Answer:

$2.50$

Step-by-step explanation:

Given

$(x_1,y_1) = (-1,0.8)$

$(x_2,y_2) = (0,2)$

$(x_3,y_3) = (1,5)$

$(x_4,y_4) = (2,12.5)$

Required

The rate of change (b)

The above graph is represented as:

$y = ab^x$

For: $(x_2,y_2) = (0,2)$ ;

We have:

$y = ab^x$

$2 = a * b^0$

$2 = a *1$

$2 = a$

$a = 2$

For $(x_3,y_3) = (1,5)$ ,

We have:

$y = ab^x$

$5 = a * b^1$

$5 = a * b$

Substitute $a = 2$

$5 = 2 * b$

Divide by 2

$2.5 = b$

$b = 2.5$

<em>Hence, the rate of change is 2.50</em>

Please help and thank you

Answer: c

Step-by-step explanation:

The two points on the line are open, so they will not be included in the solution set, which means they will be greater than or less than. No number can fit both inequalities, so it must be “or”. The only one that fits this is c.

x = 130 is your answer

130 - 20 = 110

Since line E and F are parallel and are straight lines, we know both angles will add up to 180°

110 + 70 = 180
