Answer: OPTION B

Step-by-step explanation:

As you can see in the graph, when x=1, y=3 and when x=4, y=0

Then, draw a line that cut the points (1,3) and (4,0), as you can see in the image attached, and calculate the slope (which represents the average rate of change of the function), with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{0-3}{4-1}=-1

Therefore, the aswer is the option B.

ANSWER

B) -1

EXPLANATION

From the graph,

f(1)=3 and f(4)=0.

The average rate of change from x=1 to x=4 of this function is,

= \frac{f(4) - f(1)}{4 - 1}

Substitute the functional values

= \frac{0 - 3}{3}

Simplify

= \frac{-3}{3} = -1

The correct choice is .

Answer: 103/15

Step-by-step explanation:

We can simplify the right-hand side to be 2 \left(\frac{1}{3}+6 \right)=2 \left(\frac{19}{3} \right)=\frac{38}{3}.

This means we need to solve:

\frac{1}{2}(5x-9)=\frac{38}{3}\\5x-9=\frac{76}{3}\\5x=\frac{103}{3}\\x=\boxed{\frac{103}{15}}

If you were to solve the following system by substitution, what would be the best variable to solve for and from what equation?
zepelin [54]
Honestly this problem you can use both x and y but x tends to be the easier one to use and i would use the first equation because it is easier to solve because all the numbers are even.<span />
