Answers

Answer:

befor i go im trynna love you baby hopefully e

Step-by-step explanation:

Answer/Step-by-step explanation:

There are 81 Alligators.

The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.

45 ÷ 5 = 9

9 x 9 = 81

5:9 x 9 = 45:81

Cyndi has $55. Her sister has $115. Cyndi saves $10 per week. Her sister saves $6 per week. How many weeks will it
take for Cyndi and her sister to have the same amount of money? Write an equation and solve.

Answers

Answer: It will take 15 weeks for Cyndi and her sister to have the same amount of money.

Step-by-step explanation:

Given: Cyndi has $55. Her sister has $115.

Cyndi saves $10 per week. Her sister saves $6 per week.

Let x= Number of weeks.

Total amount of money Cyndi has = 55+10x            (i)

Total amount of money sister has = 115+6x              (ii)

From (i) and (ii) , we get

[tex]55+10x=115+6x\\\\\Rightarrow\ 10x-6x=115-55\\\\\Rightarrow\ 4x=60\\\\\Rightarrow\ x=\dfrac{60}{4}\\\\\Rightarrow\ x=15[/tex]

Hence, it will take 15 weeks for Cyndi and her sister to have the same amount of money.

Okay, let's get into the formula:

c. = 10 - 5 ⅔

c= 13/3

How do I find a table that represents Y as a function of X

Answers

Answer:

C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2

Step-by-step explanation:

Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.

A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:

- If there are different y values for the same x value

- If the points in order do not create a straight line

- If the points in order do not have a repeating pattern

To identify a function, look for:

- Straight lines

- An actual written function (such as "y =" or "f(x) =")

- A pattern on a table

Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.

Here's an example of a table that represents y as a function of x:

- X: 1  2  3  4  5  

- Y: 3  5  7  9  11

- Pattern: +2 y for every x with constant 1

- X: 3  1   5    4   7  

- Y: 9  3  15  12  21

- Pattern: +3 y for every x with constant 0

Here's an example of a table that doesn't represent y as a function of x:

- X: 1  2  3  4  5  

- Y: 2  5  8  2  4

- Pattern: None

- X: 3 1 5 1 7  

- Y: 1 7 8 9 4

- Pattern: None

what is the effect on the graph of the linear parent function, f (x) = x, when f ( x ) is replaced by f (x +5)

Answers

Answer:

When f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.

Step-by-step explanation:

We know that when we add a number 'a' to the input of the function, it would move the parent function 'a' units to the left.

In other words, the rule is:

f(x + a) will shift the parent function 'a units' to the left.

Given the function

[tex]f(x)=x[/tex]

Thus, when f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.

The effect on the graph of the linear parent function is shown in the attached diagram.

In the graph, the red line is representing the parent function f(x) and the blue line is representing the effect on the graph i.e. f(x+5).

30*100. = 3,000. Divide this by 80 and you get 37.5.

richard and teo have a combined age of 42 richard is 12 years older than twos age how old are richard and teo

Answers

Answer:

teo= 15 years old

richard= 27 years old

Step-by-step explanation:

richard=r

teo=t

r + t=42

t + 12= r

u can use substitution here  

(t+12) + t=42

2t + 12= 42

2t=30

t= 15

to find r, you just do 15 + 12= 27

to check you can do 27 + 15= 42

The age of Richard and Teo will be 27 years and 15 years, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Richard and Teo are 42 years old. Richard is 12 years older than Teo.

Let x be the age of Richard and y be the age of Teo. Then the equation is given as,

x + y = 42         ...1

x = y + 12         ...2

From equations 1 and 2, then we have

y + 12 + y = 42

2y = 30

y = 15

Then the value of the variable 'x' is given as,

x = 15 + 12

x = 27

The age of Richard and Teo will be 27 years and 15 years, respectively.
