The matching is given below.

  • Doubling          ⇒ 2
  • Quadrupling    ⇒ 4
  • Tripling            ⇒ 3
  • Halving            ⇒ 1/2

<h3>What is an exponent?</h3>

Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as

y = a(b)ˣ

You are asked to write exponential equations from word problems.

We know that factor 2 represents doubling, factor 4 represents quadrupling, factor 3 represents tripling, and factor 1/2 represents halving.

Then the matching is given below.

  • Doubling          ⇒ 2
  • Quadrupling    ⇒ 4
  • Tripling            ⇒ 3
  • Halving            ⇒ 1/2

If there is a wall that is nine feet tall and eleven feet wide, how many eight-by-ten inch picture frames can I put up? (Note: T
soldier1979 [14.2K]

The number of picture frames he can put on the wall is 178 picture frames.

The wall is rectangular and it is 9 feet tall and 11 feet wide.  let covert to inches.

9 feet = 108 inches

11 feet = 132 inches

<h3 /><h3>What is area:</h3>

The area is the space occupied by 2 dimensional figure. Let's find the area of the wall. Therefore,

area = lw

area = 108 × 132 = 14256  inches²

Therefore, let's find the area of the each picture frame. The frame is 8 inches by 10 inches.

area = 8 × 10 = 80 inches²

The number of picture you can put on the wall can be computed as follows:

  • 14256 / 80 = 178.2

He can put 178 pictures on the wall.

<u>Algebra I</u>

  • Terms/Coefficients
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -x + 1

2x + 3y = 6

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    2x + 3(-x + 1) = 6
  2. Distribute 3:                         2x - 3x + 3 = 6
  3. Combine like terms:           -x + 3 = 6
  4. Isolate <em>x</em> terms:                   -x = 3
  5. Isolate <em>x</em>:                              x = -3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                     y = -x + 1
  2. Substitute in <em>x</em>:                        y = -(-3) + 1
  3. Simplify:                                   y = 3 + 1
  4. Add:                                         y = 4
