Question 9 of 10
Which inequality is shown in this graph?

Answer:

[tex] \frac{ - 5 + \sqrt{( {5})^{2} } - 4(4)( - 6) }{ 2(4)} [/tex]

Answer: 315/15 gallons

Step-by-step explanation:

You have to divide 315 by 15

Answer:

Step-by-step explanation:

V = x(14 - 2x)(18 - 2x)

V = (14x - 2x²)(18 - 2x)

V = (252x - 28x² - 36x² + 4x³)

V = 4x³ - 64x² + 252x

V' = 12x² - 128x + 252

0 = 3x² - 32x + 63

x = (32 ±√(32² - 4(3)(63))) / (2(3)

x = (32 ± √268) / 6

x = 8.06 inches, which we ignore as this would mean we have no material left at all in the 14 inch dimension.

or

x = 2.60488... 2.60 inches

Vmax = 0.60(14 - 2(2.60))(18 - 2(2.60)) = 292.86478... = 292.86 inches³

Answer:

45

Step-by-step explanation:

We can divide

65 divided by 13.

65 divided by 13 is 5.

Now we mutliply that 5 to the 9.

9 times 5 is 45.

Answer:

The ratio equivalent to 5/3 is

For example, if we have a ratio 250 to 150, we can simplify it by dividing both numbers by 10 and then by 5 to get 5 to 3: 250 : 150 25 : 15 5:3 . The ratio 5 to 3 is the simplest form of the ratio 250 to 150, and all three ratios are equivalent.

Answer:

  girls : boys = 13 : 7

  7 boys in the math class

Step-by-step explanation:

We assume that the number of boys is the total number of students less the number of girls. In ratio units, that is ...

  girls : boys = girls : (total - girls) = 13 : (20 -13)

  girls : boys = 13 : 7

There are 7 boys in the math class.

_____

Additional comment

We are only told the ratio, not any actual numbers. In order to answer the question, we must assume a total for the number of students in the class. It is convenient to assume that total is 20. There is nothing in the problem statement to indicate it is not some multiple of 20. The number of boys will be 7/20 of the total number of students in the math class.

Answer :-

According to the question ,

We know Point slope form of the line as ,

Substitute ,

Hence the equation of the line is 3x -2y-4=0 .

Answer:

Step-by-step explanation:

Use the form y = mx + b and plug in your known point

y = 3x/2 + b

1 = 3(2)/2 + b

1 = 3 + b

b = -2

y = 3x/2 - 2

we can use a plotting calculator to verify our result.

Answer:

vertex: (6, -9)

y intercept: (0, 27)

X = 3, 9

Step-by-step explanation:

Finding Vertex (Part A)

Consider the formula -b/2a. This formula gives you the x-coordinate of the vertex.

y = 1x^2 - 12x + 27

a = 1

b= -12

c =27

-b/2a = - (-12)/2(1) = 12/2 = 6 (x-coordinate of vertex)

When solving for the y-coordinate of the vertex you will need to substitute your 'x" back into the equation.

y = 1(6)^2 - 12(6) + 27

y = 36 - 72 + 27 = -9 (y-coordinate of vertex)

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

Y- Intercept (Part B)

When looking for the y-intercept your "x" must always be 0.

Substitute 0 in every "x" in equation.

y = 1(0)^2 - 12(0) + 27

y = 27

y intercept: (0, 27)

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

X- Intercepts (Part C)

To find the values of "x" factor.

y = 1x^2 - 12x + 27

0 = 1x^2 - 12x + 27

0 = (x  - 3     )(x   -  9 )

(x-3) = 0             (x-9) = 0

x = 3                    x = 9

Answer:

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Both the first and second signs are negative,

Let α and β are the roots of the ,

then, we know that the relationship between the zeroes and coefficients of quadratic equations:

Since the product of roots is positive.

So, the signs of the factors will be one positive and one negative.

Hence, Option 'D' is correct.

Answer:

yes it 6 hours

Step-by-step explanation:

Answer:

8 hours

Step-by-step explanation:

if the jacket is 32$, then we have to go beyond the graph, and make a function line.

so we can find the slope, how much money does she get per hour?

she gets 4$ per hour, meaning the equation is y=4x

y is the amount of money, x is the amount of hours.

substitute our desired amount of money, 32

32=4x

divide each side by 4 and you get 8

Answer:

y = 6x + 17

Step-by-step explanation:

First you can find the slope:

m = (y2-y1) / (x2-x1)

m = (-7 - (-1)) / (-4 - (-3))

m = (-7 + 1) / (-4 + 3)

m = -6 / -1

m = 6

_______

Then we can plug what we know into the point-slope form:

y - y1 = m (x - x1)

(you can pick either one of the points to plug in as (x1, y1))

y - (-7) = 6 (x - (-4))

y + 7 = 6 (x + 4)

_______

Now we can change the point-slope form into slope-intercept form by solving for y:

y + 7 = 6 (x + 4)

y + 7 = 6x + 24

y = 6x + 17

Answer:

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Step-by-step explanation:

See it's not a function

The statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Function is a type of relation, or rule, that maps one input to specific single output.

WE have been given a domain figure.

We can see that the input values has more than one output values.

therefore, it cannot be a function Because in a function every input value has a unique y value.

Here there is 4 values for one x input.

x = 3

y = 2, 4, 5, 6

So it's a relation

Hence, the statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.
