-coordinate swapping with negative y-coordinate
  • (-4x, 4y) → (-4y, -4x)

<u>A translation 3 units down</u>

  • This results in y-coordinate change by -3
  • (-4y, -4x) → (-4y, 4x - 3)

<u>The final function is: </u>

  • l(x) = (-4y, -4x - 3)

Write a multiplication equation that has a solution of 12. Use tape diagrams to prove that your equation has a solution of 12.
natima [27]

Answer:

The required equation is 3y=36 and the tape diagram is shown below.

Step-by-step explanation:

Consider the provided information.

We need to write a multiplication equation that has a solution of 12.

3y=36

We know we have to split 36 into three equal groups, so we have to divide by 3 to show this algebraically.

3y÷3=36÷3

y=12

Now check this with the help of tape diagram as shown.

Consider the figure 1.

This represents if 36 had to be split into three groups, how big would each group be?

By the tape diagram we concluded that the value of y is 12.
