Answer:
y = -1/13x + 1 3/13
Step-by-step explanation:
y = 13x + 2
Perpendicular
y = -1/13x + b
Finding b:
1 = -1/13 * 3 + b
1 = -3/13 + b
1 3/13 = b
y = -1/13x + 1 3/13

D. 48 she must rent 48 in order to receive the cash prize
Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
Answer:

Step-by-step explanation:
Let's set up a proportion using the following setup.

We know 30 buses can carry 1,500 people.

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.


Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

5 buses can carry 250 people.
