Find the values of x and y. The diagram is not to scale

Answer:   (4b, -3a)

Reason:

When reflecting over the line y = x, we swap the positions of the x and y coordinates.

The reflection rule is [tex](\text{x},\text{y}) \to (\text{y},\text{x})[/tex]

The required linear function y = -x + 2.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

The equation for the slope, m, of a line is:

m = y₁- y₀ / x₁ - x₀                         {equation 1}

The equation f(0) = 2 tells us that x₀ = 2and y₀ = 0,

substitute this into equation [1].

m = y₁- (0) / x₁ - 2                         {equation 2}

The equation f(3) = -1 tells us that x₁ = -1 and y₁= 3,

substitute this into equation [2].

m = 3/-3

m = -1

Substitute m to the equation y = mx + b,

y = -x + b

Now, substitute the value of x = 2 and y = 0

b = 2.

Now the linear function,

y = -x + 2

Therefore the linear function y = -x + 2.

The amount for handle soend on Christmas present will be 240.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Hadlee spent 1/4 of her money on Christmas presents she had 180 remaining.

Now,

Since, Hadlee spent 1/4 of her money on Christmas presents she had 180 remaining.

Let the amount for handle soend on Christmas present = x

Hence, The amount for handle soend on Christmas present will be;

⇒ x - 1/4x = 180

⇒ 3/4x = 180

⇒ 3x = 180 × 4

⇒ 3x = 720

Answer:

m∠5 + m∠6 =180°

m∠2 + m∠3 = m∠6

m∠2 + m∠3 + m∠5 = 180°

Step-by-step explanation:

m∠5 + m∠6 are linear pairs, so their sum has to be 180°.

m∠2 + m∠3 = m∠6 because of the exterior angle theorem, which states that the measure of an exterior angle is equal to the sum of the two opposite interior angles. (using this logic, m∠1 equals the sum of m∠5 and m∠3, and m∠4 equals the sum of m∠2 and m∠2).

m∠2 + m∠3 + m∠5 = 180° because the triangle sum property says that the sum of a triangle's interior angles will equal 180°.

Answer:

The answer should be A.

Step-by-step explanation:

The correct statement according to the given equation is statement (D)"They have a single solution since they have various y-intercepts but the same slopes."

The relationship between two terms on either side of an equal sign is easily demonstrated using a simple equation.

Additionally, one or more of the four arithmetic operations that simple equations do include addition, fundamental arithmetic, multiplication, and division.

The three possible forms of the equation system are point-slope form, standard form, and slope-intercept form.

So, given equations:

y = 1/2 * x - 3

y = - 1/2 * x - 3

As we are aware, a line's slope-intercept form is:

y = m x + c  

Therefore, it is clear from equations 1 and 2 that:

m1 = 1/2 and c1 = -3

m2 = -1/2 and c2 = -3

Therefore, the correct statement according to the given equation is statement (D)"They have a single solution since they have various y-intercepts but the same slopes."

a. They have the same slope but different y-intercepts, so they have no solution.

b/. They have the same slope but different y-intercepts, so they have one solution.

c. They have different slopes but the same y-intercept, so they have no solution.

d. They have different slopes but the same y-intercept, so they have one solution.

Answer:

(1, - 1 )

Step-by-step explanation:

x + y = 0 → (1)

5x + y = 4 ( subtract 5x from both sides )

y = 4 - 5x → (2)

substitute y = 4 - 5x into (1)

x + 4 - 5x = 0

4 - 4x = 0 ( subtract 4 from both sides )

- 4x = - 4 ( divide both sides by - 4 )

x = 1

substitute x = 1 into (1) and solve for y

1 + y = 0 ( subtract 1 from both sides )

y = - 1

solution is (1, - 1 )

If the surface area of the rectangular box is 4 m² then the dimensions that maximize its volume is  (2/√3 , 2/√3 , 1/√3)  .

In the question ,

let length of rectangular box be = l

let width of rectangular box be = b and

let height of rectangular box be = h .

Since the box has no top ,

So , the surface area is = lb + 2bh + 2hl = 4

we get h = (4-lb)/(2l + 2b) .

The volume of the box is given as  V = l×b×h .

Substituting the value of h from above in the volume formula , we get ,

V = lb(4-lb)/(2l + 2b)

differentiating it with respect to l ,

we get ,

dV/dl = [((2l+2b)(4b-2lb²)-lb(4-lb).2)/(2l+2b)²] = 0

Simplifying further ,

we get ,

2l² + 4lb - 8 = 0       ....equation(1)

Differentiating volume with respect to "b" .

dV/db = [((2l+2b)(4l-2l²b)-lb(4-lb).2)/(2l+2b)²] = 0

simplifying further ,

we get ,

2b² + 4lb - 8 = 0        ...equation(2) .

Simplifying equation(1) and (2) , we get

l = b  ,

Substituting l = b in equation(1) ,

we get ,

2l² + 4l² = 8

l = 2/√

and b = 2/√3 .

Substituting the values in h ,

we get ,

h = (4-lb)/(2l + 2b)

h = 1/√3 .

The solution of the inequality 9x + 6  ≥  132 and -7x + 19 < -128 is x ≥ 14 and x > 21.

Compound inequalities are a type of inequality that has two or more parts.

In other words, a compound inequality is an inequality that combines two simple inequalities.

Therefore, let's solve the compound inequality as follows:

9x + 6 ≥ 132 and -7x + 19 < -128

Let's solve them independently.

9x + 6 ≥ 132

subtract 6 from both sides of the inequality

9x + 6 ≥ 132

9x + 6 - 6 ≥ 132 - 6

9x ≥ 126

divide both sides by 9

x ≥ 126 / 9

x ≥ 14

-7x + 19 < -128

subtract 19 from both sides of the inequality

-7x + 19 - 19 < - 128 - 19

-7x < - 147

Insurance Premium:

A premium is the amount an individual or business pays for an insurance policy. Premiums are paid for policies that cover health insurance, auto insurance, home insurance, and life insurance. When the premium is paid, it becomes income for the insurance company. It also constitutes liability, as the insurer must pay for claims arising from the policy. Failure to pay individual or corporate premiums may result in the cancellation of the policy.

The insurance company actuary is responsible for determining premium payments using statistics and calculations. Determine the likelihood of encountering an event or accident requiring insurance coverage. We will also be charged for any costs associated with the coverage.

Using the above factors to determine the premium, the actuary determines the price charged by the insurance company so that the amount the actuary receives is greater than the amount the company has to pay for the claim. increase.

Information gathered by actuaries is entered into tables called actuarial tables and passed on to insurance companies who set premium prices.

Congruent triangle: The values of x, y, and z are x = 23; y = 7 and z = 11.

What is a congruent triangle?

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent.

Given: ΔPRS ≅ ΔCFH

Since both triangles are congruent, m<R = m<F

m<F is a right angle = 90°.

Thus, 13y - 1 = 90

13y = 90 + 1

13y = 91

y = [tex]\frac{91}{13}[/tex]

y = 7

Also, by inspection

PS = CH

⇒ 2x - 7 = 39

⇒ 2x = 39 + 7

⇒ 2x = 46 ⇒ x = [tex]\frac{46}{2}[/tex]

x = 23

Since m<R is 90°, then

m<S = 180 - (90 + 28)

m<S = 62°

By inspection,

m<S = m<H

Thus,

⇒ 6z - 4 = 62

⇒ 6z = 66

z = [tex]\frac{66}{6}[/tex]

z = 11
