Answer:

A: save $250 per month for the next 3 years

Step-by-step explanation:

Melinda has three more years in high school as stated in the question.

One year private university tuition = $22,500

Support from family = $13,500

Amount that Melinda has to pay = $22,500 - $13,500 = $9000

Number of months in three years = 3 * 12 = 36 months

If she must save $9000 in 36 months

Then $x  must be saved in 1 month

x = $9000/36

x = $250

3. The average red blood cell has a thickness of 0.0000024 m. Write this number in scientific notation.
vazorg [7]

Answer:

  a) 24×10^-7

Step-by-step explanation:

The number is ...

  0.0000024 = 2.4×0.000001 = 24×0.0000001

The first of these equivalents can be written as ...

  2.4×10^-6 . . . . matches no answer choice (correct answer)

The second of these can be written as ...

  24×10^-7 . . . . matches choice (a)

__

Usually "scientific notation" requires there be one digit left of the decimal point in the mantissa. As we have noted above, no offered answer choice matches this form. The only choice that is equivalent to the given number is the one shown above.

What is the product of -3 1/4 × -1 1/2​
Dmitry [639]

For this case we must find the product of the following expression:

-3 \frac {1} {4} * - 1 \frac {1} {2} =

So, we have:

(\frac {4 * (3) +1} {4}) * (\frac {2 * (1) +1} {2}) =\\\frac {12 + 1} {4} * \frac {2 + 1} {2} =\\(- \frac {13} {4}) * (- \frac {3} {2}) =

By law of signs of multiplication is fulfilled:

- * - = +\\\frac {13 * 3} {4 * 2} =\\\frac {39} {8}

ANswer:

\frac {39} {8}

Mhanifa can you please help? I will mark brainliest!

Answer:

<u>Given function</u>

  • h(x) = 2x - 1

#15 Find the inverse of h(x)

<u>Substitute x with y and h(x) with x and solve for y:</u>

  • x = 2y - 1
  • 2y = x + 1
  • y = 1/2x + 1/2

<u>The inverse is:</u>

  • h⁻¹(x) = 1/2x + 1/2

#16 The graph with both lines is attached.

The x- and y-intercepts of both functions have reversed values.

#17 Table of the inverse function  will contain same numbers with swapped domain and range.

<u>Initial look is like this:</u>

  • <u>x        |  -3  |  -2  | -1  |  0  |    1  |  2  | 3</u>
  • h⁻¹(x)  |  -1   |       | 0   |      |    1  |      | 2

<u>The rest of the table is filled in by finding the values:</u>

  • <u>x        |  -3  |  -2    | -1  |  0   |  1  |  2   | 3</u>
  • h⁻¹(x)  |  -1   | -0.5 |  0  | 0.5 |  1  | 1.5 | 2

I need to remember how to solve this problem
bekas [8.4K]

<u>1 + 4x = -5 + 7x</u>

1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:

1+5=7x-4x

2nd step:

3x=6

3rd step: you need to divide both sides into 3, because it is the common divisor.

x=2

<h2>To sum up:</h2>

<em>1 + 4x = -5+7x</em>

<em>7x - 4x = 1 + 5</em>

<em>3x = 6</em>

<h2><em>x = 2</em></h2>

You can try to memorize the summary. However, it is better to understand the solution as a whole.
