1-x/1+x=2x+1/-2x+5 find x
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

Find the measure of the exterior angle
Answer:
Im not sure but go with 24
exterior angle = sum of its opposite interior angles
Which means :-

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

Find the equation in standard form of the
parabola that passes through the points (0, 6),
(-3, 15), and (-6, 6).
Answer:
f(x) = -x² - 6x + 6Step-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

Rita baked pies at the corner bakery the number Of pies she can bake x is limited by the ingredients they have in stock situation is represented by the compound inequality 2c-3<7 and 5-x<8 Solve the compound any quality inn select all the value solutions
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
Jan and Julie went for a bike ride. They started their ride at 09:30 and finished at 15:15. • They stopped for a drink for 20 minutes • They took 45 minute for lunch • They rested for 10 minutes. How long were they riding on their bikes for? (excluding stops)
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.

The circumference of a circle is 25π m. What is the area, in square meters? Express your answer in terms of \piπ.
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.

the image if the point (5,-1) under a reflection in the y-axis is
the reflected image of the point (5,-1) under the y-axis is (-5, -1).
What are coordinates?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
When a point is reflected in the x-axis, the sign of its ordinate changes. When a point is reflected in the y-axis, the sign of its abscissa changes. When a point is reflected in the origin, the sign of its ordinate and abscissa both change.thus, Coordinates of image = (-5, -1)
Therefore, the image of the point (5,-1) under a reflection in the y-axis is (-5, -1).
