Answer:

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

Step-by-step explanation:

We are given that

h(n)=-13n

We have to find the recursive formula of h(n).

Substitute n=1

h(1)=-13

n=2

h(2)=-13-13=-26=h(1)-13

n=3

h(3)=-13(3)=-39=-26-13=h(2)-13

h(4)=-13(4)=-52=-39-13=h(3)-13

:

:

:

h(n)=h(n-1)-13

Therefore, the recursive formula is given by

h(1)=-13

h(n)=h(n-1)-13, n\geq 2

Is (4,9) a solution to the equation 3(x+2) = y ?
Mrac [35]

Answer:

(4, 9) is not a solution to 3(x + 2) = y.

Step-by-step explanation:

3(x + 2) = y

Substitute (4, 9) into the equation.

3(4 + 2) = 9

Add the inside of the parenthesis.

3(6) = 9

Multiply.

The expression 148 – 24d gives the number of pizzas a store has in stock, where d is the number of days. How many pizzas will th
Feliz [49]

Explanation

A function is defined as a relation between a set of inputs having one output each,in this case our independent variable is the number of days( d) and the dependent variable would be the number of pizzas

so

Step 1

let the function

\begin{gathered} P=148-24d \\ where\text{ P is the number of pizzas } \\ and\text{ d is the number of days} \end{gathered}

therefore, to know the number of pizzas are in the stock after 5 days we need to evaluate the equation for d=3

so

\begin{gathered} P=148-24d \\ let\text{ d=5 and evaluate} \\ P=148-24(5) \\ P=148-120=28 \\ P=28 \end{gathered}

so, after five day there willbe 28 pizzas in stock

I hope this helpsyou

Which table shows a proportional relationship between x and y? x 2 3 5 6 y 3 4 7 9 x 4 6 8 10 y 6 8 10 12 x 1 5 8 10 y 15 75 120
AysviL [449]

Answer:

Only the 3rd table shows a proportional relation between x and y.

Step-by-step explanation:

The first table is  

x 2 3 5 6  

y 3 4 7 9

Here y is not increasing in uniform rate with x. So, the relation is not proportional.

The second table is  

x 4 6 8 10  

y 6 8 10 12

Here y is increasing in uniform rate with x, but at x = 0, y ≠ 0, Hence, the relationship is not proportional.

The third table is  

x 1 5 8 10  

y 15 75 120 150

Here, y is increasing in uniform rate with x, and  at x = 0, y = 0, Hence, the relationship is proportional.

The fourth table shows

x 3 9 10 15  

y 1 3 4 5

Here also y is not increasing in uniform rate with x. So, the relation is not proportional.

Therefore, only the 3rd table shows a proportional relation between x and y. (Answer)

If Zach has 4 times as many dimes as quarters and they have a combined value of 455 cents, how many of each coins does he have?
aliya0001 [1]

<u>ANSWER: </u>

Zach has 28 dimes and 7 quarters.

<u>SOLUTION: </u>

Given, Zach has 4 times as many dimes as quarters  

And they have a combined value of 455 cents,  

We need to find how many of each coins does he have?

Let, the number of dimes be x and number of quarters be y.

Then, x = 4y → (1)

Total combined value = 455 cents

x(value of one dime) + y(value of one quarter) = 455 cents

x(10 cents) + x(25 cents) = 455 cents

10x + 25y = 455 → (2)

Now, substitute (1) in (2)

10(4y) + 25y = 455

40x + 25y = 455

65y = 455

y = 7

substitute y value in (1)

x = 4(7)  = 28

Hence, zach has 28 dimes and 7 quarters.
