A rational number can be written as "a ratio of integers".
(That's a fancy name for "a fraction".)
Answer:
C
Step-by-step explanation:
You take Photographer B's hours and subtract them. 110-80=30. You know that there is an hour between so you can split 30 in half to get 15. Now that you know Photographer B is charging 15 an hour you can take 80 and subtract 15 twice because it cost 80 at 2 hours. You subtract 30 from 80 and you get 50.
Answer:
360
Step-by-step explanation:
You do 3 times 14 and you get 42
y = 4x+5 is in the form y = mx+b which is slope intercept form. Anything in y = mx+b form is linear. It graphs out a straight line.
Contrast this with y = x^2 which is nonlinear because it graphs a curve that isnt a straight line. All quadratics like this graph out a parabola which resembles a bowl shaped curve.
