Answer:

x = 75

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral are supplementary

x+ 105 = 180

Subtract 105 from each side

x+105-105 = 180-105

x = 75

Answer:

y=-3 , x=5

Step-by-step explanation:

-(x+3y=-4)   new -x-3y=4

                           x-5y=20

                             -8y=24

                             -8     -8

                              y=-3      x-5y=20

                                            x-5(-3)=20

                                             x+15=20

                                                -15= -15

                                                  x=5

The value of x is 5 for the system of equations [tex]x-5y=20[/tex] and[tex]x+3y=-4[/tex].

The given system of equations are :

[tex]x-5y=20[/tex] ...(1)

[tex]x+3y=-4[/tex]...(2)

To solve the equation, multiply equation (2) with -1.

[tex]-x-3y=4[/tex]...(3)

Add equation (1) and (3):

[tex]x-5y-x-3y=20+4[/tex]

Combine like terms:

[tex]-8y=24[/tex]

Divide both sides by -8:

[tex]y=-3[/tex]

Now, we substitute the value of [tex]y = -3[/tex] into either of the original equations to solve for x.

[tex]x - 5(-3) = 20[/tex]

[tex]x + 15 = 20[/tex]

[tex]x = 20 - 15[/tex]

[tex]x = 5[/tex]

Therefore, the solution to the system of equations is[tex]x = 5[/tex] and [tex]y = -3.[/tex]

Answer:

Equation for the function is:

f(x) = (3/2) · 2ˣ

Step-by-step explanation:

We have been provided with 2 points

Point 1 : (3, 12)

Point 2 : (4, 24)

Testing all three equations:

Substitute x of Point 1 in the equation

f(x) = (6/3) · 2³

f(x) = 16

y = 16 ≠ 12

NOT TRUE

Substitute x of Point 2 in the equation:

f(x) = (6/3) · 2⁴

f(x) = 32 ≠ 24

NOT TRUE

Substitute x of Point 1 in the equation

If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...

  P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet

The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...

Step-by-step explanation:

You find volume of the overall figure- 11 x 3 x 13= 429

Then find volumes of missing parts of overall complete figure and subtract from the overall volume....

5 x 4 x 3= 60

429-60=369

Answer:

f(q) = 11/3q+2/3

Step-by-step explanation:

11q - 4 = 3r - 6

Solve for r

Add 6 to each side

11q - 4+6 = 3r - 6+6

11q +2 = 3r

Divide each side by 3

11q/3 + 2/3 = 3r/3

11/3q + 2/3 = r

f(q) = 11/3q+2/3

Step-by-step explanation:

(log 0.04 − 2 log 0.3) / (1 − log 15)

Change 1 to log 10.

(log 0.04 − 2 log 0.3) / (log 10 − log 15)

Use log property: a log b = log bᵃ.

(log 0.04 − log 0.09) / (log 10 − log 15)

Use log property: log a − log b = log (a/b).

log (0.04/0.09) / log (10/15)

Reduce fractions.

log (4/9) / log (2/3)

Change 4/9 to (2/3)².

log ((2/3)²) / log (2/3)

Use log property: log bᵃ = a log b.

2 log (2/3) / log (2/3)

Answer:

x = 3

Step-by-step explanation:

The area of a rectangle is length*width, while for a rectangle it is the length*width over two. Now lets substitute the values given.

3(x+12) = 3x+36 = Area of rectangle

5(2x)/2 = 10x/2 = 5x = Area of triangle

We know that the area of the rectangle is 3 times the area of the triangle, so 3x + 36 = 3(5x) --> 3x+36 = 15x

This gives basic linear equation of 3x + 36 = 15x to solve. Isolate x and solve:

36 = 12x

x = 3

The coordinates for point M is (12, 6)

Section formula is used to find the coordinates of a point that splits a line segment internally or externally into a ratio of m:n.

(x, y) = ( mx2 + nx1/ m+n, my2 + ny1/ m+n)

Given:

Coordinates of A(0, 15) and B (20, 0)

ratio is 3:2

Now,

x1=0, x2= 20, y1= 15, y2=0

let the coordinates of M is (c, d)

Using section formula

c=2*0+3*20/5

c=12

and d= 15*2+ 2*0/5

d= 6

Hence, the coordinates of M are (12, 6).

Answer:

g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left

h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction

Step-by-step explanation:

y = f(x + C)  C > 0 moves it left

So we moved it 8 units to the left

y = −f(x)  Reflects it about x-axis

g(x) = - sqrt(x+8) reflected about the x axis and shifted 8 units to the left

y = f(x) + C  C > 0 moves it up

so we moved it up 1 units

y = Cf(x)  C > 1 stretches it in the y-direction

and stretched it by 2 in the y direction

h(x) = 2 sqrt(x) +1 is stretched by 2 in the y direction and shifted up 1 in the y direction

Answer:

g(x) = - square root (x+8) reflected about the x axis and shifted 8 units to the left

h(x) = 2 square root x) +1 is enlarged by 2 in the y direction and shifted up 1 in the y direction

Answer:

The measure of EF is 4 units

Step-by-step explanation:

If triangle ABC = triangle EDF where the coordinates of A(-1, 1), B(2,4), and C(3,1), what is the  measure of EF?​

To find the measure of EF, we will follow the steps below;

since  triangle ABC = triangle EDF  the coordinates of  triangle ABC  are A(-1, 1), B(2,4), and C(3,1),  then the coordinates of triangle EDF are E(-1, 1), D(2,4), and F(3,1)

To find the measure of EF, we will use the distance formula;

|EF| = √(x₂-x₁)² + (y₂-y₁)²

E(-1, 1)   F(3,1)

x₁=-1

y₁=1

x₂ =3

y₂ = 1

We can now proceed to substitute the values into the formula;

|EF| = √(3+ 1)² + (1-1)²

      = √(4)² + (0)²

      = √(4)²

       =√16

        =4

The measure of EF is 4 units
