identify the vertex of the graph

Answers

Answer:

(-1,-3)

Step-by-step explanation:

Answer:

y = a(x – h)2 + k,

Step-by-step explanation:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.

there are 12 girls in Chloe's first grade class. The ration of girls to boys is 6:5. How many boys are in Chloe's class?

Answers

There are 10 boys in Chloe’s class. Since the ratio is 6:5 and there are 12 girls and 12/2 is 2 then you multiply 5 by 2 to get 10.

Last year at a certain high school, there were 110 boys on
the honor roll and 75 girls on the honor roll. This year, the
number of boys on the honor roll decreased by 20% and the
number of girls on the honor roll decreased by 4%. By what
percentage did the total number of students on the honor
roll decrease? Round your answer to the nearest tenth (if
necessary).

Answers

.86486486 percent but round it

Answer:

13.5 if you round it

Step-by-step explanation:

Find the new amount of people who got the honor role and subtract that from the total. 185-160=25....which is 13.5% of 1185

A bill of $424 was paid with $5 bills and $2 bills. A total of 128 bills were used. How
many of them were fives?

Answers

Answer: 56

Step-by-step explanation:

Let the number of $5 be x

Let the number of $2 be y.

Based on the information given, we can form an equation as:

x + y = 128 ........ i

5x + 2y = 424 ....... ii

Multiply equation i by 2

Multiply equation ii by 1

2x + 2y = 256 ...... iii

5x + 2y = 424 ....... iv

Subtract iii from iv

3x = 168

x = 168/3

x = 56.

Therefore, there were 56 $5 bills.

What is an equation of the line that passes through the points (0, 3) and (5, -3)?

Answers

Answer:

y = -6/5x + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 3/ 5 - 0

= -6/5

To find the y-intercept, you need to plug the coordinates into the equation,

y = -6/5x + b

3 = -6/5(0) + b

3 = 0 + b

b = 3

The equation is y = -6/5x + 3

Resuelva y responda a la pregunta: Andrés es mayor que su hermano Alex. Dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés y, dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora. ¿Qué edades tienen los hermanos?

Answers

Answer:

Andrés tiene 15 años y Alex tiene 12 años.

Step-by-step explanation:

Como el enunciado dice que dentro de 3 años, la edad de Alex será la edad que tiene ahora Andrés puedes escribir una ecuación que indique que la edad de Andrés es igual a la edad de Alex más 3:

x=y+3, donde:

x es la edad de Andrés

y es la edad de Alex

Además, como se indica que dentro 9 años, la edad de Andrés será el doble de la edad que Alex tiene ahora puedes escribir una ecuación que indique que la edad de Andrés más 9 es igual a dos veces la edad de Alex:

x+9=2y

Ahora puedes reemplazar x=y+3 en x+9=2y y despejar y:

y+3+9=2y

12=2y-y

y=12

Finalmente, puedes reemplazar el valor de y en x=y+3 para encontrar el valor de x:

x=y+3

x=12+3

x=15

De acuerdo a esto, la respuesta es que Andrés tiene 15 años y Alex tiene 12 años.

At a garage sale, Samuel purchased used books and DVDs. He bought a total of 18 items and spent $11. Each book cost $0.50 and each DVD cost $0.75. How many books did Samuel purchase?

Answers

Answer: 10 books

Step-by-step explanation:

Let the number of books bought be represented by x.

Let the number of dvds bought be represented by y.

The information given in the question can be formed into an equation as:

x + y = 18 ........ i

0.50x + 0.75y = 11 ....... ii

Multiply equation i by 0.75

Multiply equation ii by 1

0.75x + 0.75y = 13.50 ........ iii

0.50x + 0.75y = 11 ........ iv

Subtract iv from iii

0.25x = 2.50

x = 2.50/0.25

x = 10

Samuel bought 10 books

Answers

Answer:

0.7 km per minute , -0.17 km per minute

Step-by-step explanation:

The computation of the average speed is shown below

As we know that

Average speed = Total distance ÷ total time

= (4 + 2 + 1) ÷ (32 + 22 + 16)

= 0.7 km per minute

Now the velocity is

= Change in displacement ÷ change in time

= (4 - 2 - 1) ÷ (32 -22 -16)

= 1 ÷ -6

= - 0.17km per minute
