PLEASE HELP ASAPwhich Expression Can Be Used To Find The Sum Of The Polynomials?

Answers

Answer 1

The correct expression to solve te sum of polynomials is [(-3x)+(-8x)]+4x+[9+5] (D).

To solve any polynomials problems, it is important for us to take a close look on the orders of each number. For the sum and substraction operation, we need to categorize each number based on its orders.

From the case, we have a problem as:

(9 - 3x²) + (-8x² + 4x  + 5)

We can categorize each order:

Order 2 = (-3x²) and (-8x²)

Order 1 = 4x

Order 0 = 9 and 5

Hence, we can solve the problem as:

(9 - 3x²) + (-8x² + 4x + 5)

= [(-3x²) + (-8x²)] + 4x + (9 + 5)

= -11x² + 4x + 14

What is an example of no solution?.

Answers

The system of equations x + 2y = 3, 2x + 4y = 15 is an example of no solution.

If (a₁/a₂) = (b₁/b₂) ≠ (c₁/c₂), then there will be no solution. This sort of system of equations is called an inconsistent pair of linear equations. If we plot the graph, the lines will be parallel, and the system of equations has no solution.

Given equations are x + 2y = 3

2x + 4y = 15

a₁ = 1, b₁ = 2, c₁ = -3

a₂ = 2, b₂ = 4, c₂ = -15

a₁/a₂ = 1/2

b₁/b₂ = 1/2

c₁/c₂  = 1/5

a₁/a₂ = b₁/b₂ ≠ c₁/c₂

So, the system of equations has no solution.

(-2, 6)

(1, 4)

Answer:

Correct choices are:

(-1, 8)

(1, 4)

which would correspond to the second and fourth entries of your options

Step-by-step explanation:

Best way to solve this problem is to plug in x and y values for each ordered pair and see if these values result in a consistent equation. It is impossible to solve the equation since there are two unknowns and only one equation

Here is each ordered pair and resulting y value when x value is plugged in

(-1, 2) ==> y = 2, x = -1
6 - 2(-1) = 6 + 2 = 8
This is not equal to the given value of y =2. So incorrect

(-1, 8)
We figured out from above that when x = -1, y = 8 so this is a correct choice

(-2, 6) ==> x = -2, y = 6

6 - 2(-2) = 6 + 4 = 10
Does not match y-value; incorrect

(1, 4) ==> x = 1, y = 4

6 - 2(1) = 6 - 2 = 4

This matches the given value of y so correct choice


Find the coordinates of P so that P partitions the segment AB in the ratio 3 to 1 if A(7, -4) and B(-5, 4). Show your work.

Answers

Answer: A partition of a line segment is a point that divides the segment into a certain ratio of segments. In this case, point P partitions the segment AB in the ratio 3 to 1.

To find the coordinates of point P, we can use the following method:

Let the point P be (x,y)

The ratio of the segments AP:BP is 3:1, so we can use the proportion: (AP)/(BP) = 3/(1+3) = 3/4

We can use the coordinates of points A and B to find the coordinates of point P. The x-coordinate of P is (3/4) times the difference in x-coordinates of A and B, plus the x-coordinate of A. And the y-coordinate of P is (3/4) times the difference in y-coordinates of A and B, plus the y-coordinate of A.

So, using the coordinates of A and B:

x = (3/4)(-5 - 7) + 7 = -4

y = (3/4)(4 - (-4)) -4 = 3

Therefore, the coordinates of point P are (-4,3)

a rectangular garden is 115 * 90 m.it has two roads, each 6 m wide, running in middle of it, one parallel to its length and other parallel to its breadth.find the cost of constructing the roads at $ 100 per m

Answers

Step-by-step explanation:

so, the first road is 115 m long, the second is 90 m long.

we should be finished, if we multiply each road length by $100, right ?

well, not quite.

because the 2 roads overlap. for this overlap area we don't need to pay twice.

we have the choice : to which of the 2 roads do we assign the overlap area ?

let's "give" it to the longer road.

so, the cost for the longer road is simply

115 × 100 = $11,500

the cost for the shorter road is then without the overlap area (6 meters : the width of the other road)

(90 - 6)×100 = 84×100 = $8,400

in total the costs are

$11,500 + $8,400 = $19,900

What are the vertices of a quadrilateral ABCD?

A(,3,8), B(6,-8), C(-6,-6) and D are the vertices of the quadrilateral ABCD (-3,4) Establish the rhombic shape of ABCD.

A polygon with four sides exactly is referred to as a quadrilateral. The fact that a quadrilateral has exactly four vertices and four angles is also implied by this.

What is an angle?

Two lines intersect at a location, creating an angle. An "angle" is the term used to describe the width of the "opening" between these two rays. Angles are frequently expressed in degrees and radians, a unit of circularity or rotation. We encounter angles frequently in life. Angles are used in the design of buildings, roadways, and sports venues by engineers and architects.

C,U and B are the angles and the  c,u and b are the sides opposite to the angles  C,U and B  respectively.

Law of cosines:

c² = u² + b² - 2ub cos C

58²=78²+48² - 2(78)(48) cos C

3364=6084+2304-7488 cos C

3364 = 8388-7488 cos C

=> 7488 cos C = 8388 - 3364 = 5024

=>  cos C = 5024 /7488 = 0.6709

=> C = arccos(0.6709) = 47.86⁰

What is the solution to the linear equation 2. 8 y 6 0. 2 y 5y 14 y 10 y 1 y 1 y 10?.

Answers

The equation you provided is a linear equation that can be solved by isolating the variable y on one side of the equation. To find the solution for y, we need to follow these steps

First, we will simplify the equation by combining like terms: 2.8y + 0.2y = 5y – 14 + 6 3y = 5y – 8

Next, we need to get y alone on one side of the equation by subtracting 3y from both sides: 0 = 2y - 8

We will add 8 to both sides of the equation: 8 = 2y

Finally, we will divide both sides of the equation by 2 to find the solution for y: y = 4

So the solution for the linear equation 2.8y + 6 + 0.2y = 5y – 14 is y=4.

A central angle is the angle formed when two radii intersect at the center of a circle.

Since chord CB is a diameter of the circle, angle B is a right angle and measures 90 degrees. Arc AB is half the circumference of the circle, so its measure is equal to half the circumference times the ratio of the central angle to the total central angle (360 degrees) of the circle.

Let r be the radius of the circle. Then the circumference is 2 * π * r and the measure of arc AB is:

Arc AB = (1/2) * 2 * π * r * (angle B / 360)

Arc AB = (π * r * angle B) / 180

Arc AB = (π * r * 38) / 180

Answers

10) Using the equation 98.4 = (12.3)8, it costs $12.30 (cost per unit) per uniform.

11) Using the equation 26.70 = k6, the cost of one bag of apples (unit rate) is $4.45.

The unit rate is the quotient of the total cost divided by the number of items contained.

The unit rate is the same as the average or mean of a data set.

We describe the unit rate as the slope of a linear equation.

The unit rate shows the constant rate of change in an equation.

The total cost of 8 uniforms = 98.4 = (12.3)8

The cost per uniform = 12.30 (98.4/8)
