Answer:

x^2 = 121

Step-by-step explanation:

Sea el ancho del terreno x metros

Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x

Matemáticamente, el área de un rectángulo es;

Anchura longitud Por lo tanto, tenemos

x * 2x = 242 metros cuadrados

Así; 2x ^ 2 = 242

x ^ 2 = 242/2

x ^ 2 = 121

Step-by-step explanation:

1. Covert decimal into fraction:

0.63 = 63/100

2. Simplify (1 is the greatest common divisor of 63 and 100. The result can't be further reduced):

63/100

Answer:I got -0.2

Step-by-step explanation:

The rate of change of y with respect to x for this function​ should be considered to be the -0.2.

Since

x = -3

y = 3.6

[tex]x_1[/tex] = 5

[tex]y_1[/tex] = 2

So here the rate of change be

[tex]= (y_1 - y) \div (x_1 - x)\\\\[/tex]

= (2-3.6) ÷ (5 + 3)

= -1.6 ÷ 8

= -0.2

Hence, The rate of change of y with respect to x for this function​ should be considered to be the -0.2.

Answer:

  m∠B < m∠A < m∠C

Step-by-step explanation:

We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.

For n = 4, the side lengths are ...

  a = 2(4) = 8

  b = (4) +3 = 7

  c = 3(4) -2 = 10

The longest side is opposite the largest angle, so the ordering of angles is ...

  m∠B < m∠A < m∠C

_____

The triangle inequality requires all of these inequalities be true:

That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

Answer:

Step-by-step explanation:

-3x + 4y = -20

y = x - 4

Put the second equation into the first equation in place of y.

-3x + 4 (x - 4) = -20

Multiply everything in the parenthesis by 4.

-3x + 4x - 16 = -20

Combine like terms.

x - 16 = -20

Add 16 to both sides.

x = -4

Put this into the second equation in place of x.

y = -4 - 4

y = -8

Your solution set is (-4,-8).

Answer:

for question 7 : I think it is no

Step-by-step explanation:

if you plot the points on a quick rough sketch you will find that none of the coordinates are on the same line (which they would have to be for a straight line). No points in those 3 coordinates are the same so the there cannot be two points on the same x or y coordiante therefore there is no right-angles triangle.

If you plot the points roughly there will not be two perpendicular lines so there is no right-angles triangle.

sorry I realise   this is confusing :(

Also for Question 5:

Parallel should be anything y= for example, y=6

Perpendicular should be anything x= for example x=6 as y=7 is a horizontal line and x=6 is a vertical line. Y=6 would be parallel because y=(any number with no gradient e.g. 1,2,3,4,etc.) is horizontal.

Answer:

A

You plug in the same x value for each and see the answer. So 2(5)*10^4= 100000. And for the other we do 4(5)*10^2 which is 200. Since is says that 2x10^4 is 50 times as great as 4x10^2, we know that a is right because 200 * 50 = 100000.

Question:

Sal is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month for unlimited usage. The second phone costs $150 and $51 per month for unlimited usage.

The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is .

The solution to the inequality is .

Sal’s mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.

Answer:

a. [tex]150 + 51x < 100 + 55x[/tex]

b. [tex]x > 12.5[/tex]

c. At least 13 months

Step-by-step explanation:

Given

First Phone;

[tex]Cost = \$100[/tex]

[tex]Additional = \$55[/tex] (monthly)

Second Phone;

[tex]Cost = \$150[/tex]

[tex]Additional = \$51[/tex] (monthly)

Solving (a): The inequality

Represent the number of months with x

The first phone is expressed as:

[tex]100 + 55x[/tex]

The second phone is expressed as:

[tex]150 + 51x[/tex]

For the second to be less expensive that the first, the inequality is:

[tex]150 + 51x < 100 + 55x[/tex]

Solving (b): Inequality Solution

[tex]150 + 51x < 100 + 55x[/tex]

Collect Like Terms

[tex]51x-55x<100 - 150[/tex]

[tex]-4x<-50[/tex]

Solve for x

[tex]x > -50/-4[/tex]

[tex]x > 12.5[/tex]

Solving (c): Interpret the solution in (b)

[tex]x > 12.5[/tex] implies 13, 14, 15....

Hence, She'll keep the second phone for a period of at least 13 months
