What is the equation of the following Graph?

Answers

Answer:

From the shape of the graph we can state it is the transformation of the square root function:

f(x) = [tex]\sqrt{x}[/tex]

This is a reflection of f(x) over x-axis, translation 3 units left and 2 units up.

The transformation is:

g(x) = - f(x + 3) + 2

The equation is:

g(x) = - [tex]\sqrt{x+3} +2[/tex]

Its translated square root function

y=√x

Rotate along x axis

y=-√x

shift 3 units left

y=-√x+3

shift 2 units up

y=-√(x+3)+2

Answers

Answer:

y = -1/2x + 5

Step-by-step explanation:

x + 2y = 10

Step 1: subtract x from both sides.

you will get: 2y = -x + 10

Step 2: get the y by itself, you can do this by dividing 2 by both sides.

= 2y = -x + 10

y = -1/2x +10/2

Then, 10/2 simplifies to 5.

So, your answer is: y = -1/2x + 5

The perimeter of a rectangular rose garden is 40 feet. The length of the garden is 5 more
than twice the width. Find the dimensions of the rose garden. (P=2L+2W)

Answers

Answer:

Step-by-step explanation:

Length and width of rectangular rose garden is 15 and 5 feet

Given that;

Perimeter of rectangular rose garden = 40 feet

Length of the garden = 5 more than twice the width

Find:

Dimensions of the rose garden

Computation:

Assume;

Width of garden = a

So,

Length of the garden = 2a + 5

Perimeter of rectangle = 2[l + b]

40 = 2[2a + 5 + a]

40 = 2[3a + 5]

40 = 6a + 10

6a = 40 - 10

6a = 30

a = 5

Width of garden = 5 feet

Length of the garden = 2a + 5

Length of the garden = 2(5) + 5

Length of the garden = 15 feet

Question 2. In the given figure find the value of x in each angle of a triangle.

Very very important Plz.

Answers

Step-by-step explanation:

[tex]\sf\pink{Given}[/tex]

Angle A is ( x + 10 )

Angle B is ( 3x + 5 )

Angle C is ( 2x + 15 )

[tex]\sf\pink{To\: Find}[/tex]

Value of "x" is ?

Explanation :

Rule :

Sum of all angles of a triangle is 180°

Therefore ,

[tex]\longrightarrow\bf{x + 10 + 3x + 5 + 2x + 15 = 180 }[/tex]

[tex]\longrightarrow\bf{x + 3x + 2x + 15 + 5 + 10 = 180 }[/tex]

[tex]\longrightarrow\bf{4x + 2x + 20 + 10 = 180 }[/tex]

[tex]\longrightarrow\bf{6x + 30 = 180 }[/tex]

[tex]\longrightarrow\bf{6x = 180 - 30 }[/tex]

[tex]\longrightarrow\bf{6x = 150 }[/tex]

[tex]\longrightarrow\bf{x = \dfrac{150}{6}}[/tex]

[tex]\longrightarrow\bf\pink{x = 25}[/tex]

Therefore value of x is 25 .

Now, finding the the measure of each angle by putting the value of "x" in their places.

∠A = (x + 10)° => (25 + 10)° => 35°

∠B = (3x + 5)° => (3×25 + 10)° => (75 + 5)° => 80°

∠C = (2x + 15)° => (2 × 25 + 10)° => (50 + 15)° => 65°

Answer:

(x, y, z) = (x, x+2, 3x+1)

Step-by-step explanation:

We can add twice the second equation to the first to get ...

[eq4] -3x +0y +z = 1

Adding the first and second equations gives ...

[eq5] -x +y +0z = 2

Solving [eq4] for z gives ...

z = 3x +1

Solving [eq5] for y gives ...

y = x +2

Then the solution triple is (x, y, z) = (x, x+2, 3x+1).

Millie and Molly’s ages add up to 19 years Millie is three years older than Molly how old are they

Answers

Answer:

Millie is 11. Molly is 8.

Step-by-step explanation:

Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.

19-3=16

Step 2: Divide 2 from 16. You do this because there are two sisters.

16÷2=8

8 will then become Molly's age

Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.

3+8=11

In conclusion, Millie is 11 and Molly is 8.

juan compro: 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6, 4/8 de queso que cuesta $45. cuanto dinero gasto en total? cuanto cuesta un kilo de queso? cuanto cuesta medio kilo de jamón? ¿Cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón? si Juan tiene $430 que puede comprar sin que le sobre ni un peso?

Answers

En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.

Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:

Cuánto dinero gastó en total = valores x fracción comprada3 x 1/4 + 120 x 1 1/2 + 6 x 1/3 + 45 x 4/8 = X0.75 + 180 + 2 + 22.5 = X205.25 = X

Si 4/8 de queso cuestan $45, y 4/8 es igual a 1/2, 1 kilo de queso cuesta $90 (45 x 2).Si 1 kilo de jamón cuestan $120, 1/2 kilo de jamón cuesta $60 (120 / 2).Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129 (3 + 6 + 120).Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas (120 x 3 + 45 + 3 x 5 + 6 + 6 x 0.666).
