Molly is planting the flowers using the proportional relationship of 18 pink flowers to 12 white flowers per row.

Find the ratio of pink flowers per white flower per row.

Molly is planting a ratio of
pink to white flowers.

Answer:

not very good

Step-by-step explanation:

the correlation should be almost 1  to be a good representation of the data. 0.82 isn't very close.  This would be a pretty "rough" approximation at best.  Maybe that's all that's needed but usually something close to 1.. like 0.99 is needed.

Answer:

After 11 weeks, Darnell′s savings account will have a total of $8,360.

Step-by-step explanation:

The data provided is as follows:

   n:    1        2       3        4

f (n): 260   360   460   560  

Consider the data for f (n).

The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.

The nth term of an arithmetic sequence is:

[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]

Compute the value of f (11) as follows:

[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]

        [tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]

Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

Answer:

93.6 becasue there are 12 donuts in a dozen. So you multiply 12 by 7.80.

Answer:  Oldi gives the best value of money.

Step-by-step explanation:

Lidal's deal : 9 rolls for £3.51

Oldi's deal : 4 rolls for  £1.52

Cost per roll = [tex]\dfrac{\text{total cost}}{\text{Number of rolls}}[/tex]

So,

For Lidal, Cost per roll = [tex]\pounds\dfrac{3.51}{9}=\pounds0.39[/tex]

For Oldi', Cost per roll = [tex]\pounds\dfrac{1.52}{4}=\pounds0.38[/tex]

Clearly,  [tex]\pounds 0.39> \pounds 0.38[/tex]

Hence, Oldi gives the best value of money.

Answer:  -2 • (4x2from4 + 5x + 1)

3.2    Factoring    4x2from4 + 5x + 1

Answer:

-2

Step-by-step explanation:

Sorry if i'm wrong

Standard form:

Ax + By = C

First make it into slope-intercept form first:

y = mx + b

Find b by substituting the given to their respective positions:

-2 = 3(6) + b

-2 = 18 + b

-2 - 18 = b

-20 = b

Now the complete version is:

y = 3x - 20

Arrange the equation:

y = 3x - 20

-3x + y = -20

Easy :)

Answer:

19.47

Step-by-step explanation:

F + 3!=0, g = (F^2 + 5 F + 20)/(9 (F + 3)), x = -14/(F + 3)

Step-by-step explanation:

Answer:

1. add 14 to both sides

b/2 = 8E + 14

2. multiply both sides by 2

b = (8E + 14) x 2

3. regroup terms

b = 2(8E + 14)

Hope this helped :)

Polynomial Roots

If x=a is a root of f(x), then f(a)=0

We will test the following functions to check if a=2 is a root.

[tex]h(2)=8-2^3=8-8=0[/tex]

Thus m=2 is a root of h

[tex]f(2)=2^3-2\cdot 2^2+2[/tex]

[tex]f(2)=8-2\cdot 4+2=8-8+2=2[/tex]

Thus g=2 is not a root of f

[tex]f(2) = 2^3 - 4\cdot 2^2 + 2 + 6[/tex]

[tex]f(2) = 8-16+8=0[/tex]

Thus a=2 is a root of f

[tex]f(2)=2^3 - 2^2 - 4[/tex]

[tex]f(2)=8 - 4 - 4=0[/tex]

Thus x=2 is a root of f

THIS IS CORRECT

Answer:

The ratio is 1:4

Step-by-step explanation:

For every minute of talking, it costs him 4 cents, and so on.

Answer:

option C, x=1

Step-by-step explanation:

[tex]2^{9x-3} = 8^{3-x}[/tex]

[tex]2^{9x-3} = (2^3)^{3-x}[/tex]

[tex]2^{9x-3} = 2^{9-3x}[/tex]

cut 2 from LHS and RHS  you will get,

9x-3 = 9-3x

9x + 3x = 9 + 3

12x = 12

x = 12/12

x = 1

therefore, option C is the correct option

hope it helps you!

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{x = 1}}}}[/tex]

Option C is correct.

Step-by-step explanation:

[tex] \text{First ,\: let's \: know \: about \: exponential \: equation} : [/tex]

An equation in which variables appears as an exponent of a base is known as exponential equation. The following axioms are useful while solving the exponential equations :

Thus , while solving an exponential equation, we should simplify the equation till the equation is obtained in the form [tex] \sf{ {a}^{x} = {a}^{b}} [/tex] or aˣ = 1 .

Now, let's start to solve :

[tex] \sf{ {2}^{(9x - 3)} = {8}^{( 3 - x)}} [/tex]

➸ [tex] \sf{ {2}^{9x - 3} = {2}^{3(3 - x)} }[/tex]

➸ [tex] \sf{ {2}^{9x - 3} = {2}^{9 - 3x}} [/tex]

➸ [tex] \sf{ \cancel{2} ^{ \: 9x - 3} = \cancel{2} ^{ \: 9 - 3x} }[/tex]

➸ [tex] \sf{9x - 3 = 9 - 3x}[/tex]

➸ [tex] \sf{9x + 3x = 9 + 3}[/tex]

➸ [tex] \sf{12x = 12}[/tex]

➸ [tex] \sf{ \frac{12x}{12} = \frac{12}{12}} [/tex]

➸ [tex] \boxed{ \sf{x = 1}}[/tex]

The value of x is 1 .

Hope I helped!

Answer:

7.639

Step-by-step explanation:

7.639 rounds to 7.64 which is the closest on I could find to 7.62.

Answer:

 I think the answer is 7.636

Step-by-step explanation:

Answer:

(-4, -17), (-3, -10), (-2,5), (-1,2)

All the coordinates are represent linear function.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The coordinates are,

⇒ (-4, -12), (-3,-10), (-2, -8), (-1,-6)

⇒ (-4, -17), (-3, -10), (-2,5), (-1,2)

⇒ (1, -7), (2, -10), (3, -13), (4, -16)

⇒ (1, 1), (2, 4), (3, 7), (4, 10)

Now,

We know that;

A relation between a set of inputs having exactly one output each is called a linear function.

Clearly, All the coordinate have exactly one output for every input.
