At the grocery store, 8 oranges cost $4. What is the cost for 9 oranges

$4.50

Step-by-step explanation:

First you find the cost of each orange

4 divided by 8 = 0.5

so if each orange is $0.5 you can multiply it by 9 which is the amount of oranges there are

9 * 0.5 = $4.50

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
