I'll do a similar problem, and I challenge you to do this on your own using similar strategies!
Take y > 7x+2
Plugging in the origin, we have (0,0) as our points, and 0 > 0*7+2=2, so 0>2. As 0 is not greater than 2 (less than is the way that it's pointing), this is false. In addition, as it is y greater than 7x+2, the shaded area is above the line due to that y is greater than, and since y is up and down, greater than means higher than.
Good luck, and feel free to ask any questions that come up!

Answer:
A = 76.85
B =65.28
Step-by-step explanation:
(30/100)A = 10 + (20/100)B
0.3A - 0.2B = 10 ...... equation (i)
(30/100)B + 35 = (20/100)A
0.2A - 0.3B = 35 ........ equation (ii)
From equation (i)
0.3A = 10 - 0.2B
A = (10 - 0.2b) / 0.3
A = 33.33 - 0.67B ........equation (iii)
Put equation (iii) into equation (ii)
0.2(33.33 - 0.67B) - 0.3B = 35
6.67 - 0.134B - 0.3B = 35
0.434B = 35 - 6.67
B = 28.33 / 0.434
B = 65. 275 = 65.28
Put B = 65.28 into equation (i)
0.3A - 0.2B = 10
0.3A - 0.2(65.28) = 10
0.3A - 13.056 = 10
0.3A = 10 + 13.056
A = 23.056/ 0.3
A = 76.85
Answer:
D
Step-by-step explanation:
my sister had the same question
Answer:
Correct option is c.
Step-by-step explanation:
The information provided is:
- It costs $83 a day to rent a car plus a required fee for insurance.
- The total cost for renting the car for 7 days is $621.
Then the cost of renting the car for 7 days will be, (83 × 7).
Let <em>b</em> denote the required fee for insurance.
Then the equation representing the total cost of renting is:
621 = 83(7) + b
Compute the value of <em>b</em> as follows:
621 = 83(7) + b
621 = 581 + b
b = 40
So, the correct option is c.
