Complete the function for this graph:

Answers

Answer:

The equation is:

f(x) = Ix + 3I - 2

Step-by-step explanation:

For a function like:

f(x) = Ix - kI + c

k is the x-value where the vertex is, and c is the y-value where the vertex is.

In the graph we can see that the vertex is in the point (-3, -2)

then:

x-value = -3 = k

y-value = -2 = c

Replacing those in the equation for the function:

f(x) = Ix - (-3)I - 2

f(x) = Ix + 3I - 2

Rhombus L M N O is shown. Diagonals are drawn from point L to point N and from point M to point O and intersect at point P. The length of L M is 3 x minus 3 and the length of M N is x + 7. What is the perimeter of rhombus LMNO? 20 units 24 units 40 units 48 units

Answers

Answer:

48units

Step-by-step explanation:

Find the diagram of the rhombus attached

From the diagram, LM = MN

Hence;

3x - 3 = x + 7

Find x

Add 3 to both sides

3x - 3 + 3 = x + 7 + 3

3x = x + 10

3x - x = 10

2x = 10

x = 10/2

x = 5

LM= 3x - 3

LM = 3(5) - 3

LM = 12

Since LM = MN, then MN = 12

Since all the sides of the rhombus are equal then;

Perimeter of the rhombus = LM + MN + NO + OL

Perimeter of the rhombus = 12 + 12 +1 2 + 12

Perimeter of the rhombus = 48units

Answer:

48 Units is the answer

Answers

Answer:

oval, triangle

hope it helped you ☺

The cross sections of the cone shown can be circle, oval, parabola and triangle.

What is Cross Section?

Cross section of a figure or shape can be defined as a plane intersecting with the figure. The resulting shape formed in the intersection part is termed as cross section.

Given shape is a cone.

When a cone is intersected vertically, then the cross section formed is triangle.

When the cone is intersected through the straight horizontal line, we get the cross section as circle.

We will get an oval shape when the cone is intersected with the plane with a given slant by not touching the base.

A parabola shape is formed when a slant plane intersects by touching the base

Hence the cross sections of the given cone are circle, oval, parabola and triangle.

Find the equation parallel to y = -x - 5 and passing through (-3, -3)

Answers

Answer:

y = -x - 6

Step-by-step explanation:

If it's parallel, then it means that the slope will remain the same. The slope is

-1.

To find the y-intercept, you need to plug the coordinates into the equation,

y = -1x + b

-3 = -1(-3) + b

-3 = 3 +b

-6 = b

The equation is y = -x - 6
