Answer: -2x + 5y = 8
Step-by-step explanation:
Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y
Substitute the values of x and y from the given coordinate (6,4) to find the new constant, b, the y-intercept.
-2x + 5y = b
-2(6) + 5(4) = b
-12 + 20 = b
8 = b
Rewrite the original equation substituting the new b for the original -15
-2x + 5y = 8
Answer:
Step-by-step explanation:
The incenter of a triangle can be defined as the intersection of three angle bisectors that bisect all angles of the triangle.
By definition, an angle bisector divides an angle into two equal smaller angles.
Therefore:
What we're given:
The sum of the interior angles of a triangle always add up to be 180 degrees. Since these six angles make up the total sum of the interior angles, we have the following equation:
Substituting given values:
Since ,

In this question you are just figuring out 45% of 2400. To do this, you can halve 2400 to get 1200 which is 50%. Then, if you divide 2400 by 10 to get 240, and then divide by 2 to get 120, that is 5%. You can then just do 1200 - 120 = £1080, which is your answer
Answer: A
5.64-4.44 = 1.20
6.84-5.64 = 1.20
8.04-6.04 = 1.20
Each additional two hours adds $1.20 to the rental, so a slope of $0.60 per hour. That's the incremental cost per hour.
Two hours costs $4.44 so zero hours costs 4.44-1.20=$3.24. That's the y intercept, representing a fixed fee for every rental.
