Answer

:Reflected along x axis

Translated 7 units to the righ

A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.

Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).

If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)

If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:

It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)

It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Hopefully this helped, if not HMU and I will get you a better answer! :)

Can i get brainliest plz, im trying to unpgrade my rank!

Alright, I am hoping this is an flvs question, and that it comes from the quiz.

I came to this question because I needed help on it, but now I understand it, so im gonna help others :)

For Part A, the answer would be reflected on the x axis, translated 7 units to the right. This is true because by only reflecting it, the figure would not be on the exact spot. We have to translate it to the right.

For part B, the simple answer is that they are NOT congruent. As shown, they have been translated and moved, so in conclusion, they are not congruent. PLS MARK BRAINLIEST, not trying to be mean or anything, but I need it way more than the other person if you look at our ranks.

Answer:

126 units²

Step-by-step explanation:

Draw 5 vertical lines BR, CQ, EO, GM, HL and we will have 4 trapezoids and 2 rectangles.

Trapezoid ABRS ≅ trapezoid IHLK

Trapezoid DEOP ≅ trapezoid FEON

Rectangle BCQR ≅ rectangle GHLM

Area of trapezoid is [tex]\frac{b_{1} +b_{2} }{2}h[/tex]

Area of rectangle is [tex]lw[/tex]  

The total area of the figure is: ( 2 × [tex]A_{ABRS}[/tex] + 2 × [tex]A_{BCQR}[/tex] + 2 × [tex]A_{DEOP}[/tex] )

In trapezoid ABRS: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 8 and h = 3 ⇒

2 × [tex]A_{ABRS}[/tex] = 2 × [3(6 + 8) ÷ 2] = 42 units²

In rectangle BCQR: l = 6 and w = 3 ⇒

2 × [tex]A_{BCQR}[/tex] = 2 × (6 × 3) = 36 units²

In trapezoid DEOP: [tex]b_{1}[/tex] = 6, [tex]b_{2}[/tex] = 10 and h = 3 ⇒

2 × [tex]A_{DEOP}[/tex] = 2 × [3(6 + 10) ÷ 2] = 48 units²  

[tex]A_{total}[/tex] = 42 + 36 + 48 = 126 units²  

Answer:

there is an additional oxygen in the product

The probability helps us to know the chances of an event occurring. The number of possible outcomes When Denato pulls a pen from the bag is 29.

The probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that the bag has 8 red pens, 7 blue pens, and 14 black pens. Therefore, if Denato will pull a pen from the bag the number of possibilities will be the sum of all the number of pens.

Number of Possibilities = 8 + 7 + 14 = 29

Thus, the number of possible outcomes When Denato pulls a pen from the bag is 29.

b) The property states that ab is equivalent to b a

Step-by-step explanation:

Commutative property:-

the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.

Let 'a' and 'b' be the two integers , then  ab = b a

Example:-

   .    1 X 2 = 2 X 1 = 2

  .    12 X 5 = 5 X 12 = 60

Answer:5/4

Step-by-step explanation:

Area = length* width

5/8 = 1/2 * width

Width = 5/4

Answer:

5/4 miles.

Step-by-step explanation:

Width = area / length

=  5/8 / 1/2

= 5/8 * 2

= 10/8

= 5/4 miles.

Answer:

2/6 or 33.33%

Explanation:

There are 6 numbers all together and 2 of them are 20$.As a fraction this would look like 2/6. 2/6 is also 33.33% of the wallet and its also the probability of pulling out a $20 bill

The probability that they are both $20 bill when There are two 20's, one 10, two 5's, and one 1 is to be considered as the 33.33%.

Since

You randomly choose two bills from your wallet.

And, there is 6 numbers

So, the probability is

[tex]= 2\div 6[/tex]

= 33.33%

Hence, The probability that they are both $20 bill when There are two 20's, one 10, two 5's, and one 1 is to be considered as the 33.33%.

Answer:

0.075, 75%, 3/4

Step-by-step explanation:

Convert everything to decimals for ease of comparison.

0.075 ⇒ Leave as is.

75% ⇒ Divide by 100 to make it a decimal number.

= [tex]\frac{75}{100}[/tex]

= 0.75

3/4 ⇒ Divide the numerator by the denominator.

= 0.75

Put them in order of place value:

Units  tenths   hundredths  thousandths

0.          0                7                    5

0.          7                5

0.          7                5

By comparing the numbers, we can put them in the following order from least to greatest:

0.075, 75%, 3/4

Answer:

Decimal: 0.80      Reduced fraction: [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Take 80% and move the decimal two place values to the left.

This makes 0.80              (The decimal point is where the percent sign is.)

0.80 is [tex]\frac{8}{10}[/tex]  because the 8 is in the tenths place value.

[tex]\frac{8}{10}[/tex] can be simplified by dividing both the numerator and the denominator by 2.

[tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

Answer:

In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables). The case of one explanatory variable is called simple linear regression. For more than one explanatory variable, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.

Answer:

Step-by-step explanation:

The interior angles of a triangle add to 180°:a + b + c = 180°

Angles c and d make a straight angle, which is 180°:d + c = 180°

So d + c equals a + b + c:d + c = a + b + c.

Subtract c from both sides:d = a + b.
