Therefore in this question the solution of particular equation is  108 children and 175 adults in the amusement park on that particular day.

When two expressions' values are set to be equal by a mathematical statement, that statement is known as an equation. To put it another way, it is a mathematical expression that means "this is equivalent to that." An equal sign, a mathematical expression, and a mathematical expression can all be seen on the left side of the symbol. The right ride of the equation frequently contains zero.

Let's first configure our system by giving x and y meaningful definitions. Let x be the total number of kids and y be the total number of adults.

Children cost $1.50, while adults cost $4.00. The number of kids, x, is multiplied by 1.5 to determine how much money a group of kids will cost. The 1.5x symbol stands for this. We will use 4y for adults, who must pay $4 to enter. On the specified day, $862 in total revenue was earned. We must add 1.5x and 4y to get at this sum.

1.5x + 4y = 862 equation required

Second equation: The total number of individuals present on the day is 283. X and Y, or the number of children and adults, must be added together to arrive at this figure.

x + y = 283

System of equations:

1.5x + 4y = 862

x +   y = 283

Thus,

x + y = 283  

y = 283 - x

Substitute y = 283 - x

862=1.5x + 4 (283 - x)  

1.5x + 1132 - 4x = 862

1132 - 2.5x = 862          

-2.5x = -270                  

x = 108

Substitute x =108 back into y = 283 - x

y = 283 - 108 = 175

Therefore there were 108 children and 175 adults in the amusement park on that particular day.

The correct option is option A

The volume of any object is the capacity. How much it can hold.

The formula of volume is a product of length, breadth and height.

Volume = L × B × H

Given:

The perimeter of the square base of side s plus height h = 250cm

as per the given question,

The perimeter of the square base of side s plus height h = 250cm

2( s + s ) + h = 250

2 (2s) + h = 250

4s + h = 250

We can express h in the terms of s as,

h= 250 - 4s

Volume = length X breadth X height

Volume = s × s × h

V = s² × h

V = s² × (250 - 4s)

V = 250s² - 4s³

Answer:

$40.63

Step-by-step explanation:

If the phone company charges $17.75 already, and each minute costs $0.13, then we can do an equation that looks something like this:

17.75 + (0.13 × 176) = total price

We need to figure out how much 0.13 multiplied by 176 is.

0.13 × 176 = 22.88

Now that we figured out that 0.13 multiplied by 176 is equal to 22.88, we need to add the monthly access fee.

22.88 + 17.75 = 40.63

The monthly cost will be $40.63.

Answer:

slope 6

y intercept 4

y = 6x + 4

Step-by-step explanation:

The slope is the change in y over the change in x.  

Look at he two points (0,4) and (1,10)

The y started at 4 and went up to 10.  That is a distance of 6.

AT the same time, the x changes from 0 tp 1 (0,4) (1,10).  That is a distance of 1.

6/1 = 6

The y intercept is where the line crosses the y axis.  It crosses at (0,4).  4 is the y intercept

y = mx + b  Put the slope is for m and the y intercept for b

Answer: y=−2x+16

Step-by-step explanation:

To solve for x, we need to isolate x on one side of the equation. To do this, we can first move all the terms that do not contain x to the right side of the equation by adding 3x and 2 to both sides:

2x - 2 + 3x + 2 = -3x + 13 + 3x + 2

5x = -3x + 15

8x = 15

Dividing both sides by 8, we get:

x = 15/8

= 1.875

Therefore, the value of x is approximately 1.875.

The value of x in equation 2x-2= -3x+13 is 3

To solve this equation we need to find the value of x so that all x terms should be one side and all constants should be at ones side:

2x+3x=13+2

5x=15

Now divide both side with 5 then, we get:

5x/5=15/5

x=3

The pressure of 28 inches of mercury occurs about 6 miles from the eye of hurricane.

In essence, atmospheric pressure is the force that the weight of the air above a particular point on the Earth's surface exerts at that location.

In other words, the weight of the air molecules as a whole determines the atmospheric pressure, which is produced by the air that surrounds the Earth.

Lower pressure is felt by air molecules at higher altitudes because there are fewer molecules pressing down on them from above, while higher pressure is felt by air molecules at lower altitudes because they are closer together and are under more pressure from molecules piled on top of them.

F(x) is the pressure in inches of mercury

It is given pressure 28 inches of mercury

Put F(x) equal to 28

F(x) = 0.48㏑(x+2) +27

28 = 0.48㏑(x+2) + 27

28-27= 0.48㏑(x+2)

1= 0.48㏑(x+2)

1/0.48= ㏑(x+2)

25/12= ㏑(x+2)

x+2= [tex]e^{\frac{25}{12} }[/tex]

The required simplification of given function is [tex]\frac{(x-1)^{2}}{x-2}[/tex] and restriction on domain are x  ≠ 1, 2.

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

We have,

[tex]\frac{(x+3)(x-1)}{x-2}[/tex] ÷ [tex]\frac{x+3}{x-1}[/tex]

[tex]\frac{(x+3)(x-1)}{x-2}[/tex] × [tex]\frac{x-1}{x+3}[/tex]

[tex]\frac{(x-1)^{2}}{x-2}[/tex]

For domain, Function should have solution should not be not defined.

For this, denominator must not equal to zero

Then, x -2 ≠ 0, x - 1  ≠ 0

x  ≠ 2, x  ≠ 1

Thus, option(3) [tex]\frac{(x-1)^{2}}{x-2}[/tex] x  ≠ 1,2 is correct.

Step-by-step explanation:

You want to know the domain restrictions and the simplified form of ...

  [tex]\dfrac{(x+3)(x-1)}{(x-2)}\div\dfrac{x+3}{x-1}[/tex]

We can "invert and multiply", then cancel the common factor from numerator and denominator.

  [tex]\dfrac{(x+3)(x-1)}{x-2}\div\dfrac{x+3}{x-1}=\dfrac{(x+3)(x-1)}{x-2}\times\dfrac{x-1}{x+3}=\dfrac{(x+3)(x-1)^2}{(x+3)(x-2)}\\\\=\dfrac{(x-1)^2}{x-2}\qquad x\ne -3[/tex]

The values of x that must be excluded from the domain are those values for which any part of this expression is undefined. The expression is undefined when any denominator is zero: at x = 2 (left "factor"), at x = 1 (right "factor"), and at x = -3.

The factor (x +3) doesn't show up in the simplified form, but it is a "hole" in the graph of the original expression—a value of x where the function is not defined.

Here is a summary of what you get at the restricted values:

The x - intercept is (25, 0) and the y - intercept is (0, 10).

What is intercepts?

The x-intercept and y-intercept are the points at which a line crosses the x- and y-axes, respectively.

Put y = 0 and work out x to find the x-intercept.

Set x = 0 and work out y to find the y-intercept.

Given: You are ordering shirts for the math club at your school.

Short-sleeved shirts cost $ 8 each.

Long-sleeved shirts cost $ 20 each. You have a budget of $ 200 for the shirts.

The equation 8 x+20 y=200 models the total cost,

where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.

To find the x - intercept plug y = 0 in the above equation.

⇒ 8x + 20(0) = 200

                8x = 200

                  x = 25

So, the point becomes, (25, 0).

To find y - intercept plug x = 0 in the above equation.

⇒ 8(0) + 20y = 200

              20y = 200

                  y = 10

So the point becomes, (0, 10).

Hence, the x - intercept is (25, 0) and the y - intercept is (0, 10).

The second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

The equation of the form ax² + bx +c is known as a quadratic equation.

Given that, the zeros of the quadratic function are -7 and 1 and include the point (2,27/2).

Substitute x = 1 into the given inequality to check whether any of them becomes less than 0 or not:

From the first inequality:

y < -3/2 + 9 + 21/2

y < 18

From the second inequality:

y < 3/2 + 9 -21/2

y < 0

Since the inequality is less than 0, it is also less than the quadratic function at x = 1.

Similarly, checking the third inequality also gives y < 0, but the fourth doesn't.

Now, from the second and the third inequality, check which one is less than 27/2 for x = 2:

From the second inequality:

y < 6 + 18 -21/2

y < 27/2

From the third inequality:

y < -6-9+21/2

y < -27/2

Since the second inequality, y < (3/2)x² + 9x -21/2, is less than 0 at x =1 and less than 27/2 at x=2, it is also less than the quadratic function whose zeros are -7 and 1 and includes the point (2,27/2).

Hence, the second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).
