Answer:

The rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

Step-by-step explanation:

Considering the point

[tex]P(x, y)[/tex]

If we reflect a point [tex]P(x, y)[/tex] across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of the point P flips their places and the sign of the coordinates reverses.

Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:

P(x, y) ⇒ P'(-y, -x)

For example, if we reflect a point, let suppose A(1, 3), across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of point A flips their places and the sign of the coordinates reverses.

Hence,

A(1, 3) ⇒ A'(-3, -1)

Answer:

-8, -3, 2 ad 7

Step-by-step explanation:

This graph shown is a polynomial function. The solution is the point where the curves cuts the x axis. From the diagram we can see that the curves cuts the x axis at four points.

The points are at x1 = -8, x2 = -3, x3 = 2 and x4 = 7

Hence the real solutions to the function f(x) = 0 are -8, -3, 2 ad 7

Answer:

Ratio of student who signed up for art club:

1/5

Ratio who signed other club:

4/5

Step-by-step explanation:

First find out ratio who signed up for art club

you have 16 out of 80

find the common factor: 16

16/16 = 1

80/16 = 5

so 1/5

other clubs is the rest so 5/5 - 1/5 = 4/5

please give thanks :)

Answer: 50 miles per hour

Step-by-step explanation:

Find out the length of the normal route.

Distance = Speed * time

= 48 * 40/60

= 32 miles

The detour is 8 miles longer so the length is;

= 32 + 8

= 40 miles

What speed should he travel at to make it in 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

= 40 / (48/60)

= 50 miles per hour

Answer:

50 miles per hour :)

Step-by-step explanation:

Distance = Speed * time = 48 * 40/60 = 32 miles

Detour is 8 miles longer so = 32 + 8 = 40 miles

In 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

50MPH= 50 miles per hour

Step-by-step explanation:

Answer:

113.04

Step-by-step explanation:

To calculate a circle's area, the formula is Pi R Squared. R is radius. Radius squared would be 36. (6*6) Now, multiplied by Pi, the area would be:  113.04. (36*3.14)

Answer:

113.04

Step-by-step explanation:

The radius of a circle is 6 yards. What is the circle's area?

r=6 yd

Use 3.14 for ​.

square yards

You answered:

113.1

square yards

remember

Use this formula to find the area from the radius.

A=​r2

Use 3.14 as an approximation for ​.

​≈3.14

solve

The radius is 6 yards. Replace r by 6 in the formula.

A

= ​r2

≈ 3.1462

≈ 3.1466

≈ 113.04

The area is about 113.04 square yards.

Step-by-step explanation:

2(x+2) + 3x

2x + 4 + 3x = 34

5x + 4 = 34

5x = 34–4

5x = 30

x = 30/5

Answer:

Split the equation into two equations:

4x - 3 ≤ 7

or

-(4x - 3) ≤ 7

The overall solution is the combination of the two individual solutions.

Answer:

D. y = −0.054(44) 44.54

Step-by-step explanation:

The difference in years from 1976 to 1996 is 20 years

But from 1976 to 2020 the years would be 44

So here put the value of x as 44  

Therefore the equation that could be used for predict the winning time for the year 2020 is y = −0.054(44) 44.54

Hence, the correct option is d.

ANd the rest of the options are incorrect

Answer:

He needs to sell 25 pieces of artwork.

Step-by-step explanation:

$500 for an oil painting.

$300 for a charcoal sketch.

56 pieces of artwork total.

$20,000 goal.

500 + 300

= 800

$800 for 1 oil painting and 1 charcoal sketch.

20,000 ÷ 800

= 25

He needs to sell 25 pieces of artwork to make $20,000.

Answer:

51 and  -27

Step-by-step explanation:

The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:

x + y = 24

The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:

x - y = 78

Now solve equation B for x to get the revised equation B:

x - y = 78

x = 78 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 24

78 + y + y = 24

78 + 2y = 24

2y = -54

y = -27

Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:

x + y = 24

x + -27 = 24

X = 51

Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:

Sum: 51 + -27 = 24

Difference: 51 - -27 = 78

Answer:

The numbers are 27 and 51

Explanation

x - y = 24

x + y = 78

Add together the equations

2x = 102

x = 51

Put into equation

51 - y = 24

27 = y

Answer:

one pound is 4 dollars and 12 pounds would cost 48 dollars

Answer:

No because if you set them equivelent to each other you get 12=0

Step-by-step explanation:

1/4(12x + 24) - 9x = -6(x + 1)

3x + 6 - 9x = -6x - 6

-6x + 6 = -6x - 6

12 = 0x

Step-by-step explanation:

Step 1: Define

Point (-12, 1)

Point (4, 1)

Step 2: Find slope m

Answer:

zero; it is a horizontal line

Step-by-step explanation:

equation of slope: [tex]\frac{y1-y2}{x1-x2}[/tex]         (-12, 1) (4, 1)

[tex]\frac{1-1}{-12-4}[/tex] = [tex]\frac{0}{-16}[/tex]

Because the numerator is zero, the slope of the line is zero. It is a horizontal line.

Answer:

The answer is

[tex] \sqrt{65} [/tex]

Step-by-step explanation:

We need to find the distance as instructed.

Its formula is:

[tex]d = \sqrt{(x_2 - x_1) ^{2} + (y_2 - y_1)^{2} } [/tex]

Let's plug in according to the formula and solve.

[tex]d = \sqrt{(x_2 - x_1) ^{2} + (y_2 - y_1)^{2} } \\ d = \sqrt{( - 7 - 1) ^{2} + (2 - 3)^{2} } \\ d = \sqrt{64 + 1} \\ d = \sqrt{65} [/tex]
