What is Division?

A division is a process of splitting a specific amount into equal parts.

We have to choose yes or no to tell if the number 3 will make each equation true.

2÷□=3/2

To get 3/2 we have to divide two by three.

2/3=3/2

These are not equivalent so it is not yes.

The other expression 2 ÷ 6 = □

2 ÷ 6=1/3 which is not 3, so it is no.

The third expression

2 ÷ □ = 2/3

When we put 3 in the blank place we get two divided by three.

2 ÷ 3=2/3

Which is true so answer is yes for 3.

□ ÷ 8 = 3/8

When we put three in the blank we get three divided eight which is true.

3÷ 8 = 3/8 which is yes for 3.

Hence, 2 ÷ □ =2/3, □ ÷ 8 = 3/8 is true for x is true which choose is yes.

so basically, to graph the points, you look at the x axis first. look at the first point. for example,(-2,4) look at the x axis and find -2. then, go up four points. do that to the rest of the points, then connect the dots, labeling the corresponding points you to A,B, and C. based off of this graph, turning it clockwise means to mirror it from the y axis. 90 degrees mean clockwise! from the new graph, bring each point 3 units down. thats it! good luck!

50 POINTS QUICK Mary is three times as old as her son . In 12 years Mary will be twice as old as her son. How old is each of them now?

Answers

Answer: Mary is 36 and her son is 12; in 12 years her son will be 24 and she will be 48

Step-by-step explanation:

Answer:

Mary's age = 36

Son's age = 12

Step-by-step explanation:

Let x be age of Mary and y be age of her son.

According to question,

x = 3y...........(1)

And,

x + 12 = 2(y + 12)

x + 12 = 2y + 24

Replacing value of x from (1),

3y + 12 = 2y + 24

3y - 2y = 24 - 12

y = 12

And x = 3 x 12 = 36

f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

What is a function ?

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

here, we have,

We know, domain is:

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Thus , from the graph it can be clearly depicted that it is representing f(x)=-Lxl for an entire range of  -3 ≤x≤3 .

Hence , f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

Factor completely and then place the factors in the proper location on the grid. 25a 2 - 30a + 9

Answers

Answer:

(5a−3)^2

Step-by-step explanation:

25a^2 - 30a + 9

Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.

p+q=−30

pq=25×9=225

Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.

−1,−225

−3,−75

−5,−45

−9,−25

−15,−15

Calculate the sum for each pair.

−1−225=−226

−3−75=−78

−5−45=−50

−9−25=−34

−15−15=−30

The solution is the pair that gives sum −30.

p=−15

q=−15

Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).

(25a^2−15a)+(−15a+9)

Factor out 5a in the first and −3 in the second group.

5a(5a−3)−3(5a−3)

Factor out common term 5a−3 by using distributive property.

(5a−3)(5a−3)

Rewrite as a binomial square.

[tex]$\sqrt{5 x}\left(\sqrt{8 x^2}-2 \sqrt{x}\right) = \sqrt{5 x} \cdot \sqrt{8 x^2} - 2\sqrt{5 x} \cdot \sqrt{x}$[/tex]
