Let f(x)=x^2−3x−4 . What is the average rate of change from x = 7 to x = 10?

1 answer:

6 0

So, this is the answers you get from plugging in x = (7 through 10)
x = 7 ... 24
x = 8 ... 36
x = 9 ... 50
x = 10 ... 66

Then you get the rate of changes...

66 - 50 = 16
50 - 36 = 14
36 - 24 = 12

So the average of 16, 14 and 12 (those values added together and then that total divided by the number of values, which is 3) is 14

The average rate of change is 14

Which function has the greater rate of change?

Gnoma [55]

Answer:

Function 1

Step-by-step explanation:

<u>Function 1:</u>

$y=\dfrac{5}{6}x+10$

The rate of change of the function 1 is:

$\dfrac{5}{6}\approx 0.83$

<u>Function 2:</u>

The rate of change of the function 2 is:

$\dfrac{15.75-14.25}{1-(1)}=\dfrac{1.5}{2}=0.75$

Hence, the greater rate of change has function 1.

"A line that goes through (4, 7) and (-2, 1)"

Olenka [21]

Y= x + 3
1. Find the gradient(slope)

1 - 7 / - 2 - 4
=1

2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3

Equation => Y = x + 3

What is the slope of the line?

Hunter-Best [27]

Answer:

<h3>☘ QUESTION☘</h3>

What is the slope of the line?

-3x+5y=2x+3y

<h3>☘ ANSWER☘</h3>

-3x+5y=2x+3y → 2y = 5x → y = (5/2)x.

There are infinitely many ordered pairs that satisfy -3x+5y=2x+3y.
