8-(2-3)-1=6-(-2)

Answer:

x = 10

Step-by-step explanation:

Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.

Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30

                         = 18

x + 8 = 18

x = 18 - 8

x = 10

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers.

Each bouquet would contain: 3 roses, 1 daise and 5 tulips

Step-by-step explanation:

Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?

We solve the above question using Greatest Common Factor method.

We find the factors of 27, 9 and 45

The greatest common factor is the highest factor common to these 3 number

Hence:

The factors of 9 are: 1, 3, 9

The factors of 27 are: 1, 3, 9, 27

The factors of 45 are: 1, 3, 5, 9, 15, 45

Then the greatest common factor is 9.

Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers

Each bouquet would contain

For 27 roses = 27/9 bouquet = 3 roses

For 9 daisies = 9 daisies/9 bouquet = 1 daisies

For 45 tulips = 45 tulips/9 bouquet = 5 tulips

Answer:

coordinate plane?

Step-by-step explanation:

.

Answer:

In polar coordinates the origin is often called the pole. Because we aren't actually moving away from the origin/pole we know that r=0 . However, we can still rotate around the system by any angle we want and so the coordinates of the origin/pole are (0,θ)

Answer:

0.375 seconds

Step-by-step explanation:

In simple terms, to find the time it took to reach the ground, we need to find t from the equation.

If we differentiate h with respect to t we will get the velocity with which the fireworks is moving at.

[tex]h(t) = - 16t^2 + 4t.\\dh/dt =-32t +4[/tex]

We can now equate this to its velocity and solve for t

10 = -32t +4

t = 0.1875 ( time cannot be negative in value, so we ignore the negative sign)

Therefore, the time it took the fireworks to reach the ground is = 2 x 0.1875= 0.375 seconds.

(We need to account for the fact that the fireworks went up and came down)

Answer:

Let y=34 and x=3

Step-by-step explanation:

y = 8x + 10

34 = 8 (3) + 10

34 = 24 + 10

34 = 34

Hence,3 and 34 satisfies this equation.

Step-by-step explanation:

Answer:

Answers are in bold

Step-by-step explanation:

Part 1A

Use the Zero Product Property to find the x-intercepts:

0=-(x+4)(x-1)

0=(x+4)(x-1)

0=(x+4)

-4=x

x=-4

0=(x-1)

1=x

x=1

So the x-intercepts are x=-4 and x=1 which is also (-4,0) and (1,0)

For the y-intercepts, plug in x=0:

f(x)=-(0+4)(0-1)

f(x)=(-4)(-1)

f(x)=4

So the y-intercept is y=4 which is also (0,4)

Part 1B

In general, the axis of symmetry is equal to x=h in the equation y=(x-h)^2+k

For a parabola, the axis of symmetry is equal to x=-b/2a, so we expand the given equation and then plug in the values of "a" and "b" to get the axis of symmetry:

f(x)=-(x+4)(x-1)

f(x)=-(x^2+3x-4)

f(x)=-x^2-3x+4

So now we know a=-1 and b=-3, therefore we can plug them in:

x=-b/2a

x=-(-3)/2(-1)

x=3/-2

x=-3/2

x=-1.5

So the equation of the axis of symmetry is x=-1.5

Part 1C

We'll use the equation x=-b/2a to get the x-coordinate for the vertex (which we already know is x=-1.5), then plug in that value of x in the original equation to get the y-coordinate for the vertex:

f(x)=-(-1.5+4)(-1.5+1)

f(x)=-(2.5)(-0.5)

f(x)=-(-1.25)

f(x)=1.25 <-- y-coordinate

So the coordinates of the vertex are (-1.5,1.25)

Step-by-step explanation:

Part 2

Organize your data and find the rate of change.

I’m sorry i didn’t know how to make a table so i just did this  

Person number 1- Left foot is 9 inches Forearm is 8.5 inches

Person number 2- Left foot is 7.5 inches Forearm is 7 inches

Person number 3- Left foot  is 11 inches Forearm is 10.5 inches

Person number 4- Left foot: is 10 inches Forearm is 9.5 inches

Person number 5- Left foot  is 6 inches Forearm is 5.5 inches

The rate of change equals y=x-0.5

I believe that it's a function because there is a relationship between 2 variables.

Part 3

Compare rates of change.

The equation below can be used to find the length of a foot or forearm when you know one or the other.  

(length of the foot) = 0.860 • (length of the forearm) + 3.302

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to

y = 0.860x + 3.302.  

Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

i don’t know how to type all my formulas and work so i'm just going to say the answer i got the rate of change = 0.86x or y=0.86x+3.302  

What is the rate of change of the equation from Part A?

For Part A i got y=x-0.5 and that part A has the greater rate of change.

Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?

Well, the values have to be different because there are different rates of change and different linear coefficients; and also each input value will result in a different output value because they all have different parameters as well.  

Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.

Yes, it is a function because each input from part A fits well together with the output on the other set, which matches the definition of a function.

Answer:

The amount of the money earned left for the band to split is $357.5

Step-by-step explanation:

The amount the band earned for playing at the concert = $550.00

The percentage of the money earned taken by the manager = 15%

The percentage of the money earned the band is donating to charity = 20%

The amount of the money earned the manager takes = 15/100 × 550 = 82.5

∴ The amount of the money earned the manager takes = $82.5

The amount of the money earned that is donated to charity = 20/100 × 550 = 110

∴ The amount of the money earned that is donated to charity = $110

The amount of the money earned left for the band to split = $550 - $82.5 - $110 = $357.5.

Answer:

13,0

Step-by-step explanation:

12=3(x-9)

divide both sides by three

Answer:

x-intercept: (13,0)

y-intercept: (0,-39)

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y  and solve for  x .

To find the y-intercept, substitute in  0  for  x  and solve for  y .

Answer:

it should be an 8

Step-by-step explanation:

The initial value in this question y = 8x+6 will be 8 .

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The equation is given as;

y = 8x+6

We can see that the equation contains two terms that are 8x and 6.

The initial value is the first number of the first term in the equation.

Here, the first term is 8x.

Hence, the initial value in this question y = 8x+6 will be 8 .
