Solve the systems of equations using elimination
3x-5y=-2
4x-7y=-3
,-1)
b.( -7/3, -1)
c. (-7/3, 1)
d.(1, 1)

x=1, y=1. (1, 1). The answer is D).

Step-by-step explanation:

3x-5y=-2

4x-7y=-3

4(3x-5y)=4(-2)

-3(4x-7y)=-3(-3)

12x-20y=-8

-12x+21y=9

y=1

3x-5(1)=-2

3x-5=-2

3x=-2+5

3x=3

x=3/3

x=1

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

step-by-step explanation:
