Answer:

The slope is -2.

Step-by-step explanation:

m=y2-y1/x2-x1 (also, y1-y2/x1-x2 is also true.)

=23-15/6-10 m=15-23/10-6

= 8/-4 =-8/4

=4/-2 =-4/2

= 2/-1 =-2/1

m=-2 m=-2

Find the average rate of change of the function between the given values of x. y = 9+ 5x + 0.5x2 between x = 2 and x = 4.

svet-max [94.6K]

Answer:

The average rate of change is 8.

Step-by-step explanation:

The formula to calculate the average rate of change of a function F(x) is:

$\frac{F(b)-F(a)}{b-a}$

In this case, F(x) = $0.5x^{2} +5x+9$

a=2 and b=4

You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.

In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:

F(b) = $(0.5)4^{2} + 5(4) +9= 37$

F(a) = $(0.5)2^{2} + 5(2)+9=21$

$\frac{F(b)-F(a)}{b-a} = \frac{37-21}{4-2}=\frac{16}{2} = 8$

The answer is 8.

Find the value of x.<br> A) 55<br> B) 60<br> C) 70<br> D) 125

Anna11 [10]

Answer:

x = 70°

Step-by-step explanation:

The given triangle has 2 equal sides and is therefore isosceles.

The base angles are equal, both 55°

To find x subtract the sum of the 2 angles from 180

x = 180° - (55 + 55)° = 180° - 110° = 70°
