Answer:
$2,480
Step-by-step explanation:
Let $x be next year tuition. Aiden will pay $2,400, that is 75% of $x.
$x - 100%
$2,400 - 75%
Write a proportion:
Next year’s tuition will be $720 more than this year’s, then this year tuition is
Let Lisa's height be x, Ian's be y and Jim's be z
x = 10 + y . . . (1)
y = 14 + z . . . (2)
y + 14 + z + 14 = 170 + x + 14
y + z - x = 170 + 14 - 28 = 156 . . . (3)
From (2), z = y - 14 . . . (4)
Putting (1) and (4) into (3) gives,
y + y - 14 - 10 - y = 156
y = 156 + 24 = 180
Therefore, Ian's height is 180 centimeters
The critical points of the function graphed are given as follows:
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:
In a graph, they are turning points, and are classified as follows:
- Local maximum, if the functions changes from increasing to decreasing.
- Local minimum, if the functions changes from decreasing to increasing.
Looking at the graph, the turning points are approximately:

Lets simplify this
2x^2 + 2x - 10 _< 2
4x^2 - 10 _< 2
4x^2 _< -8
x^2 _< -2
x _<1.41
on the graph plot a line, then a filled in cirlce at 1.41
Combine all paper clip colors together (3 red+ 5 yellow+ 6 silver) to get 14 paper clips in all.
The number of red clips are 3.
Since it is asking for ratio of total paper clips to red paperclips, the number of total paperclips goes in the ratio goes first and red paperclips second. 14:3.
This ratio cannot be simplified any further so A is the correct answer
Hope this helps!
