Every second, the water level increases by 10 mm and this value also represents the slope

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The graph represents the given parameter

From the graph, we have the following points

(x, y) = (0, 0) and (1, 10)

The increase in height each second is then calculated as

Increase = (y2 - y1)/(x2 - x1)

This gives

Increase = (10 - 1)/(1 - 0)

Evaluate

Increase = 10

Hence. the increase in height each second is 10 mm

In (a), we have

The increase in height each second is 10 mm

The increase in height each second is also the slope of the graph

Hence, the slope of the graph is 10 mm

The solution to the system is where the lines intersect. If they intersect once, then there is one solution. If the lines intersect twice, there are two solutions. You probably get the picture. So yes, your answer should be correct.

Hope this helps! :)

Answer:

yes it is

Step-by-step explanation:

yeah it is correct

The equation with solution zero are : b. 2 (x + 6) = 3 (x + 4) and  d. 3x + 8 = 2x+8.

Here in this problem, we are dealing with linear equations which is a condition of one variable regularly composed within the form ax+b=0 where a and b are real numbers and x is an unknown variable. Solutions to linear equations is refer to a linear equation that can have zero, one, or infinitely numerous solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution simplifies to a solution of the form x=n where n may be a real number. A linear equation with infinitely numerous solutions simplifies to a true statement without a variable such as 1=1.

So in the above-given equations

a. 4x + 1 = 4x - 1 => 4x-4x =1-1 =>0=0

b. 2 (x + 6) = 3 (x + 4)

=> 2x+12=3x+12

=>3x-2x= 12-12

=>x=0

c. 2x + 5 = 11

=>2x= 11-5

=>x=3

d. 3x + 8 = 2x + 8

=>3x-2x =8-8

=>x=0

The measure of the angle TRS = 46°

The angles given in figure are :

angle QSR = 110°

angle STR = 64°

angle QRS = 2x-10°

We will find the angle TRS using these given angles and some angle properties in a triangle.

We have the fact that sum of three angles of a triangle = 180°

So angle TRS + angle RST + angle STR = 180°

angle QSR and angle RST are supplementary. i.e., their sum = 180°

So angle RST = 180° - 110° = 70°

So angle TRS = 180°- (70°+64°) = 46°

Using angle TRS we can also find angle QRS and thereby, the value of x.

From the figure, angle QRT = 90°.

So angle QRS = 90°-angle TRS

⇒ 2x - 10° = 90° - 46°

⇒ 2x = 44° + 10°

⇒ x = 54°/2

⇒ x = 27°

The graph represents the given parameter

From the graph, we can see that the graph represents a linear function

Note that:

linear functions are functions that have constant average rates of change.

Having mentioned that, we have the following computations:

When x = 6 on the graph, g(x) = 0

This means that g(6) = 0

When x = 2 on the graph, g(x) = 2

This means that g(2) = 2

When x = 0 on the graph, g(x) = 3

This means that g(0) = 3

When g(x) = -1 on the graph, x = 8

This means that g(8) = -1

When g(x) = 1 on the graph, x = 4

This means that g(4) = 1

The value of given expression is [tex]10^7[/tex] which can be said as 10 raised to the power 7.

We have to find the value of [tex]10^5*\frac{10^4}{10^2}[/tex]

It is a question of exponents and powers.

Exponents (Power)

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself. It is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.

For example, the mass of Earth is 5,97,219,00,00,00,00,00,00,00,00,000 kg. This cannot be read in simple words. Thus, to pronounce these types of numbers we make use of exponents.

Hence, the weight of earth will be written as [tex]5.97219 * 10^{24}[/tex].

We know that:-

[tex]x^a*x^b = x^{a+b}[/tex] and,

[tex]x^a/x^b = x^{a-b}[/tex]

Hence, we can write,

[tex]\frac{10^4}{10^2} = 10^{4-2} = 10^2[/tex]

Step-by-step explanation:

Answer: (5,10)

Step-by-step explanation: We are given that a factory's production is modeled by function  f(x).

Where f(x)=Number of parts produced per hour

x=Number of people working during production

We have to choose an ordered pair that represents a possible domain and range of the function.

x is the number of people working during production. It is always positive because time can not be negative.

f(x) is the number of parts produced per hour .It is always positive because quantity of any number cannot be negative. It is always positive.

In first option (-1,15)

x=-1,f(x)=15

x is negative which is not possible.

So, it is false.

In option b(5,-50)

x=5,f(x)=-50

Range is negative which is not possible.

So , it is false.

In option C( -10,-100)

x=-10, f(x)=-100

x and f(x) are both negative  therefore, it is false.

In option D (5,10)

x=5 , f(x)=10

x and f(x) are both positive.

So, it is possible ordered pair.

Hence, ordered pair (5,10) in which 5  represent  a possible domain and 10 represent the possible range.

Step-by-step explanation:

An equation for a line that passes through (0, 0) and is parallel to a line that passes through (-5, 3) and (2, 1) is 0 = (-2/7)0 + 0

Two or more lines that never intersect are said to be parallel. We can see parallel lines all around us, such as in the bookcase's shelves and the two sides of this page.

There is a good chance that lines or structures that appear to run in the same direction, never cross one another, and always have the same spacing between them are parallel.

We will find the slope using the slope formula that is

⇒ m  = (y₂ - y₁)/(x₂ - x₁)

Given points are (-5, 3) and (2, 1), so

⇒ m  = (1 - 3)/(2 - (-5))        

⇒ m  = -2/7

We have asked to write an equation for a parallel line that passes through (-5, 3) and (2, 1).​

for a two lines to be parallel, m = m for both lines

so as the slope is (-2/7), lets put the value in (0,0)

y = mx + b

0 = (-2/7)0 + b

b = 0

And therefore the equation is 0 = (-2/7)0 + 0

Step-by-step explanation:

He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is:  $10000 + $1500 = $11500

a) the derive equation is 50000 + 10000 + x

jack has maximum amount of wealth = $50,000

When he participated in a jujitsu competition  then the prize amount = 10,000

Then we will take a variable x for derive the equation which will depend on that he will win and loose :

Here,

the equation is = 50000 + 10000 + x

b) His consumption after not purchasing medical insurance is $15000.

if, he does not purchase medical insurance  then he has no coverage of insurance and

He’ll lose the tournament and he’ll have to pay medical expenses dollar 5000 and also the prize amount $10000

So, his consumption after not purchasing medical insurance is:

$10000 + $5000 = $15000

c) when he will purchase medical insurance then his total consumption is $3500

his consumption if he purchase medical insurance, he will give dollar1 for medical insurance and will get in return dollar .3 ,

When he will have to pay for medical insurance $5000, then he’ll get the coverage on medical insurance:

0.3 * 5000 = $1500

Now, subtracting the amount of medical insurance which he’ll have to pay:

$5000 - $1500 = $3500

He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is:

 $10000 + $1500 = $11500

The domain and range of the function f ( x ) is {x all real numbers}; {yl y >0}

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.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2( ∛108 )²ˣ

The domain of the function is all real numbers because there are no restrictions on the variable x.

To find the range, we can simplify the function as follows:

f(x) = 2(∛108)²ˣ

f(x) = 2(6)²ˣ

f(x) = 2(36)ˣ

f(x) = 72ˣ

Since 72ˣ is always positive, the range of the function is {y: y > 0}.

Hence , the domain and range is solved and = {x ∈ R : x ∈ R }, {y ∈ R: y > 0}
