Determine whether the dilation from figure A to Figure B is a reduction or enlargement ​

Answer: The answer is B

Step-by-step explanation:

Answer:

= 3

/3 + 5a/12 = 9/4

Answer:

m = -1

Step-by-step explanation:

3m + 6 = 5m + 8

-3m        -3m

6 = 2m + 8

-8           -8

-2 = 2m

divided by 2

-1 = 1m

m = -1

A figure with a rotation symmetry will look the same, when rotated. The figures with [tex]180^o[/tex] rotation symmetry are:

B: rectangle

C: square  

E: regular hexagon

For a shape to have a [tex]180^o[/tex] rotation symmetry, the following must be true.

Options (a) and (d) do not meet any of the above conditions.

However, the stated conditions are true for options (b), (c) and (e); because they have parallel & equal opposite sides; and they have an even number of sides.

Hence, the rectangle, the square and the regular hexagon have a [tex]180^o[/tex] rotation symmetry

See attachment for an illustration of rotation symmetry.

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

The slope of any horizontal line will be zero.

Answer:

slope = m = rise/run = 0/8 = 0

Step-by-step explanation:

Well rise/run is how much it rises over how much it runs.

Note it rises by 0 so 0 on top,

Therefore;

no matter it be 0/1 or 0/1241213261238126836128361  the rise/run also known as slope is always gonna be 0

Reasoning:

0 divided by anything is always 0

Hope this helps

Answer:

slope(m)=change in y/change in x

-7=y-(-2)/x-(-7)

-7=y+2/x+7

-7(x+7)=y+2

-7x-49=y+2

-7x-49-2=y

-7x-51=y (B)

Answer:  y = 1.2x + 1.4

Step-by-step explanation:

1. Write down the coordinates of the first point. Let's assume it is a point with x₁ = -2and y₁ = -1.

2. Write down the coordinates of the second point as well. Let's take a point with x₂ = 3 and y₂ = 5.

3. Use the slope intercept formula to find the slope:

m = (y₂ - y₁)/(x₂ - x₁) = (5-1)/(3-2) = 4/1 = 1.2

4. Calculate the y-intercept. You can also use x₂ and y₂ instead of x₁ and y₁ here.

b = y₁ - m * x₁ = -1 - 1.2*-2 = 1.4

5. Put all these values together to construct the slope intercept form of a linear equation:

y = 1.2x + 1.4

Answer:

x = -3

y = 4

Step-by-step explanation:

Answer:

c(n) = 4n +20

let m = c(n)

m= 4n +20

make n the subject

m -20 =n

4.

inverse function of c(n)= n-20

4

It is a must that one replaces the m with the n in order to get the final answer

Answer:

(-3,4)

Step-by-step explanation:

x + 2y = 5

-3 + (2*4) = 5

-3 + 8 = 5

5 = 5

2x + 3y = 6

(2*-3) + (3*4)=6

-6 + 12 = 6

6 = 6

Answer:

(-3,4)......... multiply the first equation by the coefficient of y i.e 3 (of 2nd equation)...

again multipy the 2nd eq by the coefficient of y i.e 2 (of 1st eq)

and finally solve the eq 3 and 4 ...(solve the both eq formed by multiplying)

Answer:

the answer is b

Step-by-step explanation:

they should have the same slope so just looking at that you cancel out d. But since it says has a y-intercept of 1 then it would cancel out the other 2. d is perpendicular to it not parallel

Answer:

b. [tex]y=5x+1[/tex]

Step-by-step explanation:

Slope-intercept form:

[tex]y=mx+b[/tex]

When two lines are parallel, their slopes are the same. Note the slope of the given equation:

[tex]y=5x+7\\\\m=5[/tex]

The slope is 5, so the slope for the parallel equation will also be 5:

[tex]y=5x+b[/tex]

Now insert the given y-intercept:

[tex]b=1\\\\y=5x+1[/tex]

:Done

Step-by-step explanation:

. We assume, that the number 10 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 10 is 100%, so we can write it down as 10=100%.

4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.

5. Now we have two simple equations:

1) 10=100%

2) x=0.034%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

10/x=100%/0.034%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.034% of 10

10/x=100/0.034

(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x

10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x

10/2941.1764705882=x

0.0034=x

x=0.0034

now we have:

0.034% of 10=0.0034
