The vertices of the image of GHJK after a translation are given. Choose the vector that describes the translation.
Lady_Fox [76]

Answer:

Option B

Step-by-step explanation:

Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,

From the graph attached,

Coordinates of G → (-5, 5)

Coordinates of the image point G' after the translation → G'(-5, 5)

Let the point G is translated 'a' units to the right and 'b' units down,

Rule for this translation,

G(x, y) → G'(x + a, y - a)

By this rule,

G(-5, 5) → G'(-5 + a, 5 - a)

-5 + a = -5 ⇒ a = 0

5 - a = 5 ⇒ a = 0

Therefore, vector that defines the translation will be,

<0, 0>

Option B is the the correct option.

Solve x2 - 8x + 15 &lt;0.
Stels [109]

Answer:

<h2> x<3 and x<5</h2>

Step-by-step explanation:

Given the quadratic inequality x² - 8x + 15 <0, to get the solution set for the inequality, the following steps must be followed;

Step 1: Factorize the quadratic expression

x² - 8x + 15 <0

x² - 3x - 5x + 15 <0

x(x - 3) - 5(x - 3)  <0

(x -3)(x -5)< 0

x -3<0 and x -5<0

x< 3 and x< 5

Therefore, the solution set for the quadratic inequality are x<3 and x<5

My checkerboard is 16 inches long by 16 inches wide. There are 64 playing
Zolol [24]
I’m not too sure but i think The area of one is 4 inches. There are 8 squares on each side, so when finding the area of the board, you get 64. The checkerboard is 16 inches long, and there are 8 squares, so it is approximately 2 inches long. To find area, you multiply length by width. Since they are squares, it would be 2*2, which leads you to the answer of 4. Hope this helps!
