Examine the system of equations.
y = 3
2
x − 6,
y = −9
2
x + 21
Use substitution to solve the system of equations. What is the value of y?

y =

y=32x-6

y=-92×+21

32x-6=-92x+21

-32. -32

-6=124x+21

-27=- 124x

27/124

x= 0.21

y=32(0.21)-6

y=6.72-6

y =.72

sorry if my answer is not correct

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

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
