Answer:
The zeros of the polynomial are x = 7 or x = -11/2
Step-by-step explanation:
The zeros of a polynomial refers to the solution of the polynomial.
6x^2 + 19x -77
6x^2-14x+ 33x -77
2x(x-7) + 11(x-7)
= (2x + 11)(x-7)
2x + 11 = 0
x-7 = 0
2x = -11
x = -11/2 = -5.5
and x-7 = 0
x = 7
So the zeros of the polynomial are x = 7 or x = -11/2
Answer:
Step-by-step explanation:
I don't know if this is what you are looking for but, I would use substitution to solve what x and y are
6x+2y = 1
is the same as -6x-2y= -1 because if you multiply everything by -1 it will equal
6x+2y = 1
so now you have
6x+2y = 1
6x+2y = 1
I would set the equation equal to one variable and substitute.
6x+2y = 1 = 2y = 1 - 6x = y = (1/2) - (6x/2) = y = (1/2) - 3x
now plug in (1/2) - 3x in to one of the y's because they are the same equation
6x + (1/2) - 3x = 1
subtract 1/2
6x - 3x = 1/2
subtract the x's
3x = 1/2
now divide both sides by 3
x = (1/2)/ 3
x = 1/6
now that you know what x equals, plug that into the equation and find y
6(1/6) + 2y = 1
1 + 2y = 1
subtract 1
2y = 0
now divide to find y
y = 0/2
y = 0
so
x = 1/6 and y = 0
If the given expression is simplified we get c. 2x²y³ + 3y.
Explanation:
- The numerator has two terms while the denominator only has one term. We divide the numerator terms each separately with the denominator term.
- So 14x⁵y⁴ + 21x³y² / 7x³y becomes 14x⁵y⁴ / 7x³y + 21x³y² / 7x³y.
- The simplification of the first term; 14 / 7 = 2, x⁵ / x³ = x², y⁴/y = y³. So the first term is 2x²y³.
- The simplification of the second term; 21 / 7 = 3, x³ / x³ = 1, y² / y = y. So the second term is 3y.
- Adding both the terms we get 2x²y³ + 3y. This is the option c.
Answer: 3 * 10 ^3
Step-by-step explanation:
Divide the numbers
3.9 / 1.3
3
Subtract the powers of 10
10^5 / 10^2 = 10 ^ (5-2) = 10^3
The result is 3 * 10 ^3
