The value of yvaries directly with x. If x= 3, then y= 21.
What is the value of x when y= 105?

Answer:

(x,y)=(2,5)

Step-by-step explanation:

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).

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:

-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

Answer:

45.23

Step-by-step explanation:

Answer:

25.66+13.20+6.36=45.22

Step-by-step explanation:

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:

Step-by-step explanation:

A fucntion is basically a machine that follows the instructions it's given and based on those instructions it gives you an answer. So in the function

f(x)=-x+7, our total output (answer) is going to be whatever our "x" is and adding that to 7.

So lets start with -2, plug in -2 for the x variable

f(x)=-(-2)+7, when we solve this we get f(x)=2+7 (negative*negative=positive)

so our final function would be f(x)=9

We can solve the other functions by plugging in the x variable in the same way:  

f(x)=-(-1)+7  this simplifies to f(x)=1+7, so f(x) equals 8

f(x)=-(0)+7   this simplifies to f(x)=0+7, so f(x)=7

f(x)=-(1)+7  this simplifies to f(x)=-1+7, so f(x)=6

f(x)=-(2)+7 this simplifies to f(x)=-2+7, so f(x)=5

Answer:

[tex]m=-54[/tex]

Step-by-step explanation:

We have the equation [tex]3-\frac{m}{6}=12[/tex] and we want to solve for m using the Properties of Equality.

Steps:

1) Subtraction Property of Equality (subtract 3 from both sides):

[tex](3-\frac{m}{6})-3=(12)-3[/tex]

[tex]-\frac{m}{6}=9[/tex]

2) Multiplication Property of Equality (multiply both sides by -6):

[tex]-6(\frac{m}{-6})=-6(9)[/tex]

[tex]m=-54[/tex]

Therefore, our final answer is [tex]m=-54[/tex]

Answer:

The answer is x = - 3

Step-by-step explanation:

You multiply both sides of the equation by  4 x^3 = -27

Write or type it in exponential form with an exponent of  3 x^3 +( -3)^3

Take the root of both sides of the equation  x^3= (-3) ^3

Solution is: x = - 3

Answer: $1,260

Explanation: Because Jordan is depositing $25 every week, for 36 weeks, we'd need to multiply 25 x 36. The product would be $900. But since Jordan had $360, we need to add 900 + 360 to get the final sum. Therefore, Jorndan would have $1,260 after 36 weeks.

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

Im not sure but go with 24

exterior angle = sum of its opposite interior angles

Which means :-

[tex]21 + 63 = 2x[/tex]

[tex]84 = 2x[/tex]

[tex]2x = 84[/tex]

[tex]x = 84 \div 2[/tex]

[tex]x = 42°[/tex]
