Answer:

4x + 3y = 5

Step-by-step explanation:

Gradient = -9 -11/ 8 + 7

= -4/3

Equation of the line...

y = mx + c

y = -4/3(x + 7) + 11

Multiplying through by 3...

3y = -4x - 28 + 33

3y = -4x + 5

4x + 3y = 5

Find the measure of c. A. 136 B. 144 C. 123 D. 149
-BARSIC- [3]

Answer:

Option (D)

Step-by-step explanation:

Given quadrilateral in the circle is a cyclic quadrilateral.

By using the property of cyclic quadrilateral,

"Sum of each pair of opposite angles is 180°".

In the given cyclic quadrilateral,

d + 57° = 180°

d = 180 - 57

d = 123°

Similarly, c + 31° = 180°

c = 180° - 31°

c = 149°

Therefore, Option (D) will be the answer.

Can someone one help you will get that crown on you thing if it right
Tcecarenko [31]

Answer:

True

Step-by-step explanation:

When the value of the positive number is the same as the negative number, the sum is zero. The positive number and negative number cancel each other out or simplify. The sum of two negative integers is always negative. When two or more negative numbers are added together, the result or sum is always negative

Find the​ fourth-degree polynomial function with zeros 4​, -4, 4i ​, and -4i . Write the function in factored form.
Iteru [2.4K]

Given:

A fourth-degree polynomial function has zeros 4​, -4, 4i ​, and -4i .

To find:

The fourth-degree polynomial  function in factored form.

Solution:

The factor for of nth degree polynomial is:

P(x)=(x-a_1)(x-a_2)...(x-a_n)

Where, a_1,a_2,...,a_n are n zeros of the polynomial.

It is given that a fourth-degree polynomial function has zeros 4​, -4, 4i ​, and -4i. So, the factor form of given polynomial is:

P(x)=(x-4)(x-(-4))(x-4i)(x-(-4i))

P(x)=(x-4)(x+4)(x-4i)(x+4i)

P(x)=(x-4)(x+4)(x^2-(4i)^2)           [\because a^2-b^2=(a-b)(a+b)]

On further simplification, we get

P(x)=(x-4)(x+4)(x^2-4^2i^2)

P(x)=(x-4)(x+4)(x^2+16)                [\because i^2=-1]

Therefore, the required fourth degree polynomial is P(x)=(x-4)(x+4)(x^2+16).
