Answer:

1,2 = 1,negative2

3,6 = 3,negative 6

-1,2 = negative 1, negative 2

-2,-2 = negative2, 2

Step-by-step explanation:

Sorry all i could do was reflect the coordinates across the x-axis.

The figure reflected along x-axis will have vertices A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

When we reflect a figure along the x-axis the coordinate point of y changes its sign, (x, y) becomes (x, - y).

Think of holding the x-axis with two fingers and rotating it.

Given, we reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)

across the x-axis.

∴ The rotated coordinate will be A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

Answer:

m=−bd+t

Step-by-step explanation:

t=bd+m

flip equation

bd+m=t

Step 2: Add -bd to both sides.

bd+m+−bd=t+−bd

m=−bd+t

On solving for M, we get -  

M = t - bd

We have the following expression -

t = bd + M.

We have to solve for ' M '.

On solving, we get -

nx + a = [tex]$\pi[/tex]

x =  [tex]$\frac{\pi -a}{n}[/tex]

According to the question, we have -

t = bd + M

t - bd = M

M = t - bd

Hence, on solving for M, we get -  

M = t - bd

Answer:

Let x= liters of 18% solution to be added to a 10% solution.

20-x= liters of 10% solution to be mixed with 18% solution.

..

18%(x)+10%(20-x)=15%(20)

.18x+2-.1x=3

..08x=1

x=1/.08=12.5

ans:

12.5 liters of an 18% alcohol solution must be added to a 10% alcohol solution to get 20 L of a 15% acohol solution.

Answer:

Angle B and Angle D are both 101 degrees

Step-by-step explanation:

Consecutive Angles in a parallelogram are supplementary (add up to 180 degrees).

Given that fact, we can deduce the measure of angle B.

180-79=101.

Angle D has the same setup since Angle D and C are consecutive along with Angle C and B.

180-79=101.

Therefore, both Angle B and D are 101 degrees.

Technically they would both be a function because each x value has a different y value but i'll say the straight one would be the better function. Warning Both graphs are proper functions. It's just that the first one would be a better answer if there was only one answer choice.

Answer:

a) The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

b) The rate of increase after one day is of 0.0915.

Step-by-step explanation:

The brightness after t days is given by:

[tex]B(t) = 4.2 + 0.45\sin{(\frac{2\pi t}{4.4})} = 4.2 + 0.45\sin{(0.4545\pi t)}[/tex]

A) Find the rate of change of the brightness after t days.

This is [tex]B^{\prime}(t)[/tex]

The derivative of a constant is 0, the derivative of [tex]\sin{at}[/tex] is [tex]a\cos{at}[/tex]

So, in this case, we have that:

[tex]B^{\prime}(t) = 0.45*0.4545\pi\cos{(0.4545\pi t)} = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]

B) Find the rate of increase after one day.

This is [tex]B^{\prime}(1)[/tex]. So

[tex]B^{\prime}(1) = 0.204525\pi\cos{(0.4545\pi)} = 0.0915[/tex]

The rate of increase after one day is of 0.0915.

Answer:

range is 2

Step-by-step explanation:

The range of values for the actual value is 2.

A range is the simplest measurement of the difference between the values ​​in a dataset. To find the range, subtract the minimum value from the maximum value and ignore the other values. Where the minimum is 155 and the maximum is 720.

The statistical range for a particular dataset is the difference between the maximum and minimum values. For example, if the specified record is {2,5,8,10,3}, the range is 10 – 2 = 8. Therefore, the range can also be defined as the difference between the highest and lowest observations.

Answer:

Work= force(F) * distance (s)

weight is a force and so

F=weight=mass *acceleration due to gravity

=1000*10=10000N

S=?

To find s,

F= ma

a=F/m=10000/10

a=10m/s²

Using Newton's third equation of motion

v²= u²+2as

30²= 20²+2*10*s

900–400=20s

500=20s

s=500/20= 25m

Work =F*s

Work=10000*25

Answer:

A. y = 2

B. x = 7/2

C. y = 12/5

D. x = 6

Step-by-step explanation:

A. Determination of y .

2x + 5y = 12

x = 1

2(1) + 5y = 12

2 + 5y = 12

Collect like terms

5y = 12 – 2

5y = 10

Divide both side by 5

y = 10 / 5

y = 2

B. Determination of x

2x + 5y = 12

y = 1

2x + 5(1) = 12

2x + 5 = 12

Collect like terms

2x = 12 – 5

2x = 7

Divide both side by 2

x = 7/2

C. Determination of y

2x + 5y = 12

x = 0

2(0) + 5y = 12

0 + 5y = 12

5y = 12

Divide both side by 5

y = 12/5

D. Determination of x

2x + 5y = 12

y = 0

2x + 5(0) = 12

2x + 0 = 12

2x = 12

Divide both side by 2

x = 12/2

x = 6

Answer:

9

Step-by-step explanation:

The triangle provided is an equilateral one, which means that the length of all sides is equal.

Let's start by taking two and finding x.

8x+1 = 3x+6 (Subtract 3x from both sides)

5x+1 = 6 (Subtract 1 from both sides)

5x = 5 (Divide 5 from both sides)

x = 1

Now we substitute x in all the equations to find the length.

8(1) + 1 = 9

3(1) + 6 = 9

4(1) + 5 = 9

Length = 9

Answer:

  1.7 degrees is warmer than -3.4 degrees

Step-by-step explanation:

You can find these two numbers on a number line. Warmer (and greater) is to the right.

Step-by-step explanation:

step 1. 12x - 15 - 12x = 7x + 20

step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)

step 3. -15 = 7x + 20 (adding like terms)

step 4. -35 = 7x (subtract 20 from both sides)

step 5. this step is incorrect.

step 6. -5 = x ( divide both sides by 7)

step 7. x = -5 (put the variable first).
