The question is in the photo. Answer part d

Answer

your equation in part c is wrong

Step-by-step explanation:

part c

y=mx+c

11=2m+c(1)

15=3m+c(2)

(2)-(1)

15-11=(3m+c)-(2m+c)

4=3m-2m+c-c

m=4

substitute in (1)

2m+c=11

2*4+c=11

8+c=11

c=3

so equation should be y=4x+3

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
