Answer:
18 and 335
Step-by-step explanation:
y = 18x + 11
x * y = 6030
x * (18x + 11) = 6030
18x^2 + 11x = 6030
18x^2 + 11x - 6030 = 0
(18x + 335)(x - 18) = 0
18x + 335 = 0 x - 18 = 0
18x = -335 x = 18
x = -335/18
x is gonna have to be a positive number...so x = 18
y = 18x + 11
y = 18(18) + 11
y = 324 + 11
y = 335
so ur numbers are 18 and 335
Are those all your options? the answer would be 3x+10= 28 but you dont have it as a multiple choice.
Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
= (1 - tan^2 (x)) / (1 + tan^2 (x))
= (1 - (-4/3)^2) / (1 + (-4/3)^2)
= (1 - (16/9)) / (1 + (16/9))
= (9 - 16) / (9 + 16) [By multiplying numerator and denominator with 9]
= (-7) / (25)
= -7/25
They are stupid. correlation is always between -1 and +1
