(x - a)^2 + (y - b)^2 = (y - d)^2

x^2 - 2ax + a^2 + y^2 - 2by + b^2 = y^2 - 2dy + d^2 

Subtract y^2 from both sides... 

x^2 - 2ax + a^2 - 2by + b^2 = -2dy + d^2 

Now I would just substitute in the the values (a = -4, b = 17/8, d = 15/8)... 

x^2 - 2(-4)x + (-4)^2 - 2(17/8)y + (17/8)^2 = -2(15/8)y + (15/8)^2 

Simplify... 

x^2 + 8x + 16 - (17/4)y + 289/64 = -(15/4)y + 225/64 

Add (17/4)y to both sides... 

x^2 + 8x + 16 + 289/64 = (2/4)y + 225/64 

x^2 + 8x + 16 + 289/64 = (1/2)y + 225/64 

Subtract 225/64 from both sides... 

x^2 + 8x + 16 + 1 = (1/2)y 

x^2 + 8x + 17 = (1/2)y 

Multiply both sides by 2... 

2x^2 + 16x + 34 = y 

...which is equal to equation D.

five times the larger of two consecutive odd integers is equal to one more than eight times the smaller. What is the larger inte

Margarita [4]

The formula to find two consecutive odd integers is x + (x+2)
5(x+2) = 1 + 8(x)
5x + 10= 1 + 8x
10= 1 + 3x
9=3x
x = 3
Answer : the larger integer is 5(3+2) which is 25

Kahlil is recording a beat for a song that he is working on he wants the length of the beat to be more than 17 seconds long. His

Svet_ta [14]

In the problem, the length of the beat is take by variable T.

According to problem,

Kahlil wants, "the length of the beat to be more than 17 seconds long".

We took length of beat by variable T.

Therefore, the length of the beat to be more than 17 seconds long could be rephrase as

" T is more than 17".

And in inequality form we can write it as

T>17.
