Answer:

  translate 4 left and 3 up

Step-by-step explanation:

The value added to the x-coordinate is the translation to the right. Here, it is -4, so the translation is 4 units left.

The value added to the y-coordinate is the translation up. Here, it is +3, so the translation is 3 units up.

The rule effects a translation 4 units left and 3 units up.

Round your answer to the nearest tenth.

Answer:

The value of MB = 8.4

Step-by-step explanation:

We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.

Thus,

For the given triangle ΔJKL,

  • The point M is the centroid of the triangle.

We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.

In our case,

The median KB is split into two parts such that the longer part KM is 2 times the length of the smaller part MB.

i.e.

KM = 2 MB

Given KM = 16.8

so substitute KM = 16.8 in the equation KM = 2 MB

16.8 = 2 MB

MB = 16.8/2

MB = 8.4

Therefore, the value of MB = 8.4

3. Use the polynomial 12x^4 y^2 + 30x^3 y to answer the following questions?
barxatty [35]

Answer:

\huge\boxed{GCF:6x^3y}

\huge\boxed{Factored: 6x^3y(2x+5)}

Step-by-step explanation:

Look at both terms separately, and isolate each "part."

i.e. 12x^4y^2 becomes 12, x^4, y^2

So the problem becomes:

12, x^4, y^2 and

30, x^3, y^1

Then, find the GCF of each term,

30 and 12 - 6

x^4 and x^3 - x^3

y^2 and y^1 - y^1

Hope it helps :) and let me know if you want me to elaborate.

Write x2 - 12x + 8 in vertex form.
Marysya12 [62]

Answer:

The answer to this is: y = (x - 6)² - 28

Step-by-step explanation:

The first step is to make sure the coefficient in front of x² is 1. If it isn't, just divide the whole equation by the coefficient. In this case, you don't need to do any division because you just have x²

Group the first two terms involving x² and x:

(x² - 12x) + 8

Now complete the square as follows:

a. Take the coefficient in front of x --> -12

b. Halve it --> -6

c. Square it --> (-6)² = 36

d. Add this and subtract it

(x² - 12x + 36 - 36) + 8

Take the negative number outside the parentheses:

(x² - 12x + 36) - 36 + 8

(x² - 12x + 36) - 28

The part in parentheses is a perfect square so rewrite it as such. If you need help refer back to step b.

(x - 6)(x - 6) - 28

(x - 6)² - 28

P.S. Vertex form is:

(x - h)² + k

In that form, the vertex is (h, k). In your case, the vertex of the parabola would be (6, -28).

Answer:

y = (x - 6)² - 28
