4) n - 5/4 - 1 3/4 = -7/2 + 4/3n

3/2=n

Step-by-step explanation:

add (-5/4) and (-7/4) to get -3. Add (-7/2) to the left side to get (1/2). subtract n from both sides to get 1/2=(1/3n).multiply both sides by 3 to find the answer for n which is 3/2.

it is probably the graph on the bottom right.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
