The property of equality
Sauron [17]3 years ago
5 0

For this case we have the following equation:

m + 6 = -4

For properties of equality, we have to:

When the same value is added or subtracted on both sides of an equation, then equality remains the same.

Therefore, by applying this property, we subtract 6 from both sides of the equation:

m + 6-6 = -4-6\\m + 0 = -4-6\\m = -10

Answer:

The property of equality that is used is:

Add or subtract a number on both sides of the equation.

Josh invested $12,000 in mutual funds and received a sum of $20,000 at the end of the investment period. Calculate the ROI.
tresset_1 [31]

Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

              = 20,000-12,000

              =8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

      = 66.67%

Hence the return on investment is 66.67%!

3. If the sum of (3+6i) and (4+pi) is (7+81), then what is the value of p?
Aliun [14]

Answer:

p=2

Step-by-step explanation:

(3+6i) and (4+pi) is (7+8i)

3+4 = 7

6i+pi = 8i

Subtract 6i from each side

pi = 8i-6i

pi = 2i

That means p = 2

Which graph represents the piecewise-defined function? y={−45x−3   if  x<03x−10   if  x≥2
Nikitich [7]

Step-by-step explanation:

y=\left \Bigg\{ {\big{-45x-3 \qquad x < 0} \atop \big{3x - 10 \qquad x \geq2 }} \right.

\begin {array}{c|c}{ x&y}}\\ -\infty&-\infty\\-2&-93\\-1&-48\\ 0 &-3^*\\1&nothing\\2&-4\\3&-1\\4&2\\ \infty&\infty\\\end{array}

* open dot

You did not provide the graphs to choose from so use the table above to determine which graph fits those coordinates.

Make sure that:

  • (0, -3) has an open dot
  • nothing is plotted between x = 0 and x = 2
  • (2, -4) has a closed dot
