The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
First positive number (x) = x
Second positive number (y) = x+3
Product: 180 = x · y
180 = x · (x + 3)
180 = x² + 3x
0 = x² + 3x - 180
0 = (x + 15)(x - 12)
0 = x + 15, 0 = x - 12
x = -15, x = 12
x = -15 is NOT a positive number so it can be disregarded.
Answer: 12
Answer:
{x\ x e U and x has a negative square root} is an empty set.
Step-by-step explanation:
If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.
Answer:
2813 English books
Step-by-step explanation:
Hindi books are 42% of 4850
42 ÷ 100 = 0.42
0.42 × 4850 = 2037 Hindi books
number of English books = total number of Hindi and English books - number of hindi books
4850 - 2037 = 2813 English books
Answer:
h = -2.5
Step-by-step explanation:
- Apply the distributed property: -6h + 8h + 6 = 1
- Combine like terms: 2h + 6 = 1
- Subtract 6 from each side, so it now looks like this: 2h = -5
- Divide each side by 2 to cancel out the 2 next to h. It should now look like this: h = -2.5
I hope this helps!
