Answer: 2

Step-by-step explanation:

    −y + 25 = 12y − 1

Переместите все члены, содержащие y, в левую часть уравнения

Вычтем 12y из обеих частей уравнения.

    −y + 25 − 12y = −1

 Вычтем 12y из −y.

    −13y + 25 = −1

Переместите все члены, не содержащие y, в правую часть уравнения.

Вычтем 25 из обеих частей уравнения.

    −13y = −1 − 25

Вычтем 25 из −1.

    −13y = −26

Разделите каждый член на −13 и упростите.

Разделите каждый член в −13y = −26 на −13.

     −13y /-13 = -26/-13

Сократить общий множитель −13.

    −26 /-13

Разделим −26 на −13.

    y = 2

The length of a rectangular box is 4 times its width, and its height is 7in more than its width. The volume of the box is 126in3
Ierofanga [76]

Answer:

  1.88 inches

Step-by-step explanation:

The volume is the product of length, width, and height. If w represents the width of the box, then its length is 4w and its height is w+7. The volume is then ...

  V = (4w)(w)(w+7)

We want to find the value of w that makes V=126. It is convenient to use the graphing calculator to look for zeros of a function, so we can write the equation as ...

  V - 126 = 0

  4w·w·(w+7) -126 = 0

The only positive solution to this equation is near w ≈ 1.883.

The width of the box is about 1.88 inches.

Attached is output from the DESMOS free graphing calculator. The ALEKS calculator requires a subscription. The method of solution is substantially the same, but requires a little more work on the ALEKS calculator to find the zero-crossing.
