X = 47 + 9y
xy = 1860
y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0
> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12
12y = 1860
y = 155
integers are 12 and 155
The probability of rolling an even number is three times (2,4,6) and the probability of rolling a number less than 5 is 4 times (1,2,3,4)
Not sure if I'm right or not but I hope this helps :)
Answer:
1. k=1, b=1
2. k=-1, b=-0.5
Step-by-step explanation:
Answer:
hope this is helpful.
putting values of X and y in the equation
Answer is <em><u>12</u></em>
All you have to do is divide the number by the denominator which is 8. So 510 divided by 8.
Which will give you 63.75.
Then you times it by the numerator which is 3 so 63.75 x 3
And you are left with £191.25 which is 3/8 of 510
