Answer:

x ≈ - 1.56

x ≈ 2.56

Step-by-step explanation:

x^2 - x = 4

x^2 - x + 1/4 = 17/4

( x - 1/2 )^2 = 17/4

x - 1/2 =Sqrt[17]/2 or x - 1/2 = - (Sqrt[17]/2)

x = 1/2 + Sqrt[17]/2 or x = 1/2 - (Sqrt[17]/2)

The formula - b +- srt(b^2 - 4ac) / 2a could also be used

A group of friends wants to go to the amusement park. They have $246.75 to spend on parking and admission. Parking is $14, and t
bearhunter [10]
<h3>Answer:   7</h3>

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

Explanation:

x = number of people

33.25x = cost of the tickets only, without parking

33.25x+14 = add on the cost of parking

33.25x+14 = 246.75

To solve this equation we'll do these two steps in the order mentioned

  1. Subtract 14 from both sides. This is to undo the +14
  2. Divide both sides by 33.25 to undo the multiplication.

The idea is we follow PEMDAS in reverse undoing everything so we can isolate x.

So,

33.25x+14 = 246.75

33.25x = 246.75-14 ............. step 1 mentioned earlier

33.25x = 232.75

x = 232.75/(33.25)  ................ step 2 mentioned earlier

x = 7 is the final answer

---------------

Check:

7 people go to the amusement park

At $33.25 per person, that amounts to 7*33.25 = 232.75 dollars so far.

Then add the cost of parking to get 232.75+14 = 246.75 to match the total amount spent stated in the instructions. The answer has been confirmed.

Notes:

  • This assumes they all went in the same vehicle.
  • They'll need to bring more money if they want things like food, drinks, souvenirs, playing carnival games to win prizes, etc.

ABC has vertices A(0,6) B(4,6) C(1,3). Sketch a graph of ABC and use it to find the orthocenter of ABC. Then list the steps you
kumpel [21]
<span> Plot the points and draw the triangle. Now you have to draw a line that passes through a point, perpendicular to the triangle side that it's opposite from. Then do that again with a second point. The intersection of these two points will give you the Orthocenter. (You don't need to do it for the third point; it will pass through it anyway, but you only need two intersecting lines to define a point!) Since AB is a horizontal line, it will probably be easiest to start with the line perpendicular to AB that passes through C. You'll find that this is just the vertical line x=1. Now just pick another point and do it again. (Hint: if you know two points, you can find their slope, and you know that lines perpendicular to each other have negative reciprocal slopes.)</span>

I am Lyosha [343]

The amount of quarts of water to fill the jar is 10.6875 quarts

To solve this problem effectively, we need to understand the concept of word problems.

<h3>What are word problems in mathematics?</h3>

Word problems in mathematics are questions that require a crucial understanding and application of mathematical principles to solve them effectively.

From the parameters given:

  • If 114 ounces of water is poured three times to fill the jar

Then, the total amount of ounces that fills the water is:

= 114 ounces × 3

= 342 ounces

From the dimensional analysis of measurements:

1 ounce = 0.03125 quarts

Thus, in quarts, 342 ounces will be:

\mathbf{=\dfrac{ (342 \  ounces \times 0.03125 \ quarts)}{1 \ ounce}}

= 10.6875 quarts
