Answer:

-16

Step-by-step explanation:

Given the sequence:

b(n)=b(n−1)−7, where b(1)=−2

b(2)=b(2−1)−7

=b(1)−7

=-2-7

b(2)=-9

Therefore, the 3rd term of the sequence

b(3)=b(3−1)−7

=b(2)-7   (Recall b(2)=-9 from above)

=-9-7

b(3)=-16

The 3rd term of the sequence is -16.

Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
Oxana [17]

Answer:

D. h(x)=-3x+4

Step-by-step explanation:

we are given

f(x)=3x

Firstly, it is reflected over x-axis

we know that for reflection about x-axis , we can replace y as -y

we get

g(x)=-f(x)

g(x)=-3x

now, it is vertical shift up by 4 units

so, we can add 4 to y-value

we get

h(x)=g(x)+4

h(x)=-3x+4

At a school fair 70% of the people are under 16 years old. One third of the people remaining are teachers. If there are 21 teach
Tamiku [17]
In the fairest school 70% are below 16 years old 1/3 are teachers which is equals to = 21 Let’s start solving: => 1/3 of 100% => 100 / 3 = 33.33% thus 33.33% = 21 => 21 x 3 = 63, is the total number of people in the school. Let’s try solving the number of people below 16 years old Have you notice that you are asking for a 70% of students but there are already 33.33% of teacher. Thus your given problem is not right already. => 100% - 33.33% = 66.67% that’s the only remaining percentage and not 70% => 63 * .6667 = 42.0021 Thus, there are around 42 people who are 16 years old younger.

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50
Vsevolod [243]

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

3.00 + 0.50 m = 9.50

Where m is the number of miles.

The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.

So, the correct statements are:

  • The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
  • Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Feel free to ask for more if needed or if you did not understand something.
