Draw fraction strips to add 1/4 and 1/6 Write an equation.

Answers

Answer:

fraction strips would just be;

1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.

The equation would be as follows:

1/4+1/6 = 3/12+2/12 = 5/12

Answers

Answer:

-1.67 is what I got

Step-by-step explanation:

solved it

The value of f(7) is -1.73 for the function  f(x)=3/(x+2)-√x-3.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

A relation is a function if it has only One y-value for each x-value.

The given function is f(x)=3/(x+2)-√x-3

We need to find the value of f(7)

Replace x with 7 in the given function.

f(7)=3/7+2 - √7-3

f(7)=3/11-√4

=3/11-2

=3-22/11

=-19/11

=-1.73

Hence, the value of f(7) is -1.73 for the function  f(x)=3/(x+2)-√x-3.

Answers

Answer:

Jerry's weight is 36kg and tom's weight is 66kg

Step-by-step explanation:

According to the given condition:

Let,tom's weight =x

Jerry's weight=y

So,

X=2y-6 ---(1)

X+y=102-----(2)

Put value of x from eq 1 in 2

2y-6+y=102

3y-6=102

3y=102+6

3y=108

Y=108/3=36

Jerry's weight is 36.

Put value of y in eq 1

X= 2(36) -6

X=72-6

X=66

So, Tom's weight is 66kg

The number of views on a cat video and a dog video after they're uploaded are represented by the following tables:

Answers

Answer:

Cat video: exponential function

Dog video: linear function

Step-by-step explanation: I did it until I got it right.

The cat video is a exponential function and dog video is a linear function .

What is linear function?

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

What is exponential function?

An exponential function is a mathematical function of the following form:

f ( x ) = . where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

According to the question

The tables for

Cat video

Time(month)      Views

0                           50

5                           313

10                         1950

15                         12210

20                        76300

So, as we can observe that values of views are increasing rapidly which can only be possible if function is exponential .

Dog video

Time(days)      Views

0                           10

6                          452

12                         889

18                         1330

24                        1770

So, as we can observe that values of views are increasing in constant pace which can  be possible if function is linear .

We can plot graph of both the tables to check for the function nature .

Hence, the cat video is a exponential function and dog video is a linear function .
