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>

The sum of two consecutive even numbers is 210.

WITCHER [35]

Answer:

104, 106

Step-by-step explanation:

Hello!

A consecutive number is a number that comes after the other.

Let the first even integer be x. Since there is an even integer for every two integers, the second number should be x + 2.

<h3>Solve for x</h3>

(x) + (x + 2) = 210
x + x + 2 = 210
2x + 2 = 210
2x = 208
x = 104

The second number is x + 2, so it would be 106.

What is the solution to the inequality 28 > 4 – 2p?

Schach [20]

Answer:

-12 < p

Step-by-step explanation:

28 > 4 – 2p

Subtract 4 from each side

28-4 > 4-4 – 2p

24 > -2p

Divide each side by -2, remembering to flip the inequality

24/-2 < -2p/-2

-12 < p
