Point C is the image of C (-4, -2) under a reflection across the y-axis.

What are the coordinates of C?

Answers

Answer 1

Answer: (4,-2)

Step-by-step explanation:

if you reflect a point across the y-axis, that point must be on the same horizontal line then to the pre-mage meaning the y coordinates must remain the same. From their we want the points on both sides of the t-axis to have the same distance. x and -x have the same distance from 0. Therefore this means you will need to take the opposite of X.

So point (x,y) being reflecting over the y-axis will give us (-x,y).

(x , y)--->(-x,y) mean you have (-4,-2)---->(4,-2)

Answer:

2x+15=33

Step-by-step explanation:

Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.

Since he started doing  15 sit-ups on the first day, the total number of sit-ups

after x days would be 2n+15.

Since he did a total of 33 sit ups today, then 2n+15=33

What are some examples of recursion in real life, such as things you can write a recursive equation for? (for example, fern leaves are an example of a geometric sequence, and the distance from the ground on stairs is an example of an arithmetic sequence)

Answers

Answer: In programming terms, recursion happens when a function calls itself. If you have a problem that is too complex, you can use recursion to break it down into simpler blocks. You do this in real life all the time. Imagine you have a whole box full of $100 bills and you need to count how much money you have.

Answers

Answer:

line and point

Step-by-step explanation:

The kind of symmetry the figure given above posses is a line and point symmetry.

What is point symmetry?

A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.

Given that;

The objects looks the same when viewed from opposite directions.

We know that;

A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.

Therefore, the figure given above has both point and line Symmetry.

if a van traveled 150 miles in 3 hours, how many miles could the van travel in 6 hours?

Answers

Answer:

300 because if he traveled 150 in 3 to find six just multiply by 2

Answer:

The van traveled 300 miles in 6 hours.

Step-by-step explanation:

150 divided by 3 = 50

So each hour the van traveled 50 miles.

50 x 6 = 300

What value of c is a solution to this equation?
–5=–3(c–2)–8

Answers

Answer:c=1

Step-by-step explanation:Step 1: Simplify both sides of the equation.

−5=−3(c−2)−8

−5=(−3)(c)+(−3)(−2)+−8(Distribute)

−5=−3c+6+−8

−5=(−3c)+(6+−8)(Combine Like Terms)

−5=−3c+−2

−5=−3c−2

Step 2: Flip the equation.

−3c−2=−5

Step 3: Add 2 to both sides.

−3c−2+2=−5+2

−3c=−3

Step 4: Divide both sides by -3.

Which of expressions illustrates the associative property?

a + b + c = c + b + a

Answers

Answer:

c)   a ( b + c ) = (a + b ) + c

Step-by-step explanation:

The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

Tom has a part-time job. On Wednesday, Tom earned $20.50, and on
Thursday he earned $36.21. On Friday, Tom earned twice as much as he
did on Wednesday. How much did Tom earn altogether for the three days?

Answers

Answer:

97.71

Step-by-step explanation:

Answer: $20.50 + $36.21

Step-by-step explanation:

$20.50 (Wednesday) + $36.21 (Thursday) = $56.71     Since Tom is getting twice as much he did on Wednesday ($20.50), we'll be doing this: $20.50 x 2 (which equals 41 or $41.00) and add it to $56.71

$56.71 + $41.00 = $97.71    So, this means that Tom earned $97.71 altogether for three days
