what is the ordered pair for the equation -7x+3y=2​

The number of fidgets and pop bought was 15 each

From the information given, we have that;

1 fidget costs $3

1 Pop cost $4

Let the number of Fidgets be x

Let the number of Pop be y

Then, we have that a total of 20 fidgets and Pop cots $75

We have that;

20x + y = 75

Now, substitute the value of x as 3, we get;

20(3) + y= 75

expand the bracket

y = 75 - 60

y = 15

The number of fidgets is expressed as;

20x/4 = 20(3) /4 = 15

The required direction of the inequality is below the line.

If you're not graphing a vertical line, the inequality's sign will tell you which half-plane to shade. Shade above the line when using the  or > sign. Shade below the line if the symbol or is used. Larger solutions are to the right and smaller solutions are to the left, respectively, for a vertical line.

To check the direction, we will take points from the graph and put in the given inequality.

At point (2, 0)

y ≤ x/4 - 3

0 ≤ 2/4 - 3

0 ≤ -25

It is false

Again

At (2, -4)

y ≤ x/4 - 3

-4 ≤ 2/4 - 3

-4 ≤ -2.5

It is true,

Thus, we can say the direction of the inequality is below the line.

A transformative sequence is a particular arrangement of transforming events. This suggests that a series of transformations may manage more than one transition, and that the order in which they occur is crucial. A and B are similar in this case.

When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.

Formally, two sets of points are said to be congruent if, and only if, an isometry, which is a collection of rigid motions including translation, rotation, and reflection, can transform them into one another.

This shows that resizing an object will not allow it to be properly aligned with another object, only by moving and reflecting it. Therefore, two independent plane figures on a piece of paper are congruent if we can cut them out and then precisely line them up. The paper might be distributed.

Each box is the same size in terms of length and width. The only change is where the figure is located.

Transformations can be divided into four categories: translation, rotation, reflection, and dilation.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Congruent refers to things that are exactly the same size and shape.

Hence, A and B are congruent.

Using Vieta's Theorem the value of c = 72.

Suppose we have a quadratic equation, in the following format:

ax² + bx + c, were a, b, and c are constant.

The roots are p and q.

As, The Theorem states that:

p + q= -b/a

pq= c/a

We have given the polynomial  x²-17x+c=0

So, a= 1, b= -17

Since the difference of the solutions is 1, we have that:

p -q= 1

p = 1+ q

Now, using p + q= -b/a

1 + q + q= -(-17)/1

2q +1 = 17

2q= 16

q= 16/2

q= 8

and, p = 1+ q= 9

Again pq = c/a

8 x 9 = c/1

c= 72

The value of the expression 18 + 4(28) will be 130.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ 18 + 4(28)

Simplify the expression, then the value of the expression will be

⇒ 18 + 4 x (28)

⇒ 18 + 4 x 28

⇒ 18 + 112

⇒ 130

Thus, the value of the expression 18 + 4(28) will be 130.

The required result of the identity is \(x^{2} =-y^{2}-2x+16y-56\).

To isolate the algebraic expression given below we need to simplify it and then make \(x^{2}\) the subject of the equation,

For that we must know the identity \((a+b)^{2}=a^{2}+2ab+b^{2}\).

We will break the given equation on the basis of the given identity.

Now, \((x+1)^{2} +(y-8)^{2}=9\\\)

     ⇒\(x^{2} +2x+1+y^{2}-16y+64=9\\\)

     ⇒ \(x^{2} =-y^{2}-2x+16y-56\)

So, the required result of isolating the above given equation is as above.

As a fraction of 100, a percentage is a number or ratio. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A % has no dimensions and no associated unit of measurement.

Light-at-Dawn: A 1-gallon can normally costs $24, however it is now on sale for 25% less than that amount. This kind of paint needs two coats.

Cloudy Sunrise: A gallon-sized can costs $28. Only one coat of this kind of paint is necessary.

350 square feet will be covered by each gallon at a time.

The price of 1 gallon of light at dawn is 24 - 25/100 * 24 = 18.

1 gallon of clouded sunrise color costs 28 dollars.

It appears overcast. Prior to accounting for the number of square feet that each hue may cover, sunrise color is more expensive.

350 square feet are claimed to be covered by both cans.

if everything else remains the same,.

Dawn color lighting would cost:

18 / 350, or.0514285714, per square foot.

However, the light at dawn color needs two coats.

The total cost per square foot for the light at dawn color would be

2 * 0.0514285714 = 0.1028571429.

The price of a cloudy sunrise is 28/350 = 0.08 per square foot.

This represents the total cost per square foot for cloudy sunrise color since it only needs one coat.

It looks that the total cost of cloudy sunrise color is less expensive than the total cost of light at dawn color, assuming that the second coat of paint uses the same amount of paint as the first coat.

Hence, The paint should be used is Cloudy Sunrise
