Rearrange 3x - 6y = -2 to the form y=mx + c

wel

3x - 6y = -2

-6y = -3x - 2, divide through by -1

6y = 3x + 2, divide through by 6

y = 3x/6 + 2/6

y = x/2 + 1/3

Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15

Solution:

The function that models the yield is:

$f(x) = -x^2 + 20x + 75$

The average rate of change of f(x) from x = a to x = b is given by the formula:

$\text{ average rate of change }=\frac{f(b)-f(a)}{b-a}$

Find and interpret the average rate of change from year 5 to year 15

$f(5) = -(5)^2 + 20(5) + 75\\\\f(5) = -25 + 100 + 75\\\\f(5) = 150$

$f(15) = - (15)^2 + 20(15) + 75\\\\f(15) = -225 + 300 + 75\\\\f(15) = 150$

Thus average rate of change:

$\text {average rate of change}=\frac{f(15)-f(5)}{15-5}$

$\text {average rate of change}=\frac{150-150}{10}=0$

Thus Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15.

1225*(1.578*10^-5)=1.933*10^-2

1.578*10^-5= 0.00001578

1225*0.00001578=0.0193305

0.0193305=1.933*10^-2

The students at view side elementary school had a read a thon the teachers kept track of how many books the students in each gra

inn [45]

Answer:

Estimate = 3400 books

Step-by-step explanation:

Given that:

Books read by students.

Kindergarten 247

First grade 385

Second grade 1347

Third grade 1549

We have to round the each number to nearest hundred.

247 rounded to the nearest hundred is 200.

385 rounded is 400

1347 rounded is 1300

1549 rounded is 1500

Total = 200 + 400 + 1300 + 1500 = 3400

Hence,

Estimate = 3400 books
