M = 4
Because the base of log is 10
10,000 is 10*4, and we know that log 10,000 =4, so M=4

Find the slope of the given points (2,5) and (8,-3) and write the equation​
max2010maxim [7]

Answer:

Slope = \frac{-4}{3}

4x + 3y = 23

Step-by-step explanation:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}

The equation:

\frac{y-y_{1} }{x-x_{1} }=m   m is the slope

y-y_{1}=m(x-x_{1} )

y - 5 = -4/3 (x - 2) Multiply both sides by 3

3y -15 = -4 (x - 2)  

3y - 15 = -4x + 8

3y + 4x = 8 + 15

3y + 4x = 23

4x + 3y = 23

Mrac [35]

Answer: 150 + 10x =270

Step-by-step explanation:

So basically she makes $150 per week automatically so u can write that. Then, she makes 10 dollars for each pocketbook she sells so that times x since we don’t know how many pocket books.

If u were to actually have to write how many pocket books you would do 270-150= 120. Then, 120/10= 12 pocketbooks.

What kind of quadrilateral is PQRS? EXPLAIN YOUR REASONING.
aleksandr82 [10.1K]

Answer:

  1. PS = 3
  2. SR = 3
  3. PQ = √29
  4. QR = √29
  5. kite

Step-by-step explanation:

A quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a <em>kite</em>.

Perhaps a more conventional definition of a kite is that it is a quadrilateral with two pairs of congruent adjacent sides.

<h3>1, 2)</h3>

The lengths PS and SR can be found by counting grid squares along the line segments. Each has a length of 3. They constitute one pair of congruent adjacent sides.

  PS = SR = 3

__

<h3>3, 4)</h3>

The lengths of PQ an QR can be found using the distance formula. Essentially, it uses the Pythagorean theorem to compute the hypotenuse of a right triangle whose legs are the differences in x- and y-coordinates. For PQ and QR, those differences are 2 and 5, so the lengths of those segments are √(2² +5²) = √29.

  PQ = QR = √29

__

<h3>5)</h3>

The figure has two pairs of congruent adjacent sides, so is a <em>kite</em>.
