Let x be the number of gigabyte of data used.
Plan A:
Total cost = 30 + 5x
Plan B:
Total cost = 50 + 2x
Irfan will use between 5 to 8 gb of data per month.
When x = 5
Plan A = 30 + 5(5) = $55
When x = 8,
Plan A = 30 + 5(8) = $70
When x =5,
Plan B = 50 + 2(5) = $60
When x = 8,
Plan B = 50 + 2(8) = $68
He is probably better off using Plan A. Plan A is a cheaper option up to 7gb of data. He should only swap to Plan B if he consistently use 8gb or more data per month.
Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
15 + 8= 23
23/2 = 11.2
-5 + 8 = 3
3/2= 1.5
Answer is (11.2,1.5)
Using the sine law of triangles to solve for angle C:
b / sin B = c / sin C
C = arcsin (c * sin B / b)
C = 30.7<span>°
Since interior angles of a triangle always add up to 180</span><span>°, we can use this to solve for angle A:
angle A = 180</span>° - 73° - 30.7<span>°
angle A = 76.3</span><span>°
Having solved for angle A, we can solve for side a using the sine law.
a / sin A = b / sin B
a = b * sin A / sin B
a = 15.2
Therefore, the correct answer is B.</span>
Y=4 because every y value is 4 and x is infinite
