plz help to solve it​

Answer:

Step-by-step explanation:

(x₁ , y₁) = (6, -4)  &    (x₂ , y₂) =(-1 , -4)

In these two points, there is no change in y-coordinates. So, the line is parallel to x-axis.

Slope of line parallel to x-axis = 0

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x

x = -(1)+4 = 3

I hope this help you

Answer:

15. x = 112 degrees

18. x = 120 degrees

Step-by-step explanation:

15.

A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.

2a + 44 = 180

2a = 136

a = 68

Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.

x + 68 = 180

x = 112

18.

We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.

3a = 180

a = 60

Now we do the same thing as last time to find x.

x + 60 = 180

x = 120

Answer:

you must send 25 msgs to have the same cost

Step-by-step explanation:

x = n of messages

15+ (0.25x ) = 20 + (0.05x)

0.2x = 5

x = 25

Answer:

at 25 text the plan costs are equal

Step-by-step explanation:

Plan A = $15 + .25t

Plan B = $20 + .05t

when the plan costs are equal $A = $B

then

15 + .25t = 20 + .05t

.25t - .05t = 20 - 15

.2t = 5

t = 25

Answer:

m∠8 = 49°

Step-by-step explanation:

∠7 and ∠8 are same-side interior angles.

Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.

Let's use the variable 'x' to represent the unknown measure of angle ∠8.

[tex]131 +x=180[/tex]

[tex]131-131=0[/tex] (cancels itself out)

[tex]180-131=49[/tex]

[tex]x=49[/tex]

Therefore, the measure of ∠8 is 49°.

Answer:

h=39/4

Step-by-step explanation:

area of a triangle = 1/2(b*h)

base = 8 inches

area =39 square inches

input the values given:

39=1/2(8*h)

multiply the right side by 1/2

39=(1/2)8h

find half of 8

39=1/2*8 (h)

hence,

39=4h

divide both sides by 4

hence,

39/4=h

Answer:

Real and irrational numbers

In geometry, transformations are used to move points from one position to another.

The preimage is given as:

[tex]S =(-3,4)[/tex]

[tex]T = (3,4)[/tex]

[tex]U = (-1,0)[/tex]

The image is given as:

[tex]S' = (-2,2)[/tex]

[tex]T' =(4,2)[/tex]

[tex]U' = (0,-2)[/tex]

Using points S and S' as our reference point, we have:

[tex]S =(-3,4)[/tex] and [tex]S' = (-2,2)[/tex]

Calculate transformation

[tex](x,y) \to S -S'[/tex]

[tex](x,y) \to (-2,2)-(-3,4)[/tex]

Rewrite as:

[tex](x,y) \to (-2--3,2-4)[/tex]

[tex](x,y) \to (-2+3,2-4)[/tex]

[tex](x,y) \to (1,-2)[/tex]

So, the transformation from the preimage to image is:

[tex](x,y) \to (x + 1, y-2)[/tex]

Calculate the lengths of the sides of the preimage and the image

Using the following distance formula, we have:

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

So, we have:

[tex]ST = \sqrt{(-3 - 3)^2 + (4 - 4)^2} = 6[/tex]

[tex]SU = \sqrt{(-3 - -1)^2 + (4 - 0)^2} = \sqrt{20[/tex]

[tex]TU = \sqrt{(3 - -1)^2 + (4 - 0)^2} = \sqrt{32[/tex]

and

[tex]S'T' = \sqrt{(-2 - 4)^2 + (2 - 2)^2} = 6[/tex]

[tex]S'U' = \sqrt{(-2 - 0)^2 + (2 -- 2)^2} = \sqrt{20[/tex]

[tex]T'U' = \sqrt{(4 -0)^2 + (2 -- 2)^2} = \sqrt{32[/tex]

Since

[tex]ST = S'T'= 6[/tex]

[tex]SU = S'U'= \sqrt{20[/tex]

and

[tex]TU = T'U'= \sqrt{32[/tex]

Then, the transformation preserves length

From the graph of [tex]\triangle STU[/tex] and [tex]\triangle S'T'U'[/tex]

Since

[tex]\angle S = \angle S' = 76^o[/tex]

[tex]\angle T = \angle T' = 45^o[/tex]

[tex]\angle U = \angle U' = 59^o[/tex]

Then, the transformation preserves angle measure.
