Inequality has a set of solutions there could be infinitely many solutions to inequality.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Let's consider inequality,

n > 3 where n is the natural number.

Now 4,5,6,7.... up infinite will be the solution of the inequality.

Therefore, inequality consists of infinitely many solutions.

Hence "Inequality has a set of solutions there could be infinitely many solutions to inequality".

Answer:

x = [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1-x}{1+x}[/tex] = [tex]\frac{2x+1}{-2x+5}[/tex] ( cross- multiply )

(2x + 1)(1 + x) = (1 - x)(- 2x + 5) ← expand parenthesis on both sides using FOIL

2x + 2x² + 1 + x = - 2x + 5 + 2x² - 5x , simplify

2x² + 3x + 1 = 2x² - 7x + 5 ( subtract 2x² from both sides )

3x + 1 = - 7x + 5 ( add 7x to both sides )

10x + 1 = 5 ( subtract 1 from both sides )

10x = 4 ( divide both sides by 10 )

x = [tex]\frac{4}{10}[/tex] = [tex]\frac{2}{5}[/tex]

Answer:

 x = 2/5

Step-by-step explanation:

[tex]\frac{1-x}{1+x}=\frac{2x+1}{-2x+5}[/tex]

Cross multiply,

(1 - x)(-2x + 5) = (2x +1)(1 + x)

Use FOIL method to multiply,

1*(-2x) + 1*5  - 2x *(-x) + 5*(-x) =2x *1  + 2x *x  + 1*1 + 1*x

             -2x + 5  + 2x² -5x    = 2x + 2x² + 1 + x

Combine like terms,

              -2x - 5x + 2x² + 5 = 2x² + 2x +x  + 1

                      -7x + 2x² + 5 = 2x² + 3x + 1

           -7x + 2x²  - 2x² - 3x  = 1 -  5

                             -7x - 3x    = - 4

                                       -10x = -4

                                          x = -4/-10

                                          x = 2/5

Answer:

60/100 times by 95 so 57

Step-by-step explanation:

Answer:

Step-by-step explanation:

When parabola f(x) = ax² + bx + c passes through point (x₁, y₁) that means if x=x₁ then f(x)=f(x₁)=y₁

(0, 6) ⇒   6=a·0²+b·0+c    ⇒   c=6

f(x) = ax² + bx + 6

(-3, 15)  ⇒  15 = a(-3)² + b(-3) +6   ⇒  9a - 3b = 9 ⇒

                                                      ⇒ 3a - b = 3  ⇒ b = 3a - 3

(-6, 6)  ⇒  6 = a(-6)² + b(-6) +6  ⇒ 36a - 6b = 0  ⇒

                                                      ⇒  6a - b = 0   ⇒ b = 6a

6a = 3a - 3   ⇒  3a = - 3  ⇒  a = -1

b = 6(-1) = -6

So the equation:

                         f(x) = (-1)x² + (-6)x + 6

                         f(x) = -x² - 6x + 6

Answer:

D. 2(6x + 5 + 2y)

Step-by-step explanation:

You have to use the distributive property to get your answer. 2 × 6x = 12x; 2 × 5 = 10; 2 × 2y = 4y.

the reflected image of the point (5,-1) under the y-axis is (-5, -1).

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given a coordinate (5, -1), find the image of the coordinate under a reflection in the y-axis.

Since

thus, Coordinates of image = (-5, -1)

Therefore, the image of the point (5,-1) under a reflection in the y-axis is (-5, -1).

Answer:

-3<x<5

Step-by-step explanation:

Given the inequality 2x-3<7 and 5-x<8

Solve 2x-3<7

Add 3 to both sides

2x-3+3 < 7+3

2x < 10

2x/2 < 10/2

x < 5

Solve 5-x<8

subtract 5 from both sides:

5-x-5<8-5

-x < 3

multiply both sides  by -1

-(-x) > -3

x > -3

-3<x

Combine both solutions x < 5 and -3<x

-3<x<5

The solution to the compound inequality is -3<x<5

Given:

Jan and Julie started their ride at 09:30 and finished at 15:15.

Stopped for a drink = 20 minutes

Lunch = 45 minute

Rest = 10 minutes

To find:

Time they are riding on their bikes (excluding stops).

Solution:

Jan and Julie started their ride at 09:30 and finished at 15:15.

So, total time of ride including stops is 5 hours 45 minutes or we can say 345 minutes calculated as

[tex]30+60+60+60+60+60+15=345\text{ minutes}[/tex]

We need subtract Drink, lunch and rest time from the total time to get the Time they are riding on their bikes (excluding stops) is

[tex]345-20-45-10=270 \text{ minutes}[/tex]

Therefore, the total time they are riding on their bikes (excluding stops) is 270 minutes.

Answer:

Area = 156.25π meters

Step-by-step explanation:

In order to identify the area of the circle, you would need the radius. In order to find the radius, you would plug in the circumference (25π) into the equation for the circumference of a circle, like this:

C = 2πr

25π = 2πr

You would then solve the equation for r  (the radius)

25π = 2πr

12.5π = πr

12.5 = r  

Then you would plug the radius into the equation for the area of a circle.

A = π(r^2)

A = 12.5^2π

A = 156.25π

So your answer would then be 156.25π meters, since that was the unit of measurement

Answer: 156.25π m. Hope this helps.
