Answer:
25*3 or 25(3)
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
let the 2 digit number be ab then digit in unit place is 2 more than ten place
2 digit number is a a + 2 where b = a + 2.
Thus sum of digits = a + a + 2 = 2a + 2, then
ab + 3(2a + 2) = ba ← using place value of digits
10a + b + 6a + 6 = 10b + a, that is
16a + 6 + b = 10b + a ( subtract 10b + a from both sides
15a - 9b + 6 = 0 ← substitute b = a + 2
15a - 9(a + 2) + 6 = 0
15a - 9a - 18 + 6 = 0
6a - 12 = 0 ( add 12 to both sides )
6a = 12 ( divide both sides by 6 )
a = 2
Thus the number is 24
Answer: The two functions are
f(x) = sqrt(64x^2+64)
g(x) = -sqrt(64x^2+64)
Graphing these together forms a hyperbola
To get these two functions, we need to solve for y
y^2 - 64x^2 = 64
y^2 = 64x^2 + 64
y = sqrt(64x^2 + 64) or y = -sqrt(64x^2 + 64)
The last line is similar to how x^2 = 9 has two solutions (x = plus or minus 3)
