Step-by-step explanation:

Pt.1

  • Andre kick highest kick yardage was 17.
  • We can find Juana kick yard by doing the extremes quadratic rule

\frac{ - b}{2a}

where b is the coefficient and a is the leading coefficient.

\frac{ - 14}{ - 2}  = 7

Plug 7 in for x.

-  {7}^{2}  + 14(7) - 24 = 25

  • So joanna yardage is 25.
  • Kevin max yardage looks between 10 and 15.
  • Emilio max yardage is 20

Juanna has kicked the highest.

<em>Pt.2</em><em>.</em><em> </em><em>We</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>who</em><em> </em><em>kicked</em><em> </em><em>the</em><em> </em><em>longest</em><em>.</em>

  • <em>Andre</em><em> </em><em>started</em><em> </em><em>at</em><em> </em><em>1</em><em>2</em><em> </em><em>and</em><em> </em><em>finished</em><em> </em><em>at</em><em> </em><em>4</em><em>8</em><em> </em><em>so</em><em> </em><em>he</em><em> </em><em>kicked</em><em> </em><em>3</em><em>6</em><em> </em><em>yards</em>
  • <em>Kevin</em><em> </em><em>started</em><em> </em><em>at</em><em> </em><em>0</em><em> </em><em>and</em><em> </em><em>ended</em><em> </em><em>at</em><em> </em><em>2</em><em>0</em><em> </em><em>so</em><em> </em><em>he</em><em> </em><em>kicked</em><em> </em><em>2</em><em>0</em><em> </em><em>yards</em><em>.</em>

<em>We</em><em> </em><em>can</em><em> </em><em>find</em><em> </em><em>Juanna</em><em> </em><em>and</em><em> </em><em>Emiko</em><em> </em><em>where</em><em> </em><em>she</em><em> </em><em>started</em><em> </em><em>and</em><em> </em><em>ended</em><em>.</em>

<em>Emiko</em><em>:</em>

<em>Notice</em><em> </em><em>how</em><em> </em><em>she</em><em> </em><em>starts</em><em> </em><em>at</em><em> </em><em>1</em><em>0</em><em> </em><em>and</em><em> </em><em>her</em><em> </em><em>max</em><em>,</em><em>2</em><em>0</em><em> </em><em>is</em><em> </em><em>at</em><em> </em><em>when</em><em> </em><em>x</em><em>=</em><em>1</em><em>8</em><em> </em><em>then</em><em> </em><em>it</em><em> </em><em>starts</em><em> </em><em>decreasing</em><em> </em><em>so</em><em> </em><em>this</em><em> </em><em>means</em><em> </em><em>at</em>

<em>x</em><em>=</em><em>2</em><em>6</em><em>,</em><em> </em><em>she</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>at</em><em> </em><em>ground</em><em> </em><em>level</em><em> </em><em>again</em><em> </em><em>so</em><em> </em>

  • <em>her</em><em> </em><em>kick</em><em> </em><em>yardage</em><em> </em><em>is</em><em> </em><em>1</em><em>6</em><em>.</em>

<em>Juanna</em><em>:</em>

<em>We</em><em> </em><em>can</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>roots</em><em> </em><em>to</em><em> </em><em>make</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>zero</em><em>.</em>

<em>-  {x}^{2}  + 14x - 24</em>

<em>Factor</em><em> </em><em>out</em><em> </em><em>a</em><em> </em><em>-</em>

<em>- ( {x}^{2}  - 14x + 24)</em>

<em>We</em><em> </em><em>must</em><em> </em><em>think</em><em> </em><em>of</em><em> </em><em>two</em><em> </em><em>numbers</em><em> </em><em>that</em><em> </em><em>add</em><em> </em><em>to</em><em> </em><em>negative</em><em> </em><em>1</em><em>4</em><em> </em><em>and</em><em> </em><em>multiply</em><em> </em><em>to</em><em> </em><em>24</em><em>.</em>

<em>(x - 12)(x - 2)</em>

<em>Set</em><em> </em><em>both</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>zero</em><em>.</em>

<em>x - 12 = 0</em>

<em>x = 12</em>

<em>x - 2 = 0</em>

<em>x = 2</em>

<em>So</em><em> </em><em>this</em><em> </em><em>means</em><em> </em><em>that</em><em> </em>

  • <em>Joanna</em><em> </em><em>kick</em><em> </em><em>yardage</em><em> </em><em>was</em><em> </em><em>1</em><em>0</em>
  • <em>This</em><em> </em><em>means</em><em> </em><em>Andre</em><em> </em><em>kicked</em><em> </em><em>the</em><em> </em><em>farthest</em><em>.</em>

Si en 1950 el 30% de la población global, alrededor de 700 millones de personas habitaban
kramer

Answer:

zonas urbanas =>  30  % de la poblacion => 700 millones

poblacion total =>  100 % de la poblacion =>   x      =>  2333.3 millones

poblacion rural => 70% de la poblacion => x - 700  => 1633.33 millones

x = \frac{700 \times100}{30} =2333.3

x-700=2333.3-700=1633.33\\

tickets for a harlem globetrotter show cost $28 general admission, $43 courtside, or $173 bench seats. Nine times as many genera
densk [106]

Answer:

general admission tickets  1170

courtside tickets  985

tickets bench seats.  130

Step-by-step explanation:

To solve the problem, it is necessary to generate a system of equations with the information provided by the statement.

First be

x = # general admission tickets

y = # courtside tickets

z = # tickets bench seats.

The first equation would be that they sold nine times more general admission tickets than bench seats tickets.

That is: x = 9 * z (1)

And the second equation is that the number of general admission tickets sold was 55 more than the sum of the number of courtside tickets and bench seats tickets.

That is: x = 55 + y + z (2)

Now the third equation would be the money raised.

28 * x + 43 * y + 173 * z = 97605 (3)

Now if I replace I rearrange (1):

z = x / 9 (4) and replacement in 2, I have:

x = 55 + y + x / 9, rearranging:

y = (8/9) * x - 55 (5)

Now replacing (4) and (5) in 3, we have:

28 * x + 43 * ((8/9) * x - 55) + 173 * (x / 9) = 97605

Solving the above:

x = 1170, therefore

y = (8/9) * 1170 55 = 985

z = 1170/9 = 130

We can confirm this with equation (3)

28 * x + 43 * y + 173 * z = 97605

28 * 1170 + 43 * 985 + 173 * 130 = 97605

Pls help solve question 3
Lelu [443]

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab  = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

40

so, the value of ab is 40

What is the sum of the fractions? Use the number line and equivalent fractions to help find the answer.
Alchen [17]
<h3>Answer:  -3/4  (choice C)</h3>

==================================================

Explanation:

Think of a whole cake or pizza. Now slice it into 4 equal pieces. This represents 1 is the same as 4/4.

Adding on another quarter slice gets us 4/4+1/4 = 5/4

In other words, the mixed number 1 & 1/4 is the same as the improper fraction 5/4.

So 1 & 1/4 = 5/4

This then means -1 & 1/4 = -5/4 because we multiply both sides by -1.

Now we'll add on 1/2, which is the same as 2/4, like so

(-1 & 1/4) + 1/2

-(1 & 1/4) + 2/4

-(1 + 1/4) + 2/4

-1 - 1/4 + 2/4

-1 + (-1/4 + 2/4)

-1 + 1/4

-4/4 + 1/4

-3/4

which points us to choice C as our final answer

Notice how if we started at -5/4, and moved to the right 2 tickmarks, we arrive at -3/4. Each tickmark represents 1/4 of a unit, so two of them is 2/4 = 1/2.

Side note: -3/4 converts to the decimal -0.75
