help how do i solve this​

Answers

Answer 1

Answer:

{x,y} = {7,-5}

Step-by-step explanation:

Solve equation [2] for the variable  y

  [2]    10y = -7x - 1

[2]    y = -7x/10 - 1/10

Plug this in for variable  y  in equation [1]

  [1]    5x + 9•(-7x/10-1/10) = -10

  [1]    -13x/10 = -91/10

  [1]    -13x = -91

Solve equation [1] for the variable  x

[1]    13x = 91

[1]    x = 7

By now we know this much :

x = 7

y = -7x/10-1/10

Use the  x  value to solve for  y

  y = -(7/10)(7)-1/10 = -5

Answer 2

Answer:

(x , y) = (7 , -5)

Step-by-step explanation:

{x, y} = {7, -5}

System of Linear Equations entered :  

1. 5x + 9y = -10

2. 7x + 10y = -1

(Shown on graph below)

Solve equation 3 for the variable the y    

10y = -7x - 1

y = -7x/10 - 1/10

Plug this in for variable  y  in equation 1    

5x + 9•(-7x/10-1/10) = -10

-13x/10 = -91/10

 -13x = -91


Solve equation 1 for the variable  x   
 13x = 91 

  x = 7 

By now we know this much :  

  x = 7

  y = -7x/10-1/10

Use the  x  value to solve for  y    

 y = -(7/10)(7)-1/10 = -5 

Hence, (x , y) = (7 , -5)

An aluminum bar 3 feet long weighs 12 pounds. What is the weight of a similar bar that is 3 feet 4 inches long?

Answers

Answer: 13 [tex]\frac{1}{3}[/tex] pounds

Step-by-step explanation:

     We will set up a proportion. I will have the weight, in pounds, on the top (numerator) and the length, in inches, on the bottom (denominator).

[tex]\frac{12}{36} =\frac{x}{40}[/tex]

     Cross-multiply:

36 * x = 12 * 40

36x = 480

     Divide both sides of the equation by 36:

x = 13 [tex]\frac{1}{3}[/tex] pounds

Answer:

Step-by-step explanation:

First find unit weight.

1 foot = 12 inches

3 ft = 3*12 = 36 inches

3ft 4 inches = 36 + 4 = 40inches

Weight of 36 inches  long bar =   12  pounds

Weight of 1 inch bar = 12/36

[tex]\text{Weight of 40 inches long bar = $\dfrac{12}{36}*40$}[/tex]

                                             = 13.3 pounds

Write an equation for the hyperbola that satisfies the given set of conditions.

Vertices (20,0) and (-20,0) conjugate axis of length 18 units.

Answers

The vertices of the hyperbola are the x-intercepts of the hyperbola

The equation of the hyperbola is [tex]\frac{y^2}{400} -\frac{x^2}{81} = 1[/tex]

How to determine the equation of the hyperbola?

The equation of a hyperbola is represented as:

[tex]\frac{(y - k)^2}{a^2} -\frac{(x - h)^2}{b^2} = 1[/tex]

The vertices are (20,0) and (-20,0).

So, the center of the hyperbola is:

(h,k) = (0,0).

Also, we have:

a = 20

This gives

[tex]\frac{(y - 0)^2}{a^2} -\frac{(x - 0)^2}{b^2} = 1[/tex]

Evaluate

[tex]\frac{y^2}{a^2} -\frac{x^2}{b^2} = 1[/tex]

Substitute 20 for a

[tex]\frac{y^2}{20^2} -\frac{x^2}{b^2} = 1[/tex]

[tex]\frac{y^2}{400} -\frac{x^2}{b^2} = 1[/tex]

The length of the conjugate axis is:

l = 18 units

So, we have:

[tex]b = \frac{18}2 = 9[/tex]

The equation becomes:

[tex]\frac{y^2}{400} -\frac{x^2}{9^2} = 1[/tex]

[tex]\frac{y^2}{400} -\frac{x^2}{81} = 1[/tex]

Hence, the equation of the hyperbola is [tex]\frac{y^2}{400} -\frac{x^2}{81} = 1[/tex]

How do you solve for n and what is the rule?

Answers

Answer:

Looking at the first two given ordered pairs (3, 5) and (4, 7), it appears that for every increase of 1 unit of x, there is an increase of 2 units of y.

Let's check by writing the next ordered pairs using this rule:

(5, 9)  (6, 11)  (7, 13)  (8, 15)

As the the ordered pair (8, 15) is in the table, then we can confirm that this is the rule.

Writing the rule as an equation:

y = 2x - 1

Therefore, n = 6

Answer:

y = 2x - 1

n = 6

Step-by-step explanation:

Hello!

This is an arithmetic sequence.

An Arithmetic sequence, also known as an arithmetic progression, is a string of numbers that follow a pattern where the difference between two terms is always the same (constant).

An Arithmetic sequence is modeled by the explicit function:[tex]\bold{t(n) = (CD)n + t(0)}[/tex]

t(n) = output (y - value)CD = common difference (slope)n = input ( x-value)t(0) = starting value (y-intercept)

Let's go step by step to solve these equations:

Step 1: Common Difference

The common difference of a sequence is similar to the slope of a line. The slope formula is given as [tex]\bold{\frac{y_2 - y_1}{x_2-x_1}}[/tex].

We can input values of x and y to find the common difference

[tex]\frac{y_2 - y_1}{x_2-x_1}[/tex][tex]\frac{7 - 5}{4 - 3}[/tex][tex]\frac21 = 2[/tex]

We have the CD, 2!

Step 2: Starting Value

The starting value can be shown as the y-intercept of the line or the origin point of the sequence.

To find the starting value or t(0), we can input an x and y value for "n" and "t(n)"

t(n) = (CD)n + t(0)5 = 2(3) + t(0)5 = 6 + t(0)-1 = t(0)

We know have the starting value, -1!

Step 3: The Equation

We now have all the values for our equation. let's bring our attention back to the input and output variables. Since we know that "t(n)" is the same as "y" and "n" is the same as "x", we can plug that instead of t(n) and n.

t(n) = (CD)n + t(0)t(n) = 2n -1y = 2x - 1

Solve for n:

With our equation, we can plug in 11 as the output and solve for n.

y = 2x - 111 = 2x - 112 = 2x6 = x

n = 6

_______________________________________________________

Another way to solve this is to find the Recursive Equation

The Recursive Equation is only meant to find the next term, it doesn't do so well in finding the terms in the long run.

The basic form of a recursive equation is t(n + 1) = t(n) + (CD); where t(0) is ____

I'm not going to go in-depth with this, but you can see the values that we solved above can be implemented here.

Our recursive equation is t(n + 1) = t(n) + 2; where t(0) is -1

The port outside of the semi-colon represents where the sequence starts. If only t(n+1) = t(n) + 2 is given, we could start at 5, and go as 5, 7, 9...etc.

We would start by finding t(1) by doing:

t(0 + 1) = t(0) + 2; where t(0) = -1t(1) = -1 + 2t(1) = 1

We can confirm this using our explicit rule: y = 2x - 1

y = 2(1) - 1y = 2 - 1y = 1

x + x + 500 = 5600

2x + 500 = 5600
