Please help I’ll mark brainliest as long as u tell me how u got that answer :)

B i think

Step-by-step explanation: The numbers 79,340 and 210,00 go together. The rest of the numbers go together as well.

D.

Step-by-step explanation:

You can eliminate A because Beth gets a raise of 210 dollars per year. You can also eliminate B because the equal sign indicates how much years will it take for Beth and Robert earn the same amount. So now it leaves C and D. You can eliminate C because 79,340 is added to 210y, so each year, y, the raise will be 210 per year. But C uses 840y, which isn’t right. This leaves D to be the right answer. Hope this helps. If you have any questions or concerns, feel free to comment them below!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
