what is the product of (2/5x-3/4y^2) and (2/5x+3/4y^2)?

Answer:

x=3

Step-by-step explanation:

0 = x -3

-x = -3

change the sign to positive so x= 3

Answer:

x = 8

Step-by-step explanation:

[tex]xp = 2 + \frac{3}{5} (12 - 2) [/tex]

I did 12 -2 which equals 10

10 times 3/5 equals 6

6 plus 2 equals 8

Answer:

-7x

Step-by-step explanation:

2x + 3x - 12x

Add 2x + 3x, resulting in 5x

5x - 12x = -7x

It's negative because the -12 is the bigger number.

Hope this helps :D

Answer:

y=x+1

Step-by-step explanation:

The first step I took was to find the slope. A slope is equal to the rise over the run. The equation goes up 2 for every 2 it goes over, which means that the slope is 2/2 or 1. Then you need to determine the y intercept. I usually go about this by thinking logically about the problem. Because there is a point at (4,5) and the slope is 1, there must also be a point at (3,4) (2,3) (1,2) and (0,1) Because the x value in (0,1) is 0, we know that the y intercept must be 1, so I added 1 to the equation. The last step is putting it all together. We know that a linear equation is y=mx+b (m being the slope, b being the y-intercept) so the final equation is y=x+1

Answer:

5:8 po ba ang ratio kasi 5mike

and 8randy old

The proportional relationships that have the same ratio to that of mike and randys age include:

Since Mike is 5 years old and Randy is 8 years old, their ratio is 5:8.

Also, since Sarah is 40 years old and her mother is 64 years old. We can divide their ages by 8. Then the ratio will be 5:8.

Phill is 40 years old and Moleka is 25 years old. We can divide their ages by 5. Then the ratio will be 5:8.

Answer:

p - 3

Step-by-step explanation:

"fewer than" means subtract from, in this case 3, from an unknown number represented by p

The expression represents the phrase: “3 fewer than a number, p" is

(p-3).

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

We have,

Statement - “3 fewer than a number, p”

We know that the symbol for fewer would subtraction.

Then, the mathematical expression for 3 fewer than a number, p is

= (p - 3)

Step-by-step explanation:

The formula of a slope

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put the coorcinates of the points:

(2, 3); (5, 5)

[tex]m=\dfrac{5-3}{5-2}=\dfrac{2}{3}[/tex]

(2, 3); (8, 7)

[tex]m=\dfrac{7-3}{8-2}=\dfrac{4}{6}=\dfrac{4:2}{6:2}=\dfrac{2}{3}[/tex]

The point (2, 3), (5, 5) and (8, 7) are collinear because have the same slope.

Complete  Question

An online poll has a question that appears on the screen, and you simply click buttons to vote "Yes, " "No, " "Not sure, " or "Don't care." On a particular day, the results of a question were tallied. In all, 636 said "Yes, " another 595 said "No, " and the remaining 93 indicated that they were not sure.

a)

What is the sample size for this poll?

b)

Compute the percent of responses in each of the possible response categories. (Round your answers to two decimal places.)

c)

Discuss the poll in terms of the population and sample framework that we have studied in this chapter.

i)

This random sample of responses collects the opinions of a random group of users across all users of the Internet.

ii)

This voluntary response sample collects only the opinions of those that visit this site every day.

iii)

This random sample of responses collects the opinions of a random group of users of the particular site.

iv)

This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.

Answer:

a

   [tex]n  =  1324[/tex]

b

  YES             [tex]y  = 48.03 \% [/tex]

    NO             [tex]m  =44.94 \% [/tex]

   NOT SURE  [tex]m  =7.02\% [/tex]

c

The correct option is (iv)

Step-by-step explanation:

From the question we are told that

The voting options are "Yes, " "No, " "Not sure, " or "Don't care."

The number of people that said is [tex]Y = 636[/tex]

The number of people that said No is [tex]N = 595 [/tex]

The number that indicated Not sure is [tex]S = 93[/tex]

Generally the sample size is mathematically represented as

[tex]n = Y + N + S[/tex]

=> [tex]n = 636 + 595 + 93[/tex]

=> [tex]n = 1324[/tex]

Generally the percentage of responses that was Yes is mathematically represented as

[tex]y = \frac{636}{ 1324} * 100[/tex]

=>     [tex]y  = 48.03 \% [/tex]

Generally the percentage of responses that was No is mathematically represented as

[tex]m = \frac{595}{ 1324} * 100[/tex]

[tex]m =44.94 \% [/tex]

Generally the percentage of responses that was Not sure is mathematically represented as

[tex]s = \frac{93}{ 1324} * 100[/tex]

[tex]m =7.02\% [/tex]

The answer is B. 350 euros

Step-by-step explanation:

350 euros was the initial value of Luna's savings. Thus option B is correct.

Merging objects and identifying them since one big bunch is done through addition. In arithmetic, addition is the technique of adding two or more integers together. The product can meet are the quantities that are included, and the outcome of the operation, or the final response, is referred to as the sum.

The data that is presented suggests that there will not be a change in the first week this remains still at 315. They left out the amount that was 35.

Therefore the initial amount of the savings that the person has was the sum of both amounts.

= 315 + 35

= $350

Therefore, option B is the correct option.
