In this question we will be using Associative Law of Addition which is as follows:

The Law that says you can swap numbers around and still get the same answer when you add.

a+b =b+a

where a and b are addends.

Using this law, we can clearly see that order of addends does not matter at all in addition.

Now adding -5+6, we get 6-5 which is equal to 1

Answer is 1

In this question we will be using Commutative Law of Addition which is as follows:

The Law that says you can swap numbers around and still get the same answer when you add.

a+b =b+a

where a and b are addends.

Using this law, we can clearly see that order of addends does not matter at all in addition.

Now adding -5+6, we get 6-5 which is equal to 1

nalin [4]

Easy question.

So, the slope is -x and the y-intercept is at -4.

y = -x - 4

Use this equation and you will find:

y = -2 - 4

y = -6

Answer: (2, -6)

Topic : Geometry <br> Can someone tell me what Conic sections is in 4-8 sentences ?
krok68 [10]

Conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse. The circle is a special case of the ellipse, previously called the fourth type. Planes that pass through the vertex of the cone will intersect the cone in a point, a line or a pair of intersecting lines, called degenerate conics.

Part A
Anuta_ua [19.1K]

Answer:

Part A: There are 4 zeros of the polynomial function f(x)

Part B: The zeroes of the polynomial function f(x) are -4, -1, 0, 2 ⇒ C

Step-by-step explanation:

<em>The zeroes of a function are </em><em>the x-coordinates of the point of intersection between the graph of the function and the x-axis</em><em> (x-intercepts) which means </em><em>values of x at y = 0</em>

Part A:

In the given graph

∵ The graph of the function f(x) = -x^{4} - 3x³ + 6x² + 8x intersects the x-axis

   at 4 points

→ That means there are 4 values of x have y = 0

∴ The number of zeroes of the function is 4

∴ There are 4 zeros of the polynomial function f(x)

Part B:

∵ The graph intersects the x-axis at points (-4, 0), (-1, 0), (0, 0), (2, 0)

→ That means the values of x at y = 0 are -4, -1, 0, 2

∴ f(x) = 0 at x = -4, -1, 0, 2

∴ The zeroes of the polynomial function f(x) are -4, -1, 0, 2
