Answer:
Equation: 3x + 7 = 16
Unknown Number: 3
Step-by-step explanation:
You must first develop an equation representing this problem:
3x + 7 = 16
Then, you can solve for the unknown number.
3x + 7 = 16
3x = 9
x = 3
Answer:
18
Step-by-step explanation:
Evaluate (2 x^2)/y + 16 x^0 where x = 2 and y = 4:
16 x^0 + (2 x^2)/y = 16×2^0 + (2×2^2)/4
2/4 = 2/(2×2) = 1/2:
16×2^0 + 2^2/2
Combine powers. 2^2/2 = 2^(2 - 1):
16×2^0 + 2^(2 - 1)
2 - 1 = 1:
16×2^0 + 2
2^0 = 1:
16×1 + 2
16 + 2 = 18:
Answer: 18
Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
