Make x the subject of y = 4x + 1
You may use the flowchart to help you if you wish.

x =

Step-by-step explanation:

Given

y = 4x + 1 ( subtract 1 from both sides )

y - 1 = 4x ( divide both sides by 4 )

= x

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
