Answer:

0.00638

Step-by-step explanation:

Use some dimensional analysis. There are 60 minutes in 1 hour, and 60 seconds in 1 minute:

[tex] \frac{23}{1} \frac{units}{hour} \times \frac{1}{60} \frac{hour}{minutes} \times \frac{1}{60} \frac{minute}{seconds} [/tex]

The units of hour will cancel, minutes will cancel, leaving the units of seconds:

[tex] \frac{23}{60\times 60} \frac{units}{seconds} = 0.00638 \frac{units}{second} [/tex]

3(3x−5)

(3 times 3x)(3 times -5)

9x-15

Since you don't know what x is, you can't simplify it any more than this.

Hey there!

Use the Distributive Property to simplify the expression 3(3x - 5) :

9x - 15 ✅

- Distributive Property :

A(B - C) = AB - BC

- Given expression :

3(3x - 5)

>> Distribute the 3 to the 3x and to the 5 :

3(3x - 5)

= 3*3x - 3*5

Therefore, your answer is 9x - 15 .

Have a good day ;)

Answer: its gonna be 90k (90,000)

Step-by-step explanation: 4 hrs = 15k meaning if u add 4 + 4 its basically gonna be 15k + 15k. so in 24 hr its gonna be 90k because 4 + 4 + 4 +4 + 4 = 24 so if 4 is 15k then it would also be 15k + 15k + 15k +15k +15k and thats 90k.

The equation represents how much will be in the account after 2 years will be A = $6,500 + ($6,500 x 4 x 2)/100.

Let P be the principal, R be the rate of interest, and T be the time. Then the interest rate is given as,

I = (PRT)/100

6,500 dollars is placed in a savings account with an annual interest rate of 4%.

Then the amount after 2 years is calculated as,

A = P + I

A = P + PRT / 100

A = $6,500 + ($6,500 x 4 x 2)/100

Thus, the equation will be A = $6,500 + ($6,500 x 4 x 2)/100.

Hello! In this question, we will be changing our given equation to turn it into slope-intercept form.

__________________________________________________________

Explanation:

We are given the following equation:

3y − 3x = 15

Our goal is to turn the equation into slope-intercept form, which is:

y = mx + b

Let us rearrange the equation and simplify it:

3y − 3x = 15

Add 3x to both sides, which would cancel the 3x on the left.

3y = 3x + 15

Now, divide everything by 3 to get the "y" variable by itself.

y = x + 5

Therefore, your simplified equation in slope-intercept form would be:

y = x + 5

__________________________________________________________

Answer:

y = x + 5

__________________________________________________________

Part I: Reviewing the slope intercept form equation

Given equation:

Slope intercept form: y = mx + b

[Where "m" is the slope and "b" is the y-intercept]

Part II: Isolating "y" and it's cooeficient on one side of the equation

In the slope intercept form equation, we can see that the "y" variable is completely isolated on one side of the equation. Therefore,

Part III: Isolating "y" from it's cooeficient

The "y" variable in the slope intercept form has no cooeficient. Therefore, we need to isolate the cooeficient of "y" in our equation ( 3y = 3x + 15 ). This can be done by dividing 3 both sides or multiplying 1/3 both sides.

Part IV: Simplify the other side of the equation

Finally, simplify the other side to obtain our equation in slope intercept form.

Therefore, the equation in slope intercept form is y = x + 5.

The equation of the line that is parallel to the line y = 4x + 13 and passing through the point (4, 32) will be y = 4x + 16. Then the correct option is D.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The equation of the line is given below.

y − 1 = 4(x + 3)

The equation can be written as

y = 4x + 13

Then the equation of the line that is parallel to the line  y = 4x + 13 and passing through the point (4, 32) will be

The slope of the parallel lines will be the same

Slope = 4

Then

y = 4x + c

The line is passing through (4, 32)

32 = 4(4) + c

32 = 16 + c

 c = 16

The equation of a parallel line is y = 4x + 16

The relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.

A trinomial is the type of algebraic expression in which there are three terms present and more than one variable are present.

The trinomial given in the problem is,

[tex]x^2 +bx - c[/tex]

This trinomial has factors of,

[tex](x +m)(x - n),[/tex]

Where m, n, and b are positive.

If this factors multiply by each other, we get,

[tex](x +m)(x - n)\\x^2+nx+mx+nm\\x^2+(n+m)x+nm[/tex]

Compare it with the trinomial, we get,

[tex]b=(m+n)[/tex]

Which is the sum of the terms,

[tex]c=nm[/tex]

Which is the product of the terms.

Hence, the relationship between the values of m and n for the trinomial x²+bx -c is (m+n) is the sum of the roots and (mn) is the product of the roots.

Step-by-step explanation:

A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

A centimeter is a unit to measure a length in the metric system. One centimeter is equal to 0.39 inches.

It is given that

3.25 cm length of rope weighs 61.40 grams.

There are 28.3495 grams in an ounce.

There are 2.54 centimeters in an inch.

a = b

c = x

So x = cb / a

If there are 2.54 centimeters in 1 inch,

centimeters= 19.45 × 2.54/ 1 inch

centimeters= 49.403

Now, if 3.25 centimeters long weighs 61.40 grams, then

grams= 49.403 × 61.40 / 3.25 centimeters

grams= 933.34

Finally, if there are 28.3495 grams in 1 ounce,

ounces= 933.34 × 1 ounce / 28.3495 grams

ounces= 32.92

Thus, A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

Step-by-step explanation:

First of all we need to find the equations of the lines :

y( red ) = - x + 2

y(blue) = 2x - 1

Then we must to put the equations equal to each other and going to to find the value of x :

[tex]- x + 2 = 2x - 1[/tex]

Add both sides x

[tex] - x + x + 2 = 2x + x - 1[/tex]

[tex]2 = 3x - 1[/tex]

Add both sides 1

[tex]2 + 1 = 3x - 1 + 1[/tex]

[tex] 3 = 3x[/tex]

Switch sides

[tex]3x = 3[/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{3}{3} \\ [/tex]

[tex]x = 1[/tex]

After u the value of x , put it in one the equations to find the value of y :

[tex]y = - x + 2[/tex]

[tex]y = - (1) + 2[/tex]

[tex]y = - 1 + 2[/tex]

Answer:

267

Step-by-step explanation:

We are given the expression:  6 (d - f) +f

The value of the expression when d= 47 and f = 3 is :

6 (47 - 3) +3 = 6×(44) + 3 = 264 + 3 = 267

=267

The y-value of the solution to the system of equations is 2.

We have given a system of equation

3x + 5y = 1

7x + 4y = −13

A system of equations is a collection of two or more equations with the same set of unknowns.

First we have to find the value of x.

3x + 5y - 5y = 1 - 5y

divide both sides of the equation by 3

3x/3 = 1/3 - 5y/3

x = 1/3 - 5/3y

Now plug that into the other equation,

7(1/3 - 5/3y) + 4y = -13

7/3 - 35/3y + 4y = -13

7/3 - 7 2/3y - 7/3 = -13 - 7/3

- 7 2/3y (-3/23) = -15 1/3 (-3/23)

y = 2

The answer is 2.
