36/42
multiply the top and bottom by 6.
7 x 6 = 42
6 x 6= 36
Considering that the grows at a constant rate we can form an equation where x = how many years after it was planted
and y = its height
Now we just need to find how many feet it grows each year. To do that we just need to compare its height from a certain age to another:
6 years after it was planted : 7 feet,
so x=6 and y = 7
9 years after it was planted: 16 feet
so x= 9 y=16
With thay we can conclude that in 3 years , the tree grew 9 feet. To discover how much the tree grow each year we just nee to divide 9 feet by 3 years which is 3 feet every year.
To write the equatopn now we just need to find the y-intercept which we can discover by setting x to 0:
If in 6 years after the tree was planted it is 7 feet long , we can discover how long it was when it was planted by subtracting 6 years of growth (The slope ) which is 3
7 - 6(years)×3(feet the tree grow each year)
7 - 18 = -11
The tree was -11 feet long when it was planted
which is our y-intercept
( I know it doesnt make sense , but if you apply to a graph it will make more sense )
Now we can make the equation
y = 3x -11
Answer:
the total cost would be $45.2
Answer and Step-by-step explanation:
Essentially, you are describing the position of point K using the location of the other points on the graph.
<u>Let's start listing some descriptions:</u>
K is:
<em>3 more than H</em>
<em>2 more than J</em>
<em>3 less than L</em>
<em>4 less than M</em>
<em>7 less than N</em>
<em>12 less than P</em>
<em />
<u>Now look at the answer choices and compare it to what we wrote.</u>
We see that the answer choices A, B, and D are incorrect (based on what we wrote), and that answer choice C is correct.
<u>[C. 7 less than N] is the correct answer.</u>
