Will give brainliest if correct its pretty easy.

Given:

The vertices of the triangle JKL are J(-3, 2), K(2,6), L(8, -1).

To find:

The measures of the sides of triangle JKL and classify it by its sides.

Solution:

Distance formula:

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

Using distance formula, we get

[tex]JK=\sqrt{(2-(-3))^2+(6-2)^2}[/tex]

[tex]JK=\sqrt{(2+3)^2+(4)^2}[/tex]

[tex]JK=\sqrt{(5)^2+(4)^2}[/tex]

[tex]JK=\sqrt{25+16}[/tex]

[tex]JK=\sqrt{41}[/tex]

Similarly,

[tex]KL=\sqrt{\left(8-2\right)^2+\left(-1-6\right)^2}=\sqrt{85}[/tex]

[tex]JL=\sqrt{\left(8-\left(-3\right)\right)^2+\left(-1-2\right)^2}=\sqrt{130}[/tex]

Now,

[tex]JK^2+KL^2=(\sqrt{41})^2+(\sqrt{85})^2[/tex]

[tex]JK^2+KL^2=41+85[/tex]

[tex]JK^2+KL^2=126[/tex]

[tex]JK^2+KL^2\neq JL^2[/tex]

Since, measure of all sides are different and sum of squares of two smaller sides is not equal to the square of largest side, therefore the triangle is scalene triangle.

Answer:

your answer will be (B)

Answer:

y = -2/3x -5

Step-by-step explanation:

First, let's fill in our equation of y = mx + b

(6, -9) is the coordinate we will be subsituting

If the equation that s to the one we are solving we must turn its slope into it's negative reciprocal, which would go from 3/2 to -2/3

Now let's substitute and solve

y = mx + b

(-9) = -2/3(6) + b

-9 = -4 +b

+4   +4

-5 = b

Now we create the equation

y = -2/3x -5

Answer: -3 :)

Step-by-step explanation:

Answer: It's false.

I believe you would do (5-3) first.

Answer:

false

Step-by-step explanation:

Answer: -12 + (4/5) + 31 = 18.2

y=2x-3

y=2x+3

Since the both expressions 2x-3 and 2x+3 are equal to y, set them equal to each other forming an equation in x.

2x-3=2x+3

Cancel equal terms on both sides of the equation

-3=3

The statement is false for any value of x and y , so there is no solution

Answer:

1. 9 cm

2. 50%

3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).

Step-by-step explanation:

1. The long side is clearly the 6 cm side. multiply it by 1.5x (150%) and you get 9.

2. 2 is 50% of 4 and 3 is 50% of 6.

3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).

Answer:

  (x, y) = (-2, 1)

Step-by-step explanation:

Equate the two expressions for y.

  -5x -9 = 2x +5

  -14 = 7x . . . . . . . .add 5x-5

  -2 = x . . . . . . . . . divide by 7

Then ...

  y = 2(-2) +5 = 1

The solution is (x, y) = (-2, 1).

Answer:

20789

Step-by-step explanation:

The equation of exponential growth is y=A(1+r)^t

A=10,000

r (rate)=0.05 (5% as a decimal)

t (time)=15 (2035-2020=15)

y=10,000(1+0.05)^15

y=20789.2817

you can't have part of a person, so y=20789

Answer:

She will take 10 weeks to save the money for the DVD player

Step-by-step explanation:

Let w = Lianne's weekly allowance.

The DVD player costs 2 1/2 times her weekly allowance, thus

DVD cost = 5/2w

She gets w every week but spends 3/4w on other things, thus the remaining money is

Weekly savings =w - 3/4w = 1/4w

To know the number of weeks needed, we divide the DVD cost by the weekly savings:

[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]

Operating:

[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]

N = 10

She will take 10 weeks to save the money for the DVD player

Answer:

  D) $400

Step-by-step explanation:

We are given the relations ...

  s = 0.75m

  s = 300

Then we can find m by equating the expressions for s:

  0.75m = 300

  m = 300/0.75 = 400

Meifen's savings is $400.

Answer:

x=0

Step-by-step explanation:

You can substitute 2-6y in for x to create

9y +2(2-6y) = 3

9y + 4 -12y = 3

-3y = -1

y=1/3

Then plug in y for x=2 -6y

x= 2-6(1/3)

2-2=x

x=0
