Determine whether the lines are parallel, perpendicular, or neither. 5x + 2y = 14 and y = −5x + 9

58 i think

58*2+64=180

Answer:

Width = 9

Step-by-step explanation:

(P=2L+2W) = 72

L = 3W<- length is triple the width

(P = 2(3W) + 2W) = 72

P = 8W =72

W = 9

Answer:

g

Step-by-step explanation:

8/100 is the same as 0.08 and 8,0% doesn't change and 2/25 is 8% as 1/25 is 4 so 2 would be 8 and it is g as 4/5 is 80%

Answer:

y = -3x +7

Step-by-step explanation:

The equation for a line is: y = mx + b

m = slope

x = the x-value

y = the y-value

b = the y-intercept

Since the y-intercept is 7, we know the first part of the equation is: y = mx +7

Also, since the line is decreasing from right to left, m is going to be negative. A way to calculate the m is rise/run. Count how many blocks it is going horizontally (run)and how many blocks it is increasing/decreasing when going to the right (rise). Then divided the "rise" over "run". Another way is to choose two points. Now use the equation y1-y2/x1-x2,

or  y2-y1/x2-x1. I am going to show using the equation.

My two points are (0,7) and (2,1)

change in y (rise):7-1 = 6

change in x (run): 0-2 = -2

6/-2 = -3. Your slope is -3. Now lets put it all together.

y = -3x +7

You can see that for every square moved to the right ONCE the y value is decreasing by 3 each time.

Answer:

one solution

Step-by-step explanation:

Given the equations

1/4x + 1 1/2y =5/8 ..... 1

3/4x - 1 1/2y =3 3/8 ..... 2

Get the value of x

Add both equations

1/4x + 3/4x = 5/8+3 3/8

4x/4 = 5/8+27/8

x = 32/8

x= 4

Substitute x = 4 into equation 1

From 1;

1/4x + 1 1/2y =5/8 .

1/4(4) + 3/2 y = 5/8

1 + 3/2 y = 5/8

3/2 y = 5/8 - 1

3/2 y = -3/8

Cross multiply

24y = -6

y = -6/24

y = -1/4

Hence the solution {x,y) is (4, -1/4)

The system has only one solution

Answer:

9a)   6 miles

9b)  12:20

Step-by-step explanation:

for first question, use the distance formula:  distance = rate · time

d = 2 x 3

d = 6 miles

for second question, she began walking home at 11:05 and it took 1 hour, 15 minutes (15 minutes is 1/4 of 60 minutes)

11:05 + 1 hour = 12:05

12:05 + 15 minutes = 12:20

Answer:

x + y = 2

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y + 3 = - (x - 5) ← distribute

y + 3 = - x + 5 ( subtract 3 from both sides )

y = - x + 2 ( add x to both sides )

x + y = 2 ← in standard form

Answer:

Yes, store's profit is proportional to number of customers

Step-by-step explanation:

Yes, the profit is proportional to the number of customers.

Profit = Revenue - Cost = (Price x Quantity) -  Cost

Profit = (0 x 20) + (3 x q) - c(20+q) : Where q refers to quantity beyond 20, & c is average cost per unit

Profit = 3q - 20c - cq = (3 - c)q + 20c

As 20c is constant, component of equation has coefficient 'q' which stands for quantity of sales ie number of customers

Given:

[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]

To find:

The value of given expression.

Solution:

We have,

[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]

It can be written as

[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{4\times 3}[/tex]

[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+2\sqrt{3}[/tex]

Using distributive property, we get

[tex]=4\sqrt{7}-2(2\sqrt{7})-2(\sqrt{3})+2\sqrt{3}[/tex]

[tex]=4\sqrt{7}-4\sqrt{7}-2\sqrt{3}+2\sqrt{3}[/tex]

[tex]=0[/tex]

Therefore, the value of given expression is 0.

Answer:

  (d)  Reflexive Property of ≅; SSS

Step-by-step explanation:

There are no angles involved in the proof, so the SAS claims do not apply.

__

The symmetric property says ...

  if A ≅ B, then B ≅ A

The reflexive property says ...

  A ≅ A

In this case, the reflexive property is the one being invoked in the statement ...

  AC ≅ AC

That, together with the claims of line 3 concludes the claim that all three sides are congruent to their corresponding counterparts. Hence the SSS postulate applies.

Answer:

The value of x is 16

Step-by-step explanation:

Given two angles are:

(4x + 19) and (7x -29)°

Two angles being congruent means that their numerical values will be equal

Putting both expressions equal

[tex]4x+19 = 7x-29[/tex]

Subtracting 7x from both sides

[tex]4x+19-7x = 7x-29-7x\\-3x+19 = -29[/tex]

subtracting 19 from both sides

[tex]-3x+19-19 = -29-19\\-3x = -48[/tex]

Dividing both sides by -3

[tex]\frac{-3x}{-3} = \frac{-48}{-3}\\x = 16[/tex]

Hence,

The value of x is 16

Answer:

C. 50ft

Step-by-step explanation:

Perimeter is the outside and in perimeter you add

The length is 15ft

The width is 10ft

There are 4 sides so you want to add the length and width 2 times

L = 15 + 15 = 30

W = 10 + 10 = 20

Then add it all together

30 + 20 = 50

Answer:

B: (2, -1)

Step-by-step explanation:

Answer:

The y-value sequence on 1  linear. The x-value sequence on 1 is also linear.

The y- value sequence on 2 is linear. The x-value sequence on 2 is also linear.

The y-value sequence on 3 is linear. However I now think you are referring to the domain and range also linear graphs and non linear graphs, maybe I've confused you.

Step-by-step explanation:

So the difference between an exponential function and a linear function is whether it is arithmetic sequence or geometric sequence or just another sequence.

arithmetic is if the numbers are added by the common difference.

geometric is if the numbers are multiplied by the common ratio.
