The linear equation that has the desired characteristics is given by:

y = -2.5x.

The graph is given at the end of this question.

A linear function is modeled by:

y = mx + b

In which:

If two lines are parallel, they have the same slope, which is given by change in y divided by change in x, hence:

m = (-3 - 2)/(-4 - (-6)) = -5/2 = -2.5.

Hence:

y = -2.5x + b.

The line also passes through (2,-5), that is, when x = 2, y = -5, hence we use it to find b.

-5 = -2.5(2) + b

b = 0.

Hence the equation is:

y = -2.5x.

Algebraically, the amount of money the insurance company will pay, represented as P, is equal to the total value of the stolen items (2b + t) minus the deductible (d).

Let's denote the amount of money the insurance company will pay as P. In this scenario, if the value of the stolen items is greater than the deductible, the insurance company will cover the loss, and Ron will receive compensation for the stolen items.

The total value of the stolen items can be calculated by adding the value of the bicycles (2b) and the value of the tools (t). So, the total value of the stolen items is 2b + t.

If the total value of the stolen items is greater than the deductible (d), then the insurance company will pay the difference between the total value and the deductible. Mathematically, this can be represented as:

P = (2b + t) - d

Therefore, algebraically, the amount of money the insurance company will pay, represented as P, is equal to the total value of the stolen items (2b + t) minus the deductible (d).

Answer:

96

Step-by-step explanation:

10 x 8 = 80

2 x 8 = 16

so 80 + 16 = 96 :)

The equivalent value of the equation is A = 96

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 12

Let the second number be q = 8

Now , A = pq

On simplifying the equation , we get

A = 12 x 8

So , the left hand side of the equation is equated to the right hand side by the value of 12 x 8

On multiplying 12 times 8 , we get

A = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8

A = 96

Therefore , the value of A = 96

Hence , the expression is A = 96

Step-by-step explanation:

For the given function, the critical point is (-1,2), relative extrema is is 2, and saddle points is zero.

To find the critical points of a function, we need to find where the partial derivatives of the function are equal to zero or do not exist. In other words, we need to find the points where the function is not changing with respect to x and y. The partial derivative of f(x,y) with respect to x is:

fx = 2x + 2

And the partial derivative of f(x,y) with respect to y is:

fy = 2y - 4

To find the critical points, we set both partial derivatives to zero and solve for x and y:

fx = 2x + 2 = 0

=> x = -1

fy = 2y - 4 = 0

=> y = 2

So, the critical point of the function is (-1, 2).

To determine whether this critical point is a relative maximum, minimum, or saddle point, we need to look at the second partial derivatives of the function. The second partial derivative of f(x,y) with respect to x is:

fx = 2

And the second partial derivative of f(x,y) with respect to y is:

fy = 2

The mixed partial derivative of f(x,y) with respect to x and y is:

fy = 0

To classify the critical point, we can use the second derivative test.

If fx and fy are both positive (or both negative) at the critical point, then the critical point is a relative minimum (or maximum), respectively.

If fx and fy have different signs, then the critical point is a saddle point. If the second derivative test is inconclusive, then we need to use additional methods to determine the nature of the critical point.

The statements that will be true about parallelogram ABCD are: A, B, D, and E.

Properties of a Parallelogram -

Diagonals of a parallelogram bisect each other into congruent segments.

Opposite angles and sides of a parallelogram are always congruent.

Alternate interior angles are always congruent in measure.

Thus, the following would be true of parallelogram ABCD:

AP ≅ CP (congruent segment's of a bisected diagonal)

BC ≅ AD (congruent opposite sides)

∠CAD ≅ ∠ACB (congruent angles)

∠BPC ≅ ∠APD (congruent angles)

Answer:

169

Step-by-step explanation:

x²+26x=23

=> to complete the square, the equation should be : x²+26x + (26/2)² = 23 + (26/2)²

<=> x² +26x + 13² = 23 + 13²

<=> x² +26x +169 = 23 + 169

<=> (x+13)² = 192

so, (x+13)² is the square form , and 169 must be added to complete the square

For 2ab to complete in (a+b)² formula

a=1

So 169 must be added

Therefore , the solution of the given problem of area comes out to be

r = 8.

The term "area" describes the amount of space occupied by a 2D form or surface. We use cm2 or m2 as our units for measuring area. A shape's area is determined by dividing its length by its breadth.

Here,

A 90 degree sector occupies 1/4 of a circle, which has 360 degrees. Consequently, the area of the whole circle can be written as

Sector Size/Sector Area = Circle Area/360

16 ft2/90 = n/360

(360) (16 ft2)/90 = n

(4)(16 ft2) = n

The total size of the circle is n = 64 ft2.

Since Area of a Circle equals r2,

∏r2 = 64

r2 = 64/∏

r = √(64/∏)

We multiply by / to get by rationalizing the denominator.

r = √(64∏)/√(∏2) Then using the denominator's square root, we can obtain the solution of

r = √(64∏)/∏

r = 8

Therefore , the solution of the given problem of area comes out to be

r = 8.

Answer:

208 cubic units

Step-by-step explanation:

The composite figure in the picture is composed of a triangular prism and a rectangular prism, both which can be calculated by the base * height formula.
First, let’s calculate the volume of the triangular prism:

The base is the area of the triangle base, which is dc/2, or 4*3/2, which is 6. Next, multiply the area of the base by the height “b”: 6 * 8 = 48.

Now, let’s calculate the volume of the rectangular prism:

The base is the rectangular base’s area, which is a*c, or 5*4, which is 20. Next multiply the base by the height “b”: 20 * 8 = 160

Now, add up the volumes of the rectangular and triangular prisms:

160 + 48 = 208 cubic units

Answer: There are two ways to find maximum profit: with a graph, or with calculus.

Graphically, you’re looking for a global maximum.

A global maximum is the maximum over the entire range of the what is a function. On a graph, that’s the highest peak.

Local maximums happen at inflection points (where the graph changes direction).

At the maximum of a function, the gradient or slope of the function is zero. With calculus, you can find the derivative of the function to find points where the gradient (slope) is zero, but these could be either maxima or minima.

If the slope is increasing at the turning point, it is a minimum.

If the slope is decreasing at the turning point, then you have found a maximum of the function.

The simplified expression involving complex numbers is given as follows:

5 + 5i.

Complex numbers are number that have a real and an imaginary part, and are defined as follows:

z = a + bi.

In which:

The basic relation of complex numbers is given as follows:

i² = -1.

The fraction for this problem is given as follows:

(2 + i)(4 - 2i)/(1 + i).

The numerator is simplified as follows:

(2 + i)(4 - 2i) = 8 - 4i + 4i - 2i² = 8 + 2 = 10.

Hence the fraction is of:

10/(1 + i).

To remove the complex number from the denominator, the entire fraction is multiplied by the conjugate of the denominator, hence:

10/(1 + i) x (1 - i)/(1 - i) = 10(1 + i)/(1 - i²) = 10(i + 1)/2 = 5 + 5i.

Answer:

y-4=-7(x-(-10))

y=-7x-66

Step-by-step explanation:

Solving a system of equations we can see that the washer costs $750, and the dryer costs $250.

Let's define the variables:

x = cost of the washer.

y = cost of the dryer.

We know that the cost combined is $1000, then:

x  + y = 1000

And the washer cost 3 times the cost of the dryer, then we will get:

x = 3y

So we have a system of equations, we can replace the second equation into the first one, so we will get:

3y + y = 1000

4y = 1000

y = 1000/4

y = 250

The cost of the washer is:

x = 3*250 = 750

Answer:

286

Step-by-step explanation:

Given :

Mean (m) = 284

Standard deviation (s) = 5.5

P(Z > x) = 0.34

According to the standardized formula :

Zscore = (x - m) / s

Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412

Hence, Zscore = 0.412

Zscore = (x - m) / s

0.412 = (x - 284) / 5.5

5.5 * 0.412 = x - 284

2.266 = x - 284

x = 2.266 + 284

x = 286.266

x = 286 (nearest whole number)
