The function x = 10y + 30 where x is the total amount paid and y is the number of hours.

The babysitter is paid $30 each week for driving the children to school and $10 for each hour she watches them.

Let x represent the total amount paid to the babysitter in a week.

Let y be the number of hours the babysitter watched the kids.

The function that represents the situation will be:

The total amount paid = Pay each week + Pay for the number of hours the babysitter watched the kids.

x = 30 + 10 × y

x = 10y + 30

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Store sells 630 calendars in a week for the price is $14.30.

Now,

Since, Store sells 630 calendars in a week for the price is $14.30.

So, We can formulate;

Number of sell if raises the price is $17.80 is;

= 630 x $14.30 / $17.80

Multiply the number, we get;

= $9,009 / $17.80

Divide the numbers, we get;

= 506

The values of p and q so that the equations has infinitely many solutions are -12 and 4 respectively.

Given, we have equation px+4=-12x+q

To  find the values of p and q we just need to equate coefficients of corresponding terms.

To find q, substitute p = -12

-12x+4=-12x+q

-12x+12x+4 = q

q = 4

hence when q = 4, then

px+4 = -12x+4

px+4 - 4 = -12x

px = -12x

p = -12

Therefore, for infinitely many solutions of the equation, the values of p and q are -12 and 4 respectively.

Hence tha values of p and q are -12 and 4.

The value of m∠L is 55 degrees and the value of m∠J  is 61 degrees.

As we know, vertical angles are the opposite angles made by the intersection of the two lines, vertical angles are equal in magnitude,

So, we can write,

1. ∠L and ∠Z are vertical angles,

∠L = 2x + 9 and,

∠Z = 3x - 14.

Because both are vertical angles, so,

∠L = ∠Z

2x + 9 = 3x - 14

Solving further,

3x - 2x = 9 + 14

x = 23

So, the value of ∠L is,

= 2(23)+9

= 46+9

= 55°

The value of angle ∠L is 55°,

2. As, ∠Y and ∠J are vertical angles, so they are equal,

∠Y = 7x + 12

∠J = 10x - 9

∠Y = ∠J

7x + 12 = 10x - 9

Solving further,

3x = 21

x = 7

So, the value of ∠J is,

= 10(7) - 9

= 70 - 9

= 61°

The value of ∠J is 61°.

Remy will still get 370270

What is subtraction?

At first it is important to know about integers.

Integers are numbers which have no fractional part.

Integers can be positive, negative and zero is also an integer.

Now, to find the difference between two integers, subtraction is used.

The larger number is called minuend and the smaller number is called subtrehend.

Here,

Amount of money Remy lent = 1248500

Amount of money Remy could able to collect = 878230

Amount of money Remy will get = 1248500 - 878230

Step-by-step explanation:

The ordered pair (3,4) in relation to origin is plotted as:

3 spaces to the right and 4 spaces up

When two items are written inside parantheses and are separated by a comma, they create an ordered pair. For instance, the ordered pair (x, y) indicates an ordered pair in which 'x' is referred to as the first element and 'y' is referred to as the second element. These items, which can be either variables or constants, have distinct names depending on the context in which they are used. In an ordered pair, the element order is somewhat significant. It implies that (x, y) may not always be equivalent to (y, x).

In coordinate geometry, a point's location on the coordinate plane with respect to the origin is represented as an ordered pair. Two perpendicular intersecting lines, one of which is the x-axis and the other is the vertical line, together constitute a coordinate plane (y-axis).

Answer:

30 movies.

Step-by-step explanation:

Hey! Let's help you with your question here!

Alright, so here's what we know. When we go see a movie, we earn 2 advantage points. We need 100 points to get a free movie pass and we currently have 40 advantage points.

When writing equations like this, we need to know what the fixed values and the variable values are. The variable values are subject to change, where the fixed values, we cannot change.

In this question here, we have 40 advantage points and this is already given to us, so it cannot change. This is our fixed value. What we can change is how many times we can see a movie after that, which will earn us 2 advantage points each time. This will be our variable value.

Now that we've determined our values, let's create the formula! I will be using y to represent the total amount of points and m to represent the amount of movies seen. So, we write it as such:

[tex]y=2(m)+40[/tex]

We got our formula! Now we have to figure out how many more movies we need to watch to get our free movie pass. Since we know that is the total amount of points that we need to get, we can substitute 100 into y to solve for m which is the number of movies! It would look like this:

[tex]100=2(m)+40[/tex]

[tex]60=2(m)[/tex]   - We move 40 over to the left side and subtracted 100 by 40.

[tex]\frac{60}{2}=\frac{2(m)}{2}[/tex]    - We divide both sides by 2 to get rid of the 2 in front of the m.

[tex]30=m[/tex]

And there we have it! We would need to see 30 movies in order to get our free movie pass! You can double check this by taking [tex]y=2(m)+40[/tex] and substitute m with 30 and find y.

The missing reasons in each of the steps involved in solving the one-variable equation are as follows;

It follows from the task content that the steps which are missing be determined.

Part A; we have;

2 { (1/2)x - 5} = 20

It follows that the expression above is derived by multiplying both sides of the equality by 2. Hence, the missing reason is; The multiplication property of equality.

Part B; Since the equation; 2 { (1/2)x - 5} = 20 is rewritten as; x - 10 = 20.

It follows that each term in the parentheses is multiplied by 2 and this concept is best described by the distributive property.

Part C; Finally, 10 is added to each side of.the equality; x - 10 = 20 which results in; x = 30.

The scenario above is best modelled by the addition property of equality.

The exact value of the trigonometric function sec θ is 17/15.

When a number or algebraic expression is beneath a radical, the form is referred to as being in radical form. However, by rearranging a number or algebraic expression in radical form into what is known as the simplest radical form, we can improve that.

The angle θ in standard position and the terminal side passes through the point ( 15, 8 ).

So, we have x = 15 and y = 8 which is in the first quadrant.

Therefore,

r² = x² + y²

r² = ( 15 )² + ( 8 )²

r² = 225 + 64

r² = 289

r = 17

Then,

sec θ = 1/cosθ

sec θ = [ 1/(x/r) ]

sec θ = r/x
