Find the domain in the following
Y=2x+5

Answers

Answer 1

Answer

All real numbers or (-∞, ∞)

Step-by-step explanation:

There aren't any X values that can make this linear equation output an invalid results, so we can deduce that the domain is all x values.

Answer 2

Answer:

All Real Numbers

Step-by-step explanation:

The Domain for a function simply is all the possible x values.

When graphing this function, you'll realize that it's continuous and passes all x values.

Additionally, when looking at it, you'll realize you can input any number of your choosing.

When trying to evaluate the domain of other functions, you can look at if any values of x will create an undefined value.

For example, some functions may have x in the denominator, and since the denominator can not be 0, there will be a discontinuity.

Other examples where the domain wouldn't be all real numbers would be if x was under a square root and couldn't be negative, or if the function was a vertical line.

Hope that helps, please let me know if you have any queries.

Maria started the year with $235 in the bank and is saving $15 a week. Sergio started with $685 and is spending $35 a week. When will they both have the same amount of money in the bank? Write an equation(s) to represent the situation and then solve. Be sure to define your variable(s) and clearly answer the question.

Answers

Answer:

9 weeks

Step-by-step explanation:

let the time when they will both have the same amount be x

since Maria is saving then her money is bound to increase

therefore amount she will have after x weeks=235+15x

Sergio is spending so his money is reducing

therefore amount he will have after x weeks=

685-35x

so

235+15x=685-35x

685-235=15x+35x

Answer:

x = 104°

Step-by-step explanation:

The 142° and <DCE form a straight line, and a straight line measures 180°, do the two angles add up to it:

180° =  142° + m<DCE

m<DCE = 38°

The red symbol in <DCE and <CDE mean they are congruent, so m<CDE is the same as m<DCE, which is 38°.

The 142° angle is an exterior angle to triangle, DCE, an exterior angles are the sum of the remote interior angles, which are <CDE and <DEC. Therefore, we can write:

142° = m<CDE + m<DEC

And we can substitute the values we have:

142° = 38° + x

x = 104°

Simplify: x+2/x+3 - x/x-1

Some loose change (pennies, nickels, dimes, and quarters) found behind the couch. Brianna noticed more than half the coins were pennies. Geofrey noticed that there was at least one coin of each type. Michele noticed that you could not make change for the same amount using fewer coins. In the space below, write the total amount of change, in cents, that was found.

Answers

The total amount of change, in cents, that was found is determined as 96 cents.

Total amount of change

The total amount of change is calculated as follows;

let the total = T

there was at least one coin of each type

T = p + n + d + q

more than half of the coins were pennies

[tex]\frac{p+n + d + q }{2} \leq p[/tex]

Value of the coinspennies = $0.01nickels = $0.05dimes = $0.1quarters = $0.25

more than half = pennies

next, we have; nickels + dimes + quarters

number of dimes

y(dimes) = $0.25

y(0.1) = 0.25

y = 0.25/0.1

y = 2.5 ≅ 3

dimes = 3 coins

number of nickels

since dimes = 3 coins, number of nickels is now calculated as;

x(0.05) = 3(0.1)

x = (0.3)/(0.05)

x = 6 coins

nickels = 6 coins

Total coins

Total coins = nickels + dimes + quarters + pennies

pennies must greater than 6 coins, since we can't have fewer coins.

Total coins = nickels + dimes + quarters + pennies

let pennies = 7

Total coins = 6 + 3 + 1 + 7

Total coins = 17

half of 17 = 8.5

7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.

let pennies = 11

Total coins = 6 + 3 + 1 + 11

Total coins = 21

half = 10.5

11 is more than half (10.5)

more than half = number of pennies = 11

Total amount in cents

11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

Find the slope of the graph of C

Answers

Step-by-step explanation:

the slope of a line or linear equation is always the factor of the driving variable.

usually in the form of

y = ax + b

x is the variable, and a the slope.

but in our case the variable is called "n".

it does not matter, the same principle applies.

the slope is the factor of n : 1050.

and as the slope is always the ratio y/x, we are looking for a fraction form, and that would be 1050/1.

so, the third answer is correct.

There are two numbers and one is 7 more than twice the other. the sum of the numbers is 43. What are the numbers

Answers

By solving a little system of equations we will see that the two numbers are 12 and 31.

How to find the numbers?

Let's define the two numbers as a and b.

We know that one of the numbers is 7 more than twice the other, so we have:

a = 2b + 7

We also know that the sum of the two numbers is 43, so we get:

a + b = 43

Replacing the first equation into the second one we get:

2b + 7 + b = 43

3b = 43 - 7 = 36

b = 36/3 = 12

Now that we know b, we can find a:

a = 2*12 + 7 = 31

So the numbers are 12 and 31.

Answer:

x = 20

y = √3 / 10

Step-by-step explanation:

The cosine ratio gives the ratio between the adjacent side and the hypotenuse.

The sine ratio gives the ratio between the opposite side and the hypotenuse.

Taking cosine ratio to find x :

cos 60° = 10/x

1/2 = 10/x

x = 20

Taking sine ratio to find y :

sin 60° = y/x

√3 / 2 = y/20

y = √3 / 10

Answer:

x= 20 ,  y= 10√3

Step-by-step explanation:

This question is clearly a trigonometry question

Please bare in mind :

Cos 60 = 1/2

Sin 60 = √3/2

Tan 60 = √3

Side x is the hypotenuse (h)

Side y is the Opposite (o)

And side with length of 10 is adjacent (a)

To find x, we have a, and we need h

So we use C = a/h

Cos 60 = 10/h

h = 10/Cos 60

h = 10/0.5

h = 20 ,  x=20

To find y, we can use pythagaros as we found the value of x :

10² + y² = x²

10² + y² = 20²

y² = 20²-10²

y² = 300

y = √300

y= √100×3   y=√100 × √3

y = 10√3

This is our y value

Another way to find y is trigonometry :

We have a and we need o so we use :

T = o/a

Tan 60  = o/10

o = 10×tan 60

o = 10×√3

o = 10√3 ,  y=10√3

The measure of an angle is 5°. What is the measure of its supplementary angle?

Answers

Answer:

175 degrees.

Step-by-step explanation:

Supplementary angles add up to 180 degrees

Therefore the answer is:

180 - 5

= 175 degrees.

Hi Student!

The first step to almost any problem is that we must concentrate the important information that is given to us in the problem.  This problem gives us information including that the measure of an angle is 5 degrees and that this angle is part of a supplementary pair.  Let's define what a supplementary pair or angles are.

Supplementary Angles:  These are two angles that are right next to each other on a straight line.  These angles combine to a total of 180 degrees.

Complementary Angles: These are two angles that are right next to each other but this time they are on a right angle.  These angles combine to a total of 90 degrees.

Now that we have our definitions and important information, we can move onto the next part which is actually finding the other angle.  This step is simple now that we know that supplementary angles add up to 180.  We can just create an equation that will help us determine our solution.

[tex]angle_1\ +\ angle_2 = 180\ degrees[/tex]

[tex]5\ degrees\ +\ angle_2 = 180\ degrees[/tex]

[tex]5\ degrees-5\ degrees\ +\ angle_2 = 180\ degrees-5\ degrees[/tex]

[tex]angle_2 = 175\ degrees[/tex]

Therefore, our final solution to the supplementary angle of 5 degrees is 175 degrees which can be found by subtracting the given angle from 180.
