7. what is the graph of the inequality in the coordinate plane? <br><br> x&gt;=1
sasho [114]
Because x is greater than, or equal to one, your graph would be a solid vertical line, along the 1 value. The right side of this line would be shaded, because your inequality includes everything to the right of this line.

Jim and Stephanie just got married and are thinking about changing their health care insurance plans to be more affordable. Curr
insens350 [35]

Answer:

Option B is correct.

Stephanie should add Jim to her health care plan.

Step-by-step explanation:

Let's take the options one by one.

Option 1

If Jim's employers insure him and his wife.

Jim’s employer pays 42% of his $378 monthly premium. His insurance plan will also pay for 23% of the $345 premium for additional beneficiaries.

It means Jim will pay (0.58 of $378) for himself plus (0.73 of $345) for his wife.

Amount Jim pays = (0.58 × 378) + (0.73 × 345) = $471.09

Option 2

If Stephanie's employers insure both of them.

Stephanie’s employer pays 35% of her $298 monthly premium but offers to pay an extra 10% of her premium for each beneficiary Stephanie adds to her plan. Her employer would then pay 30% of the $349 premium for each additional beneficiary.

It means Stephanie would pay (0.65 of $298) she'll pay for herself plus (0.70 of $349) she'll pay for her husband minus (10% of $298) that her company wants to pay out of the insurance fee of any of her additional beneficiary.

Amount Stephanie will pay = (0.65 × 298) + (0.70 × 349) - (0.10 × 298) = $408.2

Option 3

If each of them does an insurance plan with their respective employers

Jim’s employer pays 42% of his $378 monthly premium.

Stephanie’s employer pays 35% of her $298 monthly premium

Jim would pay (0.58 × $378) for himself = $219.24

Stephanie would pay (0.65 × $298) for herself = $193.7

Total they would pay in this option = $219.24 + $193.7 = $412.94

Of all the three options, the option that minimizes their expenses is when Stephanie insures herself and Jim with her employers for a total cost of $408.2 compared to a total cost of $471.09 if Jim insures the two of them with his employers or $412.94 if they respectively insure each other with their respective employers.

Hope this Helps!!!

Joe drove 200 km in 4 hours.At what rate did he drive?<br><br><br>​
Mandarinka [93]

Answer

50mph

Step-by-step explanation:  

rt=d use the rate times time equals distance method.

it gives us the time=4, use an exponent to represent the rate(since that's the information we don't have equals 200km

x times 4 = 200km

4x = 200km

divide by 4 to leave the exponent by itself

x = 50km
