what is the average rate of change?​

Answer:

y=-4

Step-by-step explanation:

Answer:

(0,6), and (18,0)

Step-by-step explanation:

2x +6y = 36

6y = -2x +36

y =(-2/6) x+ 36/6

y=(-1/3)x +6

compare this equation to y=mx+b where b is the y-intercept so the

y-intercept is a point at (0, 6)

to find the x-intercept make the equation equal to 0

(-1/3)x+6=0 subtract 6 in both sides

(-1/3)x = -6 cross multiply

-x = 3*-6

x=18 so the

x-intercept is a point at (18,0)

Answer:

The 2 integers would be: 2 and 8

Step-by-step explanation:

2 + 8 = 10

Reciprocal of 2: 1/2

Reciprocal of 8: 1/8

1 / 2 - 1 / 8 = 4/8 - 1/8 = 3/8

Answer:

The unit rate is .6¢

Step-by-step explanation:

To find unit rate, you divide the price by the amount of whatever it is that there are. In this case its cans of beans. So it would by 9.60 divided by 16 which equals .6.

Answer:

vertex = ( - [tex]\frac{3}{2}[/tex],  [tex]\frac{75}{4}[/tex] )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

Given

y = - 3(x - 1)(x + 4) ← expand the factors using FOIL

  = - 3(x² + 3x - 4) ← distribute parenthesis by - 3

  = - 3x² - 9x + 12 ← in standard form

with a = - 3 and b = - 9 , thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]

Substitute this value into the equation for corresponding value of y

y = - 3( - [tex]\frac{3}{2}[/tex] - 1)( - [tex]\frac{3}{2}[/tex] + 4)

  = - 3 × - [tex]\frac{5}{2}[/tex] × [tex]\frac{5}{2}[/tex]

  = - 3 × - [tex]\frac{25}{4}[/tex]

  =  [tex]\frac{75}{4}[/tex]

Thus

vertex = ( - [tex]\frac{3}{2}[/tex], [tex]\frac{75}{4}[/tex] )

Answer:

a = 2.5

Step-by-step explanation:

a - a = -5

-2a = -5

5 = 2a

5 by 2 = 2.5

Therefore a = 2.5.

-3x less than 10.9

x =10.9/-3

Answer:

Answer: 23%

Step-by-step explanation:

From the question, we are informed that a new pair of shoes cost $78 and that they are on sale for $60.06.

The percent of change will be calculated as:

Change/ Cost price × 100

= [(78 - 60.06) / 78] × 100

= (17.94 / 78) × 100

= 0.23 × 100

= 23%

Answer:

Option C

Step-by-step explanation:

Nonlinear functions are functions that have the index of x not being 1.

C is a Nonlinear function because it's index is 4.

Answer:

6.  y = [tex]\frac{11}{6}[/tex]x + 14

7.  y + 2 = [tex]\frac{-11}{12}[/tex](x-8)   or    y - 9 = [tex]\frac{-11}{12}[/tex](x+4)

8.  y = 0x + 236   or y = 236

Step-by-step explanation:

point slope form: y-[tex]y_{1}[/tex] = slope * (x-[tex]x_{1}[/tex])

* [tex]y_{1}[/tex] is the y value of a certain point

* [tex]x_{1}[/tex] is the x value of a certain point

slope intercept form: y=mx+b

*m is the slope

*b is the y-intercept

Answer:

8/15

Step-by-step explanation:

you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1

then you multiply across

2/15 * 4/1

you first multiply 2 and 4 and your answer will be 8 which is the numerator

then multiply 15 and 1 which is 15, the denominator

then you get

8/15

I gave you two different answers for 2b.

Answer:

1. 12cm.

2. 10cm.

3. 18cm.

4. 16cm.

5. 3cm. (or -3 if your question was negative.)

6. 36cm.

7. 8cm.

Explanation:

To find the radius of a circle, simply divide the diameter by 2.

With this being said we can just add on top of the given radius.

Example:

The given radius is 5cm. What is 5cm + 5cm? 10cm.

Thus, getting our answer.

Answer:

1. 12cm.

2. 10cm.

Answer:  (2,-2)

Step-by-step explanation: give me brianlest

Answer:

Using the y=mx+b formula: -6/5

Step-by-step explanation:

6x + 5y = -5

5y = -6x -5

y = -6/5x -1

The slope would be -6/5, meaning the line would travel 5 to the right and 6 down, starting from the coordinate 0, -1.

Step-by-step explanation:

Given Data:

Q) What are the two numbers?

Lets suppose the first number to be x and the second number to be y

The first point states sum of two number which is x + y is less than 2 so our first expression becomes,

[tex]x+y<2[/tex]

The second point states that the if we subtract the second number from the first number which states x - y the difference is greater than 1 so our second expression becomes,

[tex]x-y<1[/tex]

1) The riddle can be represented by a system of inequalities. Write an inequality for each statement.

The inequality for the first statement is

[tex]x+y<2[/tex]

The inequality for the second statement is

[tex]x-y>1\\[/tex]

I assume the second part to the question would be solve for x and y xD

so here goes

2)

If we just simply add both the equations we get the following result:

[tex]x+x+y-y=2+1[/tex]

Just suppose there is an equal to sign instead of less than or greater than

[tex]x+x+y-y=2+1\\2x+0=3\\x=3/2\\x=1.5\\[/tex]

now put the value of x in any one of the two equations I choose equation 1

[tex]x+y=2\\1.5+y=2\\y=2-1.5\\y=0.5[/tex]

Answer:

9 hrs

Step-by-step explanation:

Joshua has already saved $43.50 so you subtract $43.50 from 70 which leaves you with $26.50. Joshua still needs $26.50.

$26.50 divided by $3 per hr is 8.833 repeating. Obviously you can’t work 8.833 hrs so you round it up to 9. So, Joshua has to work for at least 9 hrs more.

Hope this helps :)

Step-by-step explanation:

Coprime numbers:

A Co-prime number is a set of numbers or integers which have only 1 as their common factor.

For eg: (2,3), (11,12), (99,100) and so on; they have 1 as their HCF. The sum of any two coprime numbers is always coprime with the product of the same two coprime numbers. For eg: The sum of 2 and 3 is 5 and the product of 2 and 3 is 6. Hence, 5 and 6 are coprime numbers.

Prime number

A number that can be divided exactly only by itself and 1, for example 7, 17 and 41
