Y equals x2 plus 8x plus 15?
y = x2 + 8x + 15 = (x + 3)(x + 5). When y = 0, one or other of the two factors must equal zero; that is, x = -3 or -5, when y = 0.
What are x and y if 5 x y 40 are in a Geometric Progression?
For Geometric Progression #1 = a = 5 #2 = ar = x #3 = ar^2 = y #4 = ar^3 = 40 We need to find 'r' To do this ,divide #4 by #1 , hence ar^3 / a = 40 / 5 Hence r^3 = 8 (Notice the 'a' cancels down to leave 'r^3' Cube root both sides Hence r = 2 When r = 2 #2 = ar = 5 X 2 = 10 = x #3 = ar%2 - 5 x 2^2 = 5 x 4 = 20 = y So the geometric progression is 5,x,y,40 = 5,10,20,40
3 times the sum of a number and 5?
X more than y equa 6 times y
What is the 118th sequence in y-r-r-y-r-r-y-r-r-y-r-r-y-r-r?
It is y. Every third letter is r, immediately followed by y, and since 117 is divisible by 3, it is r. Therefore, 118 is y.
If r equals 5 z then 15 z equals 3 y then r equals?

What is 3 plus y times 5 plus y?
(3+y)(5+y) 3*5 + 3*y + y*5 + y*y 15 + 3y + 5y + y215 + 8y + y2y2 + 8y + 15
Y divided by 5 equals 3?
Y = 15 15 divided by 5 = 3
What is the inverse of 15-8times x divided by 3?
y = 15 - 8x/3 y - 15 = -8x/3 15 - y = 8x/3 x = 3/5(15 - y) and so x = 9 - 3y/5
What is the product of 5 and y plus 3?
if your question says 5(y+3) or 5 * (y+3) then its 5y+15
Factor 2xy -10x plus 3y -15?
2xy - 10x + 3y -15 = 2x(y - 5) + 3(y - 5) =(y - 5)(2x + 3)
80 equals 3 y plus 2 y plus 4 plus 1?
80 = 3 y + 2 y + 4 + 1 80 = 5 y + 5 80 - 5 = 5 y 75 = 5 y 15 = y So Y is 15
3(4y+5))=25?
3(4y+5) = 25 3 . 4y + 3 . 5 = 25 12 y + 15 = 25 12 y = 25 - 15 12 y = 10 y = 12:10 = 1.2
What is the factor of y-2y-15?
If that's y2, the answer is (y - 5)(y + 3)
What is the cube root of y to the 15th power?
Using the symbol "^" for powers: (y^15)^(1/3) = y^(15 times 1/3) = y^5.
What is the answere to 1 over 3 minus 1over 5?
1/3 - 1/5 = 5/15 - 3/15 = 2/15. For any pair of reciprocals, 1/x and 1/y, 1/x - 1/y = (y - x)/xy.
What is the x and y intercept of the line y equals -5x-15?
