the circle graph shows the percentage of six different bird species that were spotted in the bird feeder the number matches species were one bluebirds. 2 Cardinals .3 chickadees 4 Finches 5 nuthatches 6 sparrow.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
