Good luck on your quiz :)

Graph (a) represents an exponential decay.

Here, two graph are shown and we have to check which represent exponential decay.

What is exponential decay?

Exponential decay occurs when a quantity decreases by the same factor over equal intervals of time.

Now,

From the graph, we have

In graph (a), as x increases the function decreases.

Hence this graph shows exponential decay.

In graph (b), as x increases the function increases.

So, Graph (a) represents an exponential decay.

3m+6=24

3m=18

m=6

So mike traveled 6 miles by taxi.

We know that the taxi driver chargers $3 per mile, so we say M is the mile variable, and for every M there is $3. So 3m+6 (initial fee) is the first part of the formula.

We set 3m+6=24 (24 being the total amount the taxi driver is charging)

Answer:

What is the fraction compared to?

Answer:

1) k = -10

2) n = -4

3) a = -9

Step-by-step explanation:

1) -4 = 6 + k

*we want to get k alone, so we will subtract 6 from both sides*

-4 = 6 + k

-6   -6

-10 = k

*in order to check this, we will plug the value we found for k, -10, into the original equation*

-4 = 6 + k

-4 = 6 + (-10)

-4 = -4

*this is correct because -4 = -4, so that is how we check*

2) -4n = 16

*we want n alone, we must divide by -4 on both sides*

-4n = 16

n = -4

*in order to check this, we plug what we found for n, -4, into the original equation*

-4n = 16

-4(-4) = 16

*a negative multiplied by a negative is a positive!*

16 = 16

*this is correct because 16 = 16*

3) 3/4a = -12

*we want a alone, so we will multiply by the negative reciprocal to get rid of the fraction on the left side*

a = -12 times 3/4

a = -9

*in order to check this, we will plug what we found for a, 9, into the original equation*

3/4a = -12

3/4 (-9) = -12

-12 = -12

*this is correct because -12 = -12*

Step-by-step explanation:

Trapezoid ABCD was dilated to create trapezoid A'B'C'D'.

Scale factor is 1/2 according to the coordinates.

The length of side AD is 8 units.

The length of side A'D' is 4 units.

The image is larger than the pre-image.

Sides CD and C'D' both have the same slope, 2.

Slopes of CD and C'D' are same: m = (0 - 4)/(4 - 2) = -4/2 = -2

The scale factor is One-half.

Answer:100 mph

Step-by-step explanation: it’s always distance divided by time. lol

The train travels to a distance of 75 miles in 0.75 hours, then the speed of the train will be equal to 100 miles per hour.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data mentioned in the question,

Distance (d) traveled by train = 75 miles

Time (t) taken by train to travel the distance = 0.75 hours

Then, use the equation of speed (s),

[tex]Speed =\frac{Distance}{Time}[/tex]

s = 75/0.75

s = 100 miles per hour.

Answer: See Explanation

Step-by-step explanation:

Your question isn't well analysed but I guess that you want to calculate when both of them will have same number of users.

Let the number of days that both of them will have thesame number of competitors be x.

Therefore,

150 + 25x = 600 + 10x

25x - 10x = 600 - 150

15x = 450

x = 450/15

x = 30

They'll have same competitors by the 30th day.

The number of competitors will be:

= 150 + 25x

= 150 + 25(30)

= 150 + 750

= 900

Answer:

21.4% of 855=182.97

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 855 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 855 is 100%, so we can write it down as 855=100%.

4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.

5. Now we have two simple equations:

1) 855=100%

2) x=21.4%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

855/x=100%/21.4%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 21.4% of 855

855/x=100/21.4

(855/x)*x=(100/21.4)*x       - we multiply both sides of the equation by x

855=4.67289719626*x       - we divide both sides of the equation by (4.67289719626) to get x

855/4.67289719626=x

182.97=x

x=182.97

now we have:

21.4% of 855=182.97

Answer: 24 raisins

Step-by-step explanation:

30% of the mixture are raisins which means that 70% are peanuts.

That 70% translates to 56 peanuts.

The total of the mixture is therefore:

= 56 / 70%

= 80 mixture of raisins and peanuts

Raisins are 30%:

= 30% * 80

= 24 raisins

Step-by-step explanation:

Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.

So, 1) AB/BC = AJ/JI

2.5/2.25 = AJ/1.8

AJ = 2.5* 1.8 / 2.25

AJ = 2

2) BC/CD = JI / IH

2.25/CD = 1.8/1.2

CD = 2.25 * 1.2 / 1.8

CD = 1.5

3) CD/DE = IH/HG

1.5/3.5 = 1.2 / HG

HG = 1.2 * 3.5 / 1.5

HG = 2.8

4) For GF, we should use "Pythagoras Theorem"

h² = a² + b²

GF² = 6.5² - 6²

GF² = 42.25 - 36

GF = √6.25

GF = 2.5

5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2

P = 26.55

6) Area = 1/2 * b * h

A = 1/2 * 9.65 * 10.3

A = 49.70

no ablo inglés solo español perdón por no responderte

Step-by-step explanation:

m(x + n) = n

mx + mn = n

mx = n - mn

x = (n - mn)/m

x(a + b) = b(c - x)

ax + bx = bc - bx

ax + bx + bx = bc

x(a + b + b) = bc

x(a + 2b) = bc

x = bc/(a + 2b)

mx = n(m + x)

mx = mn+ nx

mx - nx = mn

x(m - n) = mn
