Answer:

t = 100 - 5n : rule for amount of money left.

You will have $45 left after using downtown parking 11 times.

Explanation:

The equation for an arithmetic sequence in this case is t = a + dn.

a is the initial value, d is the rate of change, and n is the independent variable.

t is the dependent variable.

In this context, a is the starting budget for parking, d is the amount parking costs each time, n is the number of times you use the parking and t is the amount of money left after each time you use the parking.

Substitute the known values from the problem into the equation.

t = a + dn

t = 100 + (-5)n <= the rate of change is -5 because it's decreasing

t = 100 - 5n

To find the amount of money left after 11 times using downtown parking, substitute n for 11.

t = 100 - 5n

t = 100 - 5(11)

t = 100 - 55

t = 45

You will have $45 left after 11 times parking downtown.

BD is the angle bisector of ZABC

Thepotemich [5.8K]

Answer:

x = 7, y = 2

Explanation:

Two triangles are said to be congruent if all three sides and three angles of one triangle is equal to three sides and three angles of the other triangle.

From the question:

BD ≅ BD (reflexive property of equality)

Since BD is the angle bisector of ∠ABC, hence ∠ABD = ∠CBD

∠ABD = 2x + y, ∠CBD = 14 + y. Therefore:

2x + y = 14 + y

2x = 14 + y - y

2x = 14

x = 14 / 2

x = 7

Also, ∠BAD = ∠BCD = 90° (right angled triangle)

Since ∠BAD = ∠BCD, BD ≅ BD and ∠ABD = ∠CBD, therefore ΔABD is congruent to ΔCBD by angle-angle-side congruence theorem.

The angle-angle-side congruence theorem states that if two angles and one side of one triangle is equal to two angles and one side of another triangle the both triangles are congruent.

ΔABD is congruent to ΔCBD, therefore AD = CD

5x - y = x + 13y

13y + y = 5x - x

14y = 4x

14y = 4(7)

y = 4(7) / 14

y = 2
