A system of equations has no solution. If y=8x+7 is one of the equations, which could be the other equation?

A

Step-by-step explanation:

becoz 2(y=8x+7)

so, 2y= 16x+14

the answer is b

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
