Answer:
<em>B. a = y - k/(x-h)² </em>
Step-by-step explanation:
Given the expression y = a (x-h)² + k
First make a the subject of the formula
Subtract k from both sides
y = a (x-h)² + k
y- k = a (x-h)² + k - k
y - k = a (x-h)²
Divide through by (x-h)²
y - k/(x-h)² = a
a = y - k/(x-h)²
Hence option B is correct
X=6

Answer: 33
Step-by-step explanation: you need to follow the rule of BODMAS so, in this expression the multiplication comes first which is 16×3 = 48 then you find what 9² is which equals to 9×9= 81 so 81 - 48 = 33.
Answer:
5
Step-by-step explanation:
(4+20+x)/3 = (y+16)/2
2(24+x) = 3(y+16)
48 + 2x = 3y + 48
2x = 3y
Since x and y are positive integers, they can't be 0. To satisfy 2x = 3y
We'll have to use LCM of 2 and 3, which is 6 (or a multiple of 6)
For the least value, we use 6
To make both sides 6,
x = 3 and y = 2
Hence x + y = 5
