Answers

Answer: y=2/3x+3


*Remember the original equation in slope-intercept form*

y=mx+b

*label that with what each letter stands for*

m=slope/rate of change
x=variable
b=y-intercept

*Substitute this information into the equation

y=2/3x+3

Pentagon VWXYZ is congruent to pentagon V" W" X" Y" Z" . Which sequence of transformations could have been used to transform pentagon VWXYZ to produce pentagon V" W" X" Y" Z"?A. Pentagon VWXYZ was reflected across the y-axis and then reflected across the x-axis.
B. Pentagon VWXYZ was reflected across the y-axis and then translated 2 units left and 4 units down.
C. Pentagon VWXYZ was rotated 90° counterclockwise around the origin and reflected across the y-axis.
D. Pentagon VWXYZ was translated 7 units down and then reflected across the y-axis.

Answers

The right answer for the question that is being asked and shown above is that: "C. Pentagon VWXYZ was rotated 90° counterclockwise around the origin and reflected across the y-axis." This is the sequence of transformations could have been used to transform pentagon VWXYZ to produce pentagon V" W" X" Y" Z"

Final answer:

Given that Pentagon VWXYZ is congruent to Pentagon V"W"X"Y"Z", the feasible sequence of transformations could be - reflecting VWXYZ across the y-axis and then translating it 2 units left and 4 units down.

Explanation:

In geometry, a sequence of transformations includes operations like translations (moving a given distance in a certain direction), reflections (flipping a shape over a line), and rotations (turning a shape around a point). Given that Pentagon VWXYZ is congruent to Pentagon V"W"X"Y"Z", the transformation should preserve the shape and size of the object.

The options suggest transformations including reflections, translations, and rotations. Seeing as there is no information about changes in orientation within their individual planes, we can disregard rotations; so, among the given choices, option B – Pentagon VWXYZ was reflected across the y-axis and then translated 2 units left and 4 units down, could be a viable sequence of transformations. However, these options are based only on the information given and real solutions may vary if other transformation details were provided.

How to solve mp-5p when m=-4 and p=2

Answers

You can substitute in the values. So m=-4 so put that in instead of m. And p=2 so put that in instead of p.
The problem is then (-4)(2)-5(2). Simplify to -8-10 And your final answer is -18. Wasnt aware you could edit these after you made them haha. I did correct my math in my comments riaght after the post. Sorry about that guys ^.^
so everyone knows, xy means x times y, not the digits themselves

so mp-5p
subsitute -4 for m and 2 for p
(-4)(2)-[(5)(2)]
-8-[10]
-18

What is 3/8 divided by 9/16? Please explain and show work.

Answers

To divide a fraction by a fraction you multiply by the reciprocal. That means that you turn the second fraction upside-down, and multiply.
So if you have 3/8 divided by 9/16, you will end up with
3/8 * 16/9
So now you can simplify diagonally, and it becomes 1/1 * 2/3, which is the same as 1 * 2/3.  The next step would be just to multiply fractions like normal, but since we know that any number times 1 is the number, the answer is 2/3
ANSWER: 2/3
Hope this helped, and feel free to ask more questions if you need!!(:
step1:keep
        that mean you keep 3/8 normal
step2:change
         that mean you change ÷ to ×
         3/8×
step3:flip
         that mean you flip the second number
         9/16 change to 16/9
         3/8×16/9=48/72
so the answer is 48/72
remember there is 3 step:keep 
                                     change
                                     flip

A number (x) increased by 6 and then the sum is doubled

Answers

The number 10 increased by 6 and then doubled equals 32.

To express the situation where a number (x) is increased by 6 and then the sum is doubled, we can write it as:

2(x + 6)

In this expression, (x + 6) represents the number increased by 6, and then multiplying the sum by 2 doubles the result.

For example, if the number x is 10, then the expression would be:

2(10 + 6) = 2(16) = 32

So, in this case, the number 10 increased by 6 and then doubled equals 32.
