-2(x + 5) = 2  |use distributive property: a(b + c) = ab + ac

-2x - 10 = 2    |add 10 to both sides

-2x = 12    |divide both sides by (-2)

x = -6

If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is _.
defon

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 z=a+ib is a root of a polynomial with degree 'n' , then the conjugate of the complex number (\overline{z}=a-ib) 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 (\overline{7+5i}=7-5i) 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>.

What does it mean if the x-coordinate in an ordered pair is zero? What if the y-coordinate is zero? Both? Explain.
Harman [31]
If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.

for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^

or if it was just (0,0) it would be a dot in the middle
