The answer to Number 9 is D and the answer to number 10 is D because in number 9, City P is above 0 and City R is a negative number and below 0. In number 10, Point A is at -20 and Point B is 5 less. That would get you the equation -20-5. -20-5 = -25. On a number line, -25 is less than -20 and would be on the left side of Point A. Hope this helps!

Answer: B

Step-by-step explanation:

y = azaleas

x = lilies

6y + 5x =196 total cost

y + x = 36 total number of items

y = 36 – x

6(36 -x ) +5x =196

216 – 6x + 5x = 196

-x = 196 – 216

-x = -20

Divide by -1

X = 20 lilies

Plug into y equation

Y = 36 – 20

Y= 16 azaleas

To check

6(16) + 5(20) = 196

96 + 100 = 196

The answer is b 16 because you add the variables into the end of the numbers to identify you answer

Answer:

Ф = 10°

Step-by-step explanation:

Regarding arc length, s:  s = r·Ф, where Ф is the central angle in radians and r is the radius.

We need to find the central angle, Ф, in this problem.

We know that C = circumference = 6, and that this leads to r = 6/π.

Substituting 6/π for r and 1/3 for s in Ф = s / r, we get:

Ф in radians = 1/3  /  (6/π), or  Ф = π/18 rad.    

                                                                           π         180°

Converting this into degrees, we multiply    ------ by ----------

                                                                           18        π rad

obtaining:  Ф = 10°

ANSWER

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

EXPLANATION

The given function is:

[tex]f(x) = {x}^{2} [/tex]

The function g(x) is a vertical compression of f(x).

This implies that:

[tex]g(x)=a\bullet f(x)[/tex]

[tex]g(x)=a\bullet {x}^{2} [/tex]

The function g(x) goes through (1,9).

[tex]g(1)=9[/tex]

[tex]a\bullet {(1)}^{2} = 9[/tex]

[tex]a = 9[/tex]

Hence the function is:

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

This can be rewritten as:

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

The correct choice is A.

Answer: g(x)=(3x)^2

In the TRUE column:

- 0.65 pound of almonds costs $2.20

- the price per pound of almonds equals $2.20/0.65

That's basically the same information, presented 2 different ways, and they match the info presented in the graph.

In the FALSE column:

- 2.2 pounds of almonds cost $0.65 (nope, wrong numbers)

- Almonds cost $0.65 per pound (nope, they cost $3.38 per pound)

In the CANNOT BE DETERMINED column:

- Each bag of almonds weighs 2.2 pounds. (Cannot be verified, but it's highly unlikely since the price point on the graph is at 0.65 pounds)

Answer:

Step-by-step explanation:

well let break it down

you have 1/10

you need 4 and 3/10

that can be changed to 43/10 because you need 4 WHOLE or 40/10 (40/10 = 4)

if you can pour 1/10 and you need a total of 43/10, you'd need to use 43 of the 1/10 measuring cups

To measure out 4 3/10 cups of flour using only a 1/10 measuring cup, you would need to fill the 1/10 measuring cup 43 times.

To determine how many 1/10 cups are needed to measure out 4 3/10 cups of flour, start by converting the desired amount into tenths.

4 3/10 cups can be thought of as 4 cups plus 3/10 of a cup, which is equivalent to 40/10 cups plus 3/10 cups, giving us 43/10 cups in total.

Since you only have a 1/10 measuring cup, you would need to use this cup a total of 43 times to get 43/10 cups of flour. Therefore, you would need to use the 1/10 measuring cup 43 times to obtain the necessary flour for the recipe.

Hello There!

Slope: 1

Equation: y = x - 2

Let's start by finding the slope. To find the slope of a given equation, subtract the y values over the x values.

y1 - y2 / x1 - x2 ⇒ 3 - 0 / 1 - - 2 ⇒ 3 / 3 ⇒ 1

This means we have a slope value of 1.

Now, to find an equation. We will find the equation in slope intercept form, or y = mx + b. (In this case, m = the slope and b = the y-intercept, and x and y equal your x and y values fro a given point.)

To get the equation, we need to find the value of b, or the y intercept. To do this, we need to plug in the values we know into the equation.

we know m is the slope, and we know the slope is one so we can place that into the equation. We also know the points (0,-2) (3,1). We can place one of them into the equation for the values x and y.

1 = 1(3) + b

Now, simplify.

1 = 1(3) + b

1 = 3 + b

-2 = b

So, our y intercept is -2, we can plug that into the equation, making our final equation y = x - 2. We don't need to put y = 1x for the slope since multiplying something by 1 is doesn't change the number.

I hope this helps! I know my explanation might have been kind of confusing so if you need more help let me know in the comments !

Answer:

y = x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1+2}{3-0}[/tex] = [tex]\frac{3}{3}[/tex] = 1

Note the line crosses the y- axis at (0, - 2) ⇒ c = - 2

y = x - 2 ← equation of line

Answer:

Step-by-step explanation:

The equation of a circle is:

(x - h)² + (y - k)² = r²

where (h, k) is the center and r is the radius.

Answer:

There were 10 people in team one.

Step-by-step explanation:

Let x= team one.

Let y= team two

Because there four times less people in team one than in two we know that x=(1/4)y

After 6 people quit and 12 people transfer from team two, the two teams become equal. Therefore, x + 12 = y - 6 - 12.

You can then insert the initial equation for x into the second equation and know that there were 10 people in team one and 40 people in team two.

The process to solve this problem involves setting up an equation based on the given information and solving for x, which represents the original number of people on team one. The numerical answer is 10 people.

Let's denote the original number of people in team one as 'x'. Therefore, since team two had 4 times more people than team one, team two originally had '4x' people. The problem then tells us that 12 people were transferred from team two to team one and 6 people quit team two. This means that team two now has '4x - 12 - 6' people and team one has 'x + 12' people. Because both teams are equal in size after these changes, we can set these two expressions equal to each other. So, 'x + 12' is equal to '4x - 18'. Solving this equation for 'x' gives us x = 10.

So originally, team one had 10 people.

the answer is C.  210 sq. cm

Step-by-step explanation:

Find the area of the triangle

The area of one of the triangular faces can be found by using the formula below.  

a = 1/2 bh

a = 1/2 (5 cm) (12 cm)

a = 30 sq. cm

Since there are two triangular faces, multiply the area of one triangular face by 2. The area of two triangular faces is 60 cm2.

Next, find the area of each of the three rectangular faces using the formula, area = lw.

1st rectangle

a = lw

a =  (5 cm) (5 cm)

a = 25 sq. cm

2nd rectangle

a = lw

a = (5 cm) (12 cm)

a = 60 sq. cm

3rd rectangle

a = lw

a = (5 cm) (13 cm)

a - 65 sq. cm

Add the three rectangle areas to find a total of 150 sq. cm.

To find the surface area of the triangular prism, add the area of the two triangular faces to the area of the three rectangular faces.

60 sq. cm + 150 sq. cm = 210 sq. cm

Answer: D

Step-by-step explanation:

if the slope is 7, mx + b =y the slope is m. that’s the only one that makes sense. hope this helps!

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m = 7, thus

y = 7x + c ← is the partial equation

To find c substitute (1, 2) into the partial equation

2 = 7 + c ⇒ c = 2 - 7 = - 5

y = 7x - 5 → D

The approximate price of a pint of veggies is $1.75

Step-by-step explanation:

if v represents the cost of a pint of cut vegetables and f represents the cost of a pint of cut fruits then the equation that models the cost of "v" vegetables and "f" fruits is:

[tex]hv + 2.85f = z[/tex]

Where z represents the total cost of buying "v" vegetables and a "f" pints of fruits.

h represents the cost  of a pint of cut vegetables .

We know that the cost "z" of 5 vegetables pints and 7 fruits pints is $ 28.70

So:

[tex]v = 5\\f = 7\\z = 28.70[/tex]

We substitute these values ​​into the equation and solve for h.

[tex]h(5) + 2.85(7) = 28.70\\\\5h=28.70-2.85(7)\\\\5h=28.70-19.95\\\\5h=28.70-19.95\\\\h=\frac{8.75}{5}\\\\h=\$\ 1.75[/tex]

Answer:

Step-by-step explanation:

We have the logistic growth function [tex]f(t)=\frac{25,000}{1+8.25e^{-0.076t}}[/tex]  and we want to find the time when the population will reach 20,000, to do it we just need to replace [tex]f(x)[/tex] with 20,000 and solve for [tex]t[/tex]:

[tex]f(t)=\frac{25,000}{1+8.25e^{-0.076t}}[/tex]

[tex]20,000=\frac{25,000}{1+8.25e^{-0.076t}}[/tex]

Divide both sides by 25,000

[tex]\frac{20,000}{25,000} =\frac{1}{1+8.25e^{-0.076t}}[/tex]

[tex]0.8=\frac{1}{1+8.25e^{-0.076t}}[/tex]

Multiply both sides by [tex]1+8.25e^{-0.076t}[/tex] and divide  them by 0.8

[tex]1+8.25e^{-0.076t}=1.25[/tex]

Subtract 1 from both sides

[tex]8.25e^{-0.076t}=0.25[/tex]

Divide both sides by 8.25

[tex]e^{-0.076t}=\frac{0.25}{8.25}[/tex]

[tex]e^{-0.076t}=\frac{1}{33}[/tex]

Take natural logarithm to both sides

[tex]ln(e^{-0.076t})=ln(\frac{1}{33} )[/tex]

[tex]-0.076t=ln(\frac{1}{33} )[/tex]

Divide both sides by -0.076

[tex]t=\frac{ln(\frac{1}{33} )}{-0.076}[/tex]

[tex]t[/tex] ≈ 46

We can conclude that the population will reach 20,000 after 46 years.
