Answer:
7
Step-by-step explanation:
The average rate of change of f(x) in the close interval [ a, b ] is
Here [ a, b ] = [2, 5 ]
f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15
f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus
average rate of change = 
= 
= 7
The circle: x = 4 y = 0.5
The square: x = 3.5 y = 1.5
The triangle: x = 0 y = 2.5
The right step followed in the system to get he equations is (D). To get the system B. The second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution of system A.
<h3>Meaning of Simultaneous Equation.</h3>
A simultaneous equation can be defined as an equation that possesses two unknowns and one constant.
The solution to the problem can only be gotten by solving it side by side with another equation of the same format.
In conclusion, The right step followed in the system to get he equations is (D). To get the system B. The second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution of system A.

Answer:
The answer is 25/6 < x < 50/3
Step-by-step explanation:
Move all terms not containing x from the center section of the inequality.

Brainly, please?
The first thing you do is substitute 9 for y in the function, which is,
9 - 4 = 5/6 (x - 2)
Then, you subtract on the left side
5 = 5/6 (x - 2)
Then, you multiply by 6 on both sides
30 = 5 (x - 2)
Then, divide both sides by 5
6 = x - 2
Then, at 2 on both sides to isolate x
& your final answer is
x = 8 (this would be the missing value)
