I believe anything that is squared (^2) is a quadratic. so a, b, e and f are quadratics. you could also check on desmos to see if they are parabolas (u shape).
Answer:
x < -1
Step-by-step explanation:
Solve -.4x-1.2 >.8 for x.
Start by adding 1.2 to both sides, to isolate -0.4 x:
-0.4x > 0.4
Divide both sides by -0.4, remembering the reverse the direction of the inequality sign:
x < -1
Answer:
3.6 gB
Step-by-step explanation:
You can think of this question in terms of the y = mx+b equation.
$78.90 is y because it is the total amount per month, $4 is m because it is the cost per gB, and $64.50 is b because it is the flat rate.
78.9 = 4x + 64.5
4x = 14.4
x = 3.6 gB of data (or 3 if it wants a whole number)
