(5x-19)^2 < (x-23)^2
please someone help me with this inequality :c​

Answers

Answer 1

Answer:

[tex]x (-1,7)[/tex]

Step-by-step explanation:

We need to square a binomial.

The following rule is applied:

[tex](5x)^2+2*5x(-19)+(-19)^2<x^2+2x(-23)+(-23)^2[/tex]

In our example,

[tex]A^2+2AB+B^2=(A+B)^2[/tex]

   A is equal to 5x,

    B is equal to -19 and

   N is equal to 2.

[tex]5^2*x^2-2*5x*19+19^2<x^2x-23+23^2[/tex]

If the question is how many variable terms are in 3x^3y + 5x7 - 4y + x-z+9 the answer would be 7 because each of the variables are separated by the + and - signs and if you count them like that right now you would get 5 and if you add the 3 from the beginning you would get 7 saying that the variable terms are represented by the letters am I correct.

Answers

Given:

The expression is

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

To find:

The number of variable terms.

Solution:

Constant values, variables, product of constants and variables are known as terms if they are separated by  "+" sign.

The terms which contain atleast one variable is called variable terms.

We have,

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

Here, the terms are [tex]3x^3y,5x^7,-4y,x,-z[/tex] and 9.

All terms contain variables except 9 which is a constant.

Therefore, the number of variable terms is 5.

Hence, your answer was not correct.

Determine if the equations are parallel, perpendicular, or neither.
5x + 3y = 3 and 3x + 5y = -25

Answers

to easily find the slope from standard form (Ax + By = C) use -A/B

1. m = -5/3
2. m = -3/5

perpendicular slopes are negative reciprocals, which these are not

parallel slopes are exactly the same, which these are also not

so, these equations are neither parallel nor perpendicular

There are 1275 ants in 5 anthills how many are in 1 anthill?

Answers

Answer:

There are 255 ants in 1 anthill.

Step-by-step explanation:

Do the cross multiplication method. First set the equation as 1275/5 = x/1. Then cross multiply to get 5x = 1275. Divide both sides by 5 to get 255.

There are 225 ants in one ant hill

Answers

Answer:

1

Step-by-step explanation:

y-4=(x-2)

This equation is in point slope form

y-y1 = m(x-x1)

where m is the slope

The slope is 1

y - 4 = x - 2

y = x + 2

Slope-intercept form is y = mx + b, where m is the slope and b is a constant.

Here, m = 1 and b = 2. Therefore, the slope is 1.

Find the distance between points P(7.1) and Q(5,7) to the nearest tenth.
PQ =

Answers

Answer:

The answer is 6.3 units

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

P(7,,1) and Q(5,7)

We have

[tex] |PQ| = \sqrt{ ({7 - 5})^{2} + ({1 - 7})^{2} } \\ = \sqrt{ {2}^{2} + ({ - 6})^{2} } \\ = \sqrt{4 + 36 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{40} \: \: \\ = 2 \sqrt{10} \\ = 6.32455532...[/tex]

D. as a total number of family member increases the amount of money that the family spends on food increases

Answers

Answer: D. as a total number of family member increases the amount of money that the family spends on food increases

Step-by-step explanation:

Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'

i.e. independent variable acts like a cause to effect the dependent variable.

This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.

Hence, there is direct effect of number of people on food's cost.

Rest of options represents correlation but not causation .

Hence, the correction option is D.
