Answer: 2

Step-by-step explanation:

They are saying that x equals 2, and the question is what the function is defined at when x = 2

Going to x = 2, the y value is just 2

For questions 5 and 6, solve the system using the Elimination method.

beks73 [17]

Answer:

$\boxed{x = 7~~and~~y = -3}$

Step-by-step explanation:

5x + 3y = 26 (times 6) 30x + 18y = 156

6x + 7y = 21 (times 5) 30x + 35y = 105

30x + 18y = 156

30x + 35y = 105

-17y = 51

$y = \frac{51}{-17}$

y = -3

Substitute the value of y to one of equations

6x + 7y = 21

6x + 7(-3) = 21

6x - 21 = 21

6x = 21 + 21

6x = 42

$x = \frac{42}{6}$

x = 7

What is the slope of the line? A. 2/5 B. -2/5 C. 5/2 D. -5/2

sergey [27]

Answer:

B. -2/5

Step-by-step explanation:

For a "run" (x change) of 5, the "rise" (y change) is -2 units. Then the slope is ...

slope = rise/run = -2/5

What is the average rate of change of the function over the interval x = 0 to x = 8?

salantis [7]

Ans: The average rate of change of function = $\frac{1}{102}$ (in fraction)

Explanation:
The average rate of change of function = $\frac{f(b) - f(a)}{b - a}$

Where
b = 8 (x's upper bound)
a = 0 (x's lower bound)

$f(b) = f(8) = \frac{2*8-2}{5*8-6} = \frac{7}{17} \\ f(a) = f(0) = \frac{2*0-2}{5*0-6} = \frac{1}{3} \\ \frac{f(b) - f(a)}{b-a} = \frac{ \frac{7}{17} - \frac{1}{3}}{8} = \frac{1}{102}$

Hence the average rate of change of function = $\frac{1}{102}$ (in fraction)
