Well to give your question an answer the points (as i have graphed them) seem to have the same Y axis. This means that a horizontal line can pass through the points. Horizontal: In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel<span> to the horizon.</span>
I think 28 is the answer to your problem
180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25
Answer:
f(-3)=-25
Step-by-step explanation:
Putx=-3
f(-3)=-(-3)^2+7(-3)-13
f(-3)=9-21-13
f(-3)=-25
I hope this will help you
