Is the following a function?
{(1, -2), (-2, 0), (-1, 2), (1,3)}

Answers

Answer 1
it is not a function. A function is a relation in which no two ordered pairs have the same input (or x-values) and different outputs (y-values).

You need to determine whether every first element (or input) correspond with EXACTLY ONE second element (or output).

in this case, the input value of 1 goes with two output values, -2 and 3.  

It only takes one input value to associate with more than one output value to be invalid as a function.

Therefore, the given relation is not a function.

Two fifth of pupils in a standard 7 class were girls.There were 27 boys in the class. ( a) how many girls were there. (b) how many peoples were there in the standard 7 class​

Answers

Answer:

a. 18

b. 45

Step-by-step explanation:

The question states that 2/5 of the class are girls which means 3/5 are boys:

[tex]\frac{3}{5} = 27[/tex]

Divide this value by 3 to get the value of [tex]\frac{1}{5}[/tex]:

27 ÷ 3 = 9

Multiply this by 5 to find [tex]\frac{5}{5}[/tex], the total pupils in the class:

9 x 5 = 45

As the number of girls is [tex]\frac{2}{5}[/tex] of the total pupils:

9 x 2 = 18

So there are 18 girls in the class which has a total pupil size of 45.

Hope this helps!

Step-by-step explanation:

according to question of are girls than are boys

so let the number of girls be x

so,

of x = 27

x = 27 × 5/3 = 9×5 = 45

x = 45

a ) 45 - 27 = 18

than no. of girls is 18.

b) thier are 45 students in total.

Rosemarie has 16 grandchildren and they will each get 0.50 cents

Answer:

a. Rosemarie has 16 grandchildren.

b. Each grandchild would receive $0.50 or 50 cents.

Step-by-step explanation:

a. There are 4 sons, and each son has 4 children.

Son 1: 4 children

Son 2: 4 children

Son 3: 4 children

Son 4: 4 children

So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16

Rosemarie has 16 grandchildren.

b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).

And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50

Each grandchild would receive $0.50 or 50 cents.

We move all terms to the left:

0.3(y-2)+0.4y-(0.3y-0.6)=0

We add all the numbers together, and all the variables

0.4y+0.3(y-2)-(0.3y-0.6)=0

We multiply parentheses

0.4y+0.3y-(0.3y-0.6)-0.6=0

We get rid of parentheses

0.4y+0.3y-0.3y+0.6-0.6=0

We add all the numbers together, and all the variables

Answers

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.

So, [tex]1000/16=\boxed{62.5}[/tex].

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.

So, [tex]400/8=\boxed{50}[/tex]

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.

So, [tex]300/4=\boxed{75}[/tex].

4)

The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

Hope this helps you!!!

The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.

What are the roots of an equation?

Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.

For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.

The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.

Given the roots

01)

x = -2

square both sides

x² = 4

x² - 4 = 0

02)

x = 2

Square both sides

x² = 4

Multiply by 4 on each side

4x² = 16

Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".
