Answer:

\boxed{B. \: 5 {x}^{6}  + 5 {x}^{5}  + 8 {x}^{2}  - x + 2}

Step-by-step explanation:

=  > (2 {x}^{6}  + 8 {x}^{2} - x + 1) + (3 {x}^{6} + 5 {x}^{5}  + 1) \\  \\  =  > 2 {x}^{6}  + 8 {x}^{2} - x + 1 + 3 {x}^{6} + 5 {x}^{5}  + 1 \\  \\  =  > 2 {x}^{6}  + 3 {x}^{6}  + 5 {x}^{5}  + 8 {x}^{2}  - x + 1 + 1 \\  \\  =  > 5 {x}^{6}  + 5 {x}^{5}  + 8 {x}^{2}  - x + 2

F(x)=x^2-x-1 What is the average rate of change of f over the interval -1<=x<=1
nalin [4]
In calculus, we use derivatives to find the instantaneous rate of change at any point on a graph. To find the average rate of change, we just find the slope of the secant line that intercepts two points on the graph.

We find slope with the following equation:

m =  \frac{y_1 - y_2}{x_1-x_2}

In this case, we are looking for the slope from x = -1 to x = 1. We have both x values, so next we need the y values.

F(-1) = (-1)^2 - (-1) - 1 = 1

F(1) = (1)^2 - (1) - 1 = -1

Now plug in the x and y values to find the slope:

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

The answer is -1.

The measures of the angles of a triangle are (3x – 100)°, (x – 10)°, and (x – 10)°.
statuscvo [17]

Answer:

x = 60

largest angle = 80°

Step-by-step explanation:

the sum of all three angles in a triangle = 180°

(3x - 100) + (x - 10) + (x - 10) = 180

simplify:

5x = 300

x = 60

angles are 80°, 50°, and 50°
