8-1 Quadratic Graphs and Their Properties How are the graphs of y 22 and y = - - 6x2 +1 similar? How are they different?
A. They have the same vertex, but they open in opposite directions.
B. They both open in the same direction, but the second graph is wider than the first graph.
о
C. They are both parabolas, but the second graph opens horizontally instead of vertically.
D. They have the same shape and axis of symmetry, but the second graph is shifted up 1 unit.

529 and 531

step-by-step explanation:

the answer to this question is 3/19

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

homozygous. one is homozygous, while two is heterozygous.
