Answer:

a = - 6, b = 13

Step-by-step explanation:

Given f(1) = 7 , that is f(x) = 7 when x = 1

f(3) = - 5 , that is f(x) = - 5 when x = 3

Substitute these values into f(x) = ax + b

a + b = 7 → (1)

3a + b = - 5 → (2)

Subtract (1) from (2) term by term to eliminate b

(3a - a) + (b - b) = - 5 - 7

2a = - 12 ( divide both sides by 2 )

a = - 6

Substitute a = - 6 into either of the 2 equations and solve for b

Substituting into (1)

- 6 + b = 7 ( add 6 to both sides )

b = 13

Answer:

Step-by-step explanation:

The amount A is said to vary inversely with n, so the equation relating the two is ...

  A = k/n

The value of k can be found by multiplying this equation by n:

  k = nA

Using values from the first line of the table, we find ...

  k = (1)(25000) = 25000

So the relation we need to use to fill the table is ...

  A = 25000/n

The filled table is attached.

As we saw in part 1, the product A*n is the constant of proportionality. It is a constant.

Answer:

The Y-intercept is 4 or (0,4) in a plot

Step-by-step explanation:

To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13

(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)

Now continue until you reach 0 in the "x"

4 to 3 and 13 to 10

3 to 2 and 10 to 7

2 to 1 and 7 to 4

So the y-intercept is 4 or (0,4) in a plot

Answer:

$42.00

Step-by-step explanation:

Answer:

26.25

Step-by-step explanation:

If 4 slices are 10.50 $ then 8 are 21 $.We need 2 more to reach 10 slices and half of 4 is 2 so half of 10.50 is 5.25 so add 21 $ + 5.25 $ = 26.25.

Step-by-step explanation:

Answer:

f(x) = x² - 8x + 12

Step-by-step explanation:

Given the zeros are x = 2 and x = 6 then the corresponding factors are

(x - 2) and (x - 6)

The function is then the product of its factors

f(x) = (x - 2)(x - 6) ← expand using FOIL

f(x) = x² - 8x + 12

Answer:

$38.40

Step-by-step explanation:

20% of $48 is 9.60

48- 9.60= 38.40

Answer:

$38.40

Step-by-step explanation:

1. convert the percentage into a decimal by dividing x/100.

         20/100 =  0.2

2. multiply by the original price.

         0.2 * 48 = 9.6

3. subtract the discount.

         $48 - $9.60 = $38.40

Answer:

one blue candle. 1/12 probability.

Step-by-step explanation:

if they are as likely as not to select a green candle, then there are 6 green ones. so now we have accounted for 11 if I am right, so only one can be blue

It is equally likely as not that the customer will select a blue candle.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Let the number of green candles on the tray be G, and the number of blue candles be B.

We know that there are 12 candles in total on the tray, so:

G + B = 12 (total number of green and blue candles is 12)

G/(G+B) = 1/2 (as the probability of selecting a green candle is equal to the probability of selecting a non-green candle)

We can use these two equations to solve for G and B:

G + B = 12

G = (12 - B)

Substituting into the second equation:

(12 - B) / (12 - B + B) = 1/2

(12 - B) / 12 = 1/2

12 - B = 6

B = 6

So there are 6 blue candles on the tray.

Since there are 12 candles in total, and 6 of them are blue, the probability of selecting a blue candle at random is:

P(selecting blue) = B / (G + B) = 6 / 12 = 1/2

Therefore,

It is equally likely as not that the customer will select a blue candle.

This means that the probability of selecting a blue candle is 50-50, which is neither impossible nor certain, but rather equally likely as selecting a green candle.

Answer:

x = 7

Step-by-step explanation:

The Triangle Sum Theorem tells us that the sum of the measures of a triangle's interior angles is 180. Using this information, we can make an equation to solve for x.

82 + 9x - 6 + 6x - 1 = 180

75 + 15x = 180    (Combine like terms)

15x = 105            (Subtract 75 from both sides)

x = 7                    (Divide both sides by 15)

We can plug the value of x back into the equation to make sure of this answer.
