=

x=4 and y=1

Answer:

x=4

y=1

Step-by-step explanation:

Step-by-step explanation:

10x - 10y = -20

-10y = -20 - 10x

y = -20/-10 - 10x/-10

y = 2 + x

-10x + 4y = -16

-10x + 4(2 + x) = -16

-10x + 8 + 4x = -16

-6x = -24

x = -24/-6

x = 4

y = 2 + x

y = 2 + 4

y = 6

Solution = (4,6)

Step-by-step explanation:

Answer:

50=0.75x

Step-by-step explanation:

0.75 is how much each ticket costs.

x is how many tickets

50 dollars is how much you make.

We put 0.75 and x together since they both depend on each other.

y=mx+b

50=0.75x

The equation representing the total money in selling the tickets is

y = 0.75x + 50 where y is the total money and x is the number of tickets sold.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, you are selling tickets, you make $50 for signing up to sell tickets, and you also make $0.75 for each ticket you sell.

The slope-intercept form of an equation is;

y = mx + c, where m is the slope of the line.

Let y represents the total money earned for selling the tickets and x be the number of tickets sold.

The equation will be;

y = 0.75x + 50, where 0.75x is cost for selling x tickets and 50 is fixed amount.

Hence, The equation representing the total money in selling the tickets is y = 0.75x + 50 where y is the total money and x is the number of tickets sold.

Using proportions, it is found that the hedgehog loses 3.45 ounces after 115 days of hibernation.

A proportional relationship is modeled by:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, the ratio between the weighs loss after x days in hibernation is given by:

[tex]k = \frac{0.24}{8} = \frac{0.84}{28} = \frac{2.25}{75} = \frac{2.79}{93} = 0.03[/tex]

Since this ratio is constant, the relationship is proportional, modeled by:

[tex]y = 0.03x[/tex]

The weight lost after 115 days of hibernation is y(115), hence:

[tex]y = 0.03(115) = 3.45[/tex]

The hedgehog loses 3.45 ounces after 115 days of hibernation.

Answer:

sin (32) = 8.5/x

Step-by-step explanation:

hypotenuse is opposite the right angle (x)

Looking at the 32° angle , the number 8.5 is the opposite 32° angle

Trig ratios are    sin ∠ =  opposite/hypotenuse

                           cos ∠ = adjacent/ hypotenuse

                           Tan ∠ = opposite/ adjacent

Answer:

1/2-x+6≥x-15

Step-by-step explanation:

Answer:

The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.

The equation   − 2 (  x  +  3  )  =  − 2 x  −  6  does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.

We have  − 2 (  x  +  3  )  means that each term inside the parenthesis should be multiplied with  − 2 , i.e.

− 2 (  x  +  3 )  =  − 2  ⋅  x  −  2  ⋅  (  +  3 )  =  − 2 x  −  6

Which is exactly what the right side says.

Any value of x will, therefore, fulfill this equation.

Answer:

10*pi+20

Step-by-step explanation:

The diameter is 20m. The perimeter can be split into the curve part and the diameter. The curve part is 1/2 the length of the circumference of the circle, which is 1/2 of 20*pi, which is 10*pi. So the perimeter is 10*pi+20

The minimum point of a parabola is its vertex.

The equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]

The minimum point of the parabola is given as:

[tex]\mathbf{Minimum = (1.5,-1.5)}[/tex]

This represents the vertex (h,k).

So, we have:

[tex]\mathbf{(h,k) = (1.5,-1.5)}[/tex]

A parabola is represented with the following equation

[tex]\mathbf{y =a(x -h)^2 + k}[/tex]

Substitute values for h and k

[tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]

Hence, the equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex], where a does not equal to 0

Step-by-step explanation:

1.

-1 + 2x = 9

to get the solution

2x = 10

x = 5

2.

4 = 8 - x

x = 8 - 4 = 4

x/4 = 1

we could also write this

4 = 8 - x | /4

1 = 2 - x/4

x/4 = 1

x = 4

Answer:

e = 3

Step-by-step explanation:

we need to do inverse operations

6 + 6 = 12

12 divided by 4 = 3

e = 3

Check:

4(3) - 6 = 6

Answer:

e = 3

Step-by-step explanation:

The first step in solving an equation that has a variable is to isolate it. The variable is the unknown number and it is usually what you are trying to find the value of (x is the sign most used to represent a variable).

In order to isolate the variable in the equation 4e - 6 = 6, add 6 to both sides of the = sign:

4e - 6 = 6

   + 6 = + 6

4e - 6 + 6 = 6 + 6

We add 6 because doing so will cancel out the -6, leaving only e.

4e = 12

Now, because the question is asking for the value of e and not 4e, the next step is to divide both sides by 4:

[tex]\frac{4e}{4}[/tex] = [tex]\frac{12}{4}[/tex]

After dividing, the equation is shown as e = 3, which would be your answer.
