Answer:
x/y= −3 => x= −3y
x²/y²+y²/x²=y²/x²
Step-by-step explanation:
Evaluate xy, then set it equal to −3.
x=−3y
Evaluate x²/y²+y²/x².
y²/x²
2 hours! because, 12 plus 3 is 15 & 15 times 2 equals 30
Answer:
wha tis the qeustion
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
4( x + 1.5)^2 + 0
Discussion:
4x^2 + 12x + 9 = => factor "4" from first 2 terms
4 (x^2 + 3x) + 9 = => complete the square, add\subtract (1.5)^2
4(x^2 + 3x + (1.5)^2) - 4 (1.5)^2 + 9 =
4 ( x + 1.5)^2 + ( 9 - 4(1.5)^2) = => as (1.5)^2 = 2.25
4 ( x + 1.5)^2 + ( 9 - 4(2.25)) = => as 4 ( 2.25) = 9
4 ( x+ 1.5)^2 + 0
Thank you,
MrB
Answer:
46
Step-by-step explanation:
You need just substitute values of x and y, and calculate.
24x - 13y = 24*3 - 13*2 = 72 - 26 = 46
