A figure is reflected in the x-axis. How will the coordinates change?
A. The x-coordinates will stay the same.
B The x-coordinates will change sign.
C The y-coordinates will stay the same.
D The y-coordinates will change sign.
Answer: The y-coodinates will change sign.
Step-by-step explanation: This is because it is being flipped over the x line. If you have the coordinate (2,3) then when you flip it you will end up with (2,-3)
if a van traveled 150 miles in 3 hours, how many miles could the van travel in 6 hours?
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

Which of expressions illustrates the associative property?
ab + bc
a ( b + c ) = ab + bc
a ( b + c ) = (a + b ) + c
a + b + c = c + b + a
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.
The Empire State Building is just over 1,450 feet tall. In anticipation of visiting this
landmark on your vacation, you create a model of it using blocks.
a) Suppose you are making a model where one block represents 2 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)
b) Suppose you are making a model where one block represents 5 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)
c) Look at the scale factor from parts a and b. Do they represent a reduction or an enlargement of the Empire State Building? How do you know? (2 points)
d) Use your knowledge of scale drawings and image sizes to fill in the missing
information in the table. (3 points)
Model requiring 525 block and 290 blocks
What is scale factor ?Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii.
a) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.
Number of blocks=1,450 feet * (1 block/2 feet)
Number of blocks = 725 blocks
Therefore, you would use a model requiring 725 blocks.
The scale factor for the model is 1 block per two feet.
b) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 5 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 5.
Number of blocks=1,450 feet * (1 block/5 feet)
Number of blocks = 290 blocks
Therefore, you would use a model requiring 290 blocks.
The scale factor for the model is 1 block per five feet.

What kind of symmetry does this figure have?
point
line
both line and point
neither
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.

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
