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:

[tex]y=\frac{1}{3} x[/tex]

Step-by-step explanation:

we need a function that when we plug the value of x, we get the given value of y.

In the coordinate point

(-9, -3)

the x and y values are:

x = -9

y = -3

so we can see that the value of y is one third of the x value (because -9/3 = -3):

[tex]y=\frac{1}{3} x[/tex]

this is also true for the secod point:

(-12, -4)

here the x and y values are:

x = -12

y = -4

again the y value is one third of the x value (because -12/3 = -4):  

[tex]y=\frac{1}{3} x[/tex] ⇒ this is the equation that represents the function.

Answer:

The area of the base is 16 ft^2

The length of the prism is  4 feet.

The width of the prism is 4 feet.

Step-by-step explanation:

The formula for volume of a prism is given by

V=Bh where B is the area of the base and h is the height

96 = B h

We know h is 6

96 = B6

Divide each side by 6

16 = B

The area of the base is 16 ft^2

Since the base is a square

B =16ft^2

since it is a square, the area is given by

B =s^2 where s is the side length

16 =s ^2

Taking the square root

4 = s

The length of the prism is  4 feet.

The width of the prism is 4 feet.

Answer:

1.  square base        =  A = 16 ft² (Base area of square prism)

2. Length of prism  = 4 ft

3. Width of prism    =  4 ft

Step-by-step explanation:

given:

Volume of a square base prism (V) = 96 ft³

height (h) = 6 ft

Length (L) = L

Width (W) = W

find:

1.  square base

2. Length of prism

3. Width of prism

---------------------------------

1.

Vol of prism = base area (A) x height (h)

V = A * h

96 = A * 6

A = 96 / 6

A = 16 ft² (Base area of square prism)

2.

Length of prism = A = s²

16 = s²

s = √16

s = 4 ft.

therefore the Length of a square base prism = 4 ft

3.

square base = L = W

therefore the Width of a square base prism = 4 ft

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: 16

Step-by-step explanation:

The constant of proportionality is a ratio that exist between two directly proportional quantities. From the question, recipe says to use 1.5 cups of flour to make 24 cookies.

y = the number of cookies made

x = the number of cups of flour used

y = kx

k = y/x

k = 24/1.5

k = 16

Therefore, the constant of proportionality which relates the number of cookies made, y, to number of cups of flour used, x is 16.

x = 5.7

Step-by-step explanation:

Use the Triangle-Angle-Bisector Theorem.

[tex]\frac{CD}{DB}[/tex] = [tex]\frac{AC}{AB}[/tex]

Substitute the corresponding side lengths.

[tex]\frac{2}{2.8}[/tex] = [tex]\frac{x}{8.1}[/tex]

Cross Multiply.

16.2 = 2.8x

Divide each side by 2.8.

[tex]\frac{16.2}{2.8}[/tex] = [tex]\frac{2.8x}{2.8}[/tex]

Since 2.8 cancels out 2.8x, your left with x.

Then divide 16.2 by 2.8.

x = 5.7

Option d) is correct

Step-by-step explanation:

Given: [tex]y=\left | x \right |[/tex] is translated 1 unit up and 6 units to  the left

To find: equation of the function when the given function is translated 1 unit up and 6 units to  the left

Solution:

See the graph of [tex]y=\left | x \right |[/tex] .

As the graph of the given function is translated 1 unit up and 6 units to  the left, the graph becomes as shown in the image attached.

The equation of the function when the given function is translated 1 unit up becomes [tex]y-1=|x|[/tex] and when this function is translated 6 units to  the left, the equation becomes [tex]y-1=|x+6|[/tex]

[tex]y=|x+6|+1[/tex]

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

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)

Divide.

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
