Answer:
p = 121
Step-by-step explanation:
inveresly proportional
pq² = k
find k the constant of proportionality
p is 16 when q is 11,
16 * 11² = k
k = 1,936
----------------------------
pq² = 1,936
determine p when q is equal to 4.
p * 4² = 1,936
16p = 1,936
p = 1,936/16
p = 121
Answer:
43
Step-by-step explanation:
All the even numbers have a factor of 2, so we can eliminate 56 and 34. 75 ends in a 5, so that cannot be a prime number (ending in 5 is a multiple of 5). The sum of the digits of 63 (6+3) is 9, and that is divisible by 3, so that number is also not prime. 43 is a prime number.
If you are solving for y, your answer is -1.
First, x=4 so plug in the 4 in every into every x.
Second, 4^2 is 16. 8(4) is 32.
Third, 16 - 32 + 15= -1
