A.
function
B.
not a function

Answers

Answer 1
Answer: If the x value is repeated is is not a function. (unless it is a negative and a positive)
So lets see:
For A we have 3 6 9 12 no repeations so therefore It is A
For B we have 2 2 3 9, 2 is repeated so therefore it is B
For C we have 4 6 4 6, both 4 and 6 were repeated so therefore is is B
and lastly for D we have 3 5 6 6
And 6 was repeated so therefore it is B.
A)A
B)B
C)B
D)B

Answers

Start by adding 2y so that the equation becomes 2y= -3x-4 then divide by 2 on both sides so it cancelled out. (This if for if your trying to get it in y=mx+b form)

Cecilia bought a necklace made of silver and blue beads. The necklace had 30 silver beads and 36 blue beads. The information card on the necklace said that more than 1/3 of the beads are silver. Was the information on the card correct? Explain your answer.

Answers

The information was correct.

We can solve this by making a ratio of silver to the total number of beads.

30/66  Divide both sides by 6

5/11>4/12? 

Is 5/11 bigger than 1/3? Yep. It is. Therefore the information was correct.

The information on the card was correct because their are 66 total beads and 1/3 of that is 22 and there are 30 silver beads so the statement is True 

Complete the pattern 5,10,30,60,180, ?

Answers

Let

a1=5 \n a2=10\n a3=30\n a4=60\n a5=180

we know that

(a2)/(a1) = (10/5)=2 \n a2= a1*2

(a3)/(a2) = (30/10)=3 \n a3= a2*3

(a4)/(a3) = (60/30)=2 \n a4= a3*2

(a5)/(a4) = (180/60)=3 \n a5= a4*3

The pattern is times two then times three then times two then times three

so

the sixth term will be

a6=a5*2

a6=180*2=360

therefore

the answer is

360

540 is the answer because the doubled the first number to get the second number and multiplyed that by 3 to get the third number

3/5 of the visitors to the museum come during the week, and 4/10 come during the weekend. When does the museum get more visitors, during the week or during the weekend.

We know that 3/5 of the visitors to the museum come during the week, and that 4/10 come during the weekend. Since we want to know when the museum  gets more visitors, we need to compare 3/5 to 4/10.

Notice that 3/5 and 4/10 are unlike fractions so our first step is to find a common denominator. The common denominator of 5 and 10 is the least common multiple of 5 and 10 or 10.

To get a denominator of 10 for our first fraction 3/5, we must multiply both the numerator and denominator by 2 to get 6/10.

Notice that 4/10 already has 10 in the denominator so it stays the same. Now we have like fractions. To compare like fractions, we simply compare the numerators or the top numbers. Since 6 is greater than 4, we know that 6/10 must be greater than 4/10. Since 6/10 represents the number of visitors that come to the museum during the week, we know that the museum gets more visitors during the week.

Esther has 2/3 of blue dresses in her dresser. Dana has 6/9 of blue dresses in his dresser. Are the fractions equivalent?

Answer: Yes! The fractions are equivalent because when 6/9 is simplified, it would be 2/3.

1. Find three consecutive integers such that the sum of the first and twice the thirdinteger is 93 more than the second integer

Answers

Answer:

Step-by-step explanation:

Let (x), (x+1), and (x+2) be the three consecutive integers.

Put the words into expressions

Sum of the 3rd and twice the 3rd:  (x)+2(x+2)

93 more than the second integer: 93+(x+1)

Now you can set up the equation and solve:

(x)+2(x+2)=93+(x+1)

Distribute and combine like terms

x+2x+4=94+x

3x+4=94+x

2x=90

x=45

So the 3 consecutive integers are 45, 46, 47.

alrighty

so on anso forth

yes this is proportional.    what grade are you in? I want to teach u something to make it easy

since 5.7 is a constant, lets concider it equal to K & put it aside for a moment.
now, there is an (=) sign between x & y this means there is a proportionality relation between x & y. now if we reconcider the constant, it becomes y=Kx. it means tha y is equal to K times x i.e. if we write x K times, it'll be equal to y. now we know that if we remove constants form an equation, we can relate proportionality there.... so lets remove constants;
this implies y is proportional to x.
Hope it helps.
