Answer: False.

Step-by-step explanation:

The slope is the difference in the y coordinates of any two points being divided by the difference between the x coordinates of the same two points.

Using the point, (0,5) and (3,3) find the difference in the y coordinates and divide it by the difference in the x coordinates to find the slope.

y: 5 - 3 = 2

x : 0 - 3 = -3

Slope: -2/3

This is indeed true because line is going downright so the slope has to be negative.

What is the solution for x? x/5=2

Naddika [18.5K]

☁️ Answer ☁️

10, x = 10

x/5=2

simplify the equation to the form

x/5=2

Simplifying:

+ 0.2x=2

move all terms containing x to the left and all other terms to the right.

+ 0.2x=+2

simplify left and right side of the equation.

+ 0.2x=+2

divide both sides of the equation by 0.2 to get x.

x=10

Hope it helps.

Given the function f(x)=x^2-8x+13f(x)=x, determine the average rate of change of the function over the interval −1≤x≤6.

Ann [662]

Given:

Consider the given function is:

$f(x)=x^2-8x+13$

To find:

The average rate of change of the function over the interval $-1\leq x\leq 6$ .

Solution:

The average rate of change of the function f(x) over the interval [a,b] is:

$m=\dfrac{f(x_2)-f(x_1)}{x_2-x_1}$

We have,

$f(x)=x^2-8x+13$

At $x=-1$ ,

$f(-1)=(-1)^2-8(-1)+13$

$f(-1)=1+8+13$

$f(-1)=22$

At $x=6$ ,

$f(6)=(6)^2-8(6)+13$

$f(6)=36-48+13$

$f(6)=1$

Now, the average rate of change of the function f(x) over the interval $-1\leq x\leq 6$ is:

$m=\dfrac{f(6)-f(-1)}{6-(-1)}$

$m=\dfrac{1-22}{7}$

$m=\dfrac{-21}{7}$

$m=-3$

Therefore, the average rate of change of the function f(x) over the interval $-1\leq x\leq 6$ is -3.
