What is the rate of change of the function shown on the graph? Round to the nearest tenth.

faltersainse [42]

<u>Answer</u>:

The required is the multiplicative rate of change.

The correct answer is the second option<u> 2.5</u>

<u>Step-by-step explanation:</u>

The given function has the form of the exponential function

The general equation of the exponential function $y=c * r^x$

Wher c is constant and r is the multiplicative rate of change.

Using the given points to get the values of c and r

By using the point (0,2) ⇒∴ $2=c * r^0$ ⇒ c = 2

By using the point (1,5) ⇒∴ $5=2 * r^1$ ⇒ r = 5/2 = 2.5

Check the answer using the other points

If x = 2 ⇒⇒⇒ $y=2 * 2.5^2 = 12.5$

If x = -1 ⇒⇒⇒ y=2 * 2.5^(-1) = 0.8

<u>So, the multiplicative rate of change = 2.5</u>

A line that includes the point (4, 7) has a slope of 3. What is its equation in slope-intercept form?

vampirchik [111]

Answer: slope intercept is solve for y

Step-by-step explanation:

point slope

y-y1=m(x1,y1) and the slope is m

given

slope=3

a point i (4,7)

y-7=3(x-4)

solve for y

y-7=3x-12

add 7 both sides

y=3x-5 is slope intercept form

HELP!!!!!!! Choose the graph that matches the following system of equations:

pshichka [43]

Answer:

The answer in the attached figure

Step-by-step explanation:

we have

$4x + 2y = -2$ -----> equation A

$x-3y=24$ -----> equation B

Isolate the variable x in the equation B

$x=3y+24$ ----> substitute in the equation A and solve for y

$4(3y+24) + 2y = -2$

$12y+96+ 2y = -2$

$14y = -2-96$

$14y = -98$

$y = -7$

Find the value of x

$x=3(-7)+24=3$

The solution of the system of equations is the point (3,-7)
