Answer: If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.
Step-by-step explanation:
- We know that when a complex number
is a root of a polynomial with degree 'n' , then the conjugate of the complex number (
) is also a root of the same polynomial.
Given: 7+5i is a zero of a polynomial function of degree 5 with coefficients
Here, 7+5i is a complex number.
So, it conjugate (
) is also a zero of a polynomial function.
Hence, if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.
Answer:
I think that's 25 though I have no assurance
The value of y would decrease if x increases and the sum stays the same.
<h3>Option D</h3><h3>The simplified version of 7x − 4(x − 8) = 56 is 3x + 32 = 56</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
Use distributive property to simplify the expression
By distributive property,
a(b + c) = ab + ac
Therefore,
Combine the like terms : 7x - 4x = 3x
Therefore,
Thus option D is correct
The answers are:
a) 64x - 24
b) 19y
