When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image?

1 answer:

7 0

When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another.

Emphasize the basic properties of translations:

1. Lines are taken to lines, and line segments to line segments of the same length (this property states that choice C is incorrect).

2. Angles are taken to angles of the same measure.

3. Parallel lines are taken to parallel lines and orientation of the figure remains the same (this property states that choice B is incorrect).

4. The image of a figure under a translation is always congruent to the preimage (this property states that choice A is incorrect).

Answer: correct choice is D (prove that using property 1 and definition of translation).

Answer:

Step-by-step explanation:

Assuming the triangle is right, use Pythagoras' identity to find N

The square on the hypotenuse is equat to the sum of the squares on the other 2 sides.

Here the hypotenuse = 73, thus

N² + 48² = 73², that is

N² + 2304 = 5329 ( subtract 2304 from both sides )

N² = 3025 ( take the square root of both sides )

N = $\sqrt{3025}$ = 55 → A

Determine whether the following sample may be biased explain

I would say the answer is D, since the sample only shows that customers on Mondays were surveyed, and says nothing about other customers on different days.

Look at the graph of a line and write its equation

Mice21 [21]

Answer:

y=-2/3x-1

Step-by-step explanation:

You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3

to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1

PLEEEEASE HELP!!!! WHO EVER IS BEST WILL BE BRAINLIEST!!!!!!!!!!!!!!!!

Answer:

No they will not reach their goal because they made $310 which is less than $400.

Step-by-step explanation:

Part A the inequality:

You want to make at least 400 or more on the fundraiser, so use greater that or equal to. I used h to represent holiday cards and w to represent wrapping paper.

$1.50h + 1.00w \geq 400$

Part B:

$1.50h + 1.00w \geq 400\\1.50(100)+1(160)\geq 400\\150+160\geq 400\\310\geq 410$

No they will not reach their goal because they made $310 which is less than $400.
