Answer:

P( - 1, 3)

Step-by-step explanation:

J(- 2, 4), P(x, y), K(3, -1)

KP = 4JP and KP + JP = JK

5JP = JK

JP = [tex]\frac{1}{5}[/tex] JK

JK = 5√2

JP = √2

KP = 4√2

2 = (x + 2)² + (y - 4)²

Step-by-step explanation:

Step 1: Define systems

2x + 5y = 16

3x - 5y = -1

Step 2: Solve for x

Step 3: Solve for y

Answer:

(3, 2)

Step-by-step explanation:

2x + 5y = 16 ........ (1)

3x - 5y = - 1 ......... (2)

(1) + (2)

( 2x + 3x ) + [ 5y + ( - 5y)] = 16 + (- 1)

5x = 15 ⇒ x = 3

2(3) + 5y = 16 ⇒ y = 2

Answer:

The equation of required line is: [tex]\mathbf{x+y=5}[/tex]

Step-by-step explanation:

We need to find an equation of the line that passes through the point (2,3) and is parallel to the line x+y=4

For finding an equation of line, we need to find slope and y-intercept of the line.

Finding slope:

If the lines are parallel their slope is same

We are given: x+y=4

Writing in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept

[tex]x+y=4\\y=-x+4[/tex]

Comparing [tex]y=-x+4[/tex] with [tex]y=mx+b[/tex] the slope m is -1

So, slope of given line is -1

It is parallel with required line, so they have same slope.

The slope of required line is m=-1

Finding y-intercept

Using slope m=-1 and point(2,3) we can find y-intercept

Using slope-intercept form: [tex]y=mx+b[/tex]

[tex]y=mx+b\\3=-1(2)+b\\3=-2+b\\b=3+2\\b=5[/tex]

So, y-intercept is: b=5

The equation of required line having slope m=-1 and y-intercept b = 5 is

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

So, equation of required line is: [tex]\mathbf{x+y=5}[/tex]

The equation of the line that passes through the point (2,3) and is parallel to the line x+y=4 is y  =  -x  +  5

Two equations are parallel if they have equal slope

For the equation x + y = 4

Rewrite the equation in the form y = mx + c

y  =  -x  +  4

Compare y = -x + 4 with y = mx + c

The slope, m = -1

The equation parallel to x + y = 4 will also have a slope, m = -1

The line passes through the point (2, 3)

That is, x₁ = 2, y₁ = 3

The point-slope form of the equation of a line is:

y - y₁  =  m(x  -  x₁)

Substitute x₁ = 2, y₁ = 3 into y - y₁  =  m(x  -  x₁)

y - 3 = -1(x  - 2)

y - 3 = -x + 2

y  =  -x  +  2  +  3

y  =  -x  +  5

The equation of the line that passes through the point (2,3) and is parallel to the line x+y=4 is y  =  -x  +  5

Answer:

he needs to work 3 more days in order to make 250 dollars for his vacation

Step-by-step explanation:

Answer:

1). 250 - 60t

2). 60t

Step-by-step explanation:

"Camila started her collection with 250 cards and decreased by 60 cards each year"

Starting number of cards with Camila = 250

Decrease in number of cards each year = 60

Decrease in number of cards after 't' years = 60t

Number of cards after 't' years = 250 - 60t

"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."

Number of cards with Camila = 0

Number of cards grew each year = 60

Number of cards after 't' years = 60t + 0 = 60t

Answer:

Length of AB is [tex]\sqrt{106}[/tex]

Step-by-step explanation:

Let us use the rule of the distance To find the length of AB

∵ A = (9, -3)

∵ B = (0, 2)

∴ x1 = 9 and y1 = -3

∴ x2 = 0 and y2 = 2

∵ AB = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]

→ Substitute the values of x1, x2, y1, and y2 in the rule to find AB

∴ AB = [tex]\sqrt{(0-9)^{2}+(2--3)^{2}}[/tex]

∴ AB = [tex]\sqrt{(-9)^{2}+(2+3)^{2}}[/tex]

∴ AB = [tex]\sqrt{81+(5)^{2}}[/tex]

∴ AB = [tex]\sqrt{81+25}[/tex]

∴ AB = [tex]\sqrt{106}[/tex]

→ The square root of 106 is the simplest radical form

∴ Length of AB is  [tex]\sqrt{106}[/tex]

Answer:(9,-3)

Step-by-step explanation:

You just have to flip the numbers

Step-by-step explanation:

let the equation be y = mx + b.

m = (6 - 2)/(12 - (-4)) = 1/4

sub (12, 6):

6 = 1/4(12) + b

b = 3

therefore, equation of the line is y = 1/4x + 3, aka option 4

Answer:

y = 0.25x + 3

Step-by-step explanation:

solve for slope:

(6-2)/(12+4) = 1/4

solve for b:

6 = 12(1/4) + b

6 = 3 + b

b = 3

equation can also be y = 1/4x + 3

Answer: 22.9890 is the answer

Answer:

23.0 will be your answer.

Step-by-step explanation:

When you round to the nearest tenth, you go one decimal place past the decimal. This is the number that will be rounded up or stays the same.

Then we go to 1 decimal place past that one. This number determines if the number will round up or stay. If the number is 5 and greater, then it will make the number before round-up. If the number is 4 or less, then the number will stay the same.

In this case, the 8 will make the 9 round up, resulting in the 9 become a "10", and that one gets added to the 2, or the next digit to the left.

- Ripper

Step-by-step explanation:

The number of the quarters coins are 14. Then the correct option is C.

The solution of the equation means the value of the unknown or variable.

Kat has 19 coins, all quarters and dimes, that are worth a total of $4.

The system of equations that can be used to find the number of quarters, q, and the number of dimes, d, she has is shown.

           q + d = 19

                 d = 19 – q ...1

0.25q + 0.1d = 4        ...2

Solve the equation, we have

0.25q + 0.1(19 – q) = 4

0.25q – 0.1q + 1.9 = 4

                     0.15q = 2.1

                           q = 14

Then the correct option is C.
