Answer:

3, -1

6,-4

IDK about the third vertices, you didn't give the original coordinates!

Step-by-step explanation:

180 degree rotation= (x,y) to (-x,-y)

3,1 goes to -3,-1

6,4 goes to -6, -4

IDK about the third vertice, you didn't mention it.

Reflection over y-axis= (x,y) to (-x,y)

-3, -1 goes to 3, -1

-6,-4 goes to 6,-4

hope this helps!

Brainliest?

have a good day!

Blake and James are planning to go on a trip. Blake already has some money saved. She earns $96 more by working overtime. James
rosijanka [135]

Blake saved \bold{\$ 433.80}

Option - A

<u>SOLUTION: </u>

Given, Blake and James are planning to go on a trip.  

Blake already has some money saved.  

Let the amount saved by Blake be \$ n.

She earns \$96 more by working overtime.  

Then, total amount by Blake =\$(n+96)

James has \$ 53 more than 4 times the amount of money that Blake has saved.  

Then, total amount by James will be \$ 53+4 \times \$ n=\$(4 n+53)

If they have \$2,318 in all, we have to find how much money had Blake originally saved

Now, total amount = \$2318

\begin{array}{l}{\rightarrow \text { Amount by Blake }+\text { amount by James }=2318} \\\\ {\rightarrow \mathrm{n}+96+4 \mathrm{n}+53=2318 \rightarrow 5 \mathrm{n}+149=2318 \rightarrow 5 \mathrm{n}=2318-149 \rightarrow 5 \mathrm{n}=2169 \rightarrow \mathrm{n}=433.8}\end{array}

In a competative exam of 40 questions plus three months is awarded for a correct answer and minus one for every correct answer t
Alex Ar [27]

Answer:

76

Step-by-step explanation:

n a competitive exam of 40 questions, +3 is awarded for a correct answer and -1 for every wrong answer. Find the total score if a student had 11 wrong answers in his attempt of all questions.

Answers gotten wrong = 11

answers gotten right = 40 - 11 = 29

total score = (point for correct answer x number of correct answer) +  (point for wrong answer x number of wrong answer)

(+3 x 29) + (-1 x 11) = 76

This table shows the relationship of the total number of pieces of fruit to the number of bananas.
ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is \dfrac{6}{5} not equivalent to \dfrac{3}{2}.

Solution:

If a, b, c are real numbers, then

\dfrac{a}{b}=\dfrac{a\times c}{b\times c}

The given fraction is \dfrac{3}{2}. It can be written as:

\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be \dfrac{6}{4}, not \dfrac{6}{5}.

Therefore, the correct option is A.
