Isosceles trapezoid ABCD has legs If AB = 6y – 3, BC = 4y – 5, and CD = 7y – 18, find the value of y

Mathematics

Answer:

The value of y is y=15

Step-by-step explanation:

We have:

AB = 6y – 3, BC = 4y – 5, and CD = 7y – 18

We define the isosceles trapezoid as it has two opposites parallel, the two other opposites legs are equal and also the diagonals are equal.

Here AB = CD

6y-3 = 7y-18

Combine the like terms:

18-3 = 7y-6y

15 = y

It means the value of y is  y=15....

~Offering 10 points please help ~
Musya8 [376]
Let's see if this is better
1: Substitute 0 for x in the equation → y = f(0) = a^0 = 1
    Therefore (0, 1) is a point on the graph

2: Substitute 1 for x in the equation → y = f(1) = a^1 = a
    Therefore (1, a) is a point on the graph

3: y = f(x) = a^x is an exponential function which has a horizontal asymptote of y = 0 (equation for the x - axis) ... The reason it is above the x-axis is because there is no negative coefficient on "a" to reflect it below the x-axis
