solve for x 2(3x-2)-4x+1=9 linear equations with disbribution

Answer:The answer is y = 2x3 + 4x2 – x + 5 and  y = –3x2 + 4x + 9

Roots are both: x=-4, x= -1/2 , x= 1

Proof:

Solve for x over the real numbers:

2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9

Subtract -3 x^2 + 4 x + 9 from both sides:

2 x^3 + 7 x^2 - 5 x - 4 = 0

The left hand side factors into a product with three terms:

(x - 1) (x + 4) (2 x + 1) = 0

Split into three equations:

x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0

Add 1 to both sides:

x = 1 or x + 4 = 0 or 2 x + 1 = 0

Subtract 4 from both sides:

x = 1 or x = -4 or 2 x + 1 = 0

Subtract 1 from both sides:

x = 1 or x = -4 or 2 x = -1

Divide both sides by 2:

Answer:  x = 1 or x = -4 or x = -1/2

Step-by-step explanation:

The answer is y = 2x3 + 4x2 – x + 5 and  y = –3x2 + 4x + 9

Roots are both: x=-4, x= -1/2 , x= 1

Explanation:

Solve for x over the real numbers:

2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9

Subtract -3 x^2 + 4 x + 9 from both sides:

2 x^3 + 7 x^2 - 5 x - 4 = 0

The left hand side factors into a product with three terms:

(x - 1) (x + 4) (2 x + 1) = 0

Split into three equations:

x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0

Add 1 to both sides:

x = 1 or x + 4 = 0 or 2 x + 1 = 0

Subtract 4 from both sides:

x = 1 or x = -4 or 2 x + 1 = 0

Subtract 1 from both sides:

x = 1 or x = -4 or 2 x = -1

Divide both sides by 2:

Answer:  x = 1 or x = -4 or x = -1/2

Answer:

closed circle on 6 and shaded to the left

Step-by-step explanation:

22. l = 12m

b = 10m

Perimeter = 2(l + b)

= 2(12 + 10)

= 24 + 20

= 44m

Area = l×b

= 12 × 10

= 120m²

(a) Fencing required = 44m

Cost per metre = $12

Cost for the fencing of 44m = 12 × 44

= $528

(b) Levelling required = 120m²

Cost per metre² = $50

Cost for the levelling of 120m² = 120 × 50

= $6000

Step-by-step explanation

percentage just means "out of 100"

Answer:

x = 2

Step-by-step explanation:

This works because the two equations are set equal to each other, making them share a common value between them.

You can also plug both of these equations into a graphing calculator, and on the graph select the command to calculate the intersection.

Hope this helped!

Answer:

x = 2

Step-by-step explanation:

Given the 2 equations

2x - y = 6 → (1)

5x + 10y = - 10 → (2)

Multiplying (1) by 10 and adding to (2) eliminates the y- term.

20x - 10y = 60 → (3)

Add (2) and (3) term by term to eliminate y, that is

25x = 50 ( divide both sides by 25 )

x = 2

The value of x at the point of intersection is x = 2

▹ Answer

$16.50

▹ Step-by-Step Explanation

If you are trying to find the new price, we will deduct 25% from the original cost of $22.

To figure this out, you can multiply 0.25 * 22.

From there, you will get $5.50. This means there will be a $5.50 discount applied. To find the new cost, we will now subtract.

$22 - $5.50 = $16.50

The new cost of the skateboard is $16.50.

Hope this helps!

y = 50

angle AOB = 100

=========================================

Explanation:

Angle x is an inscribed angle that subtends or cuts off minor arc AB. This is the shortest distance from A to B along the circle's edge.

Angle y is also an inscribed angle that cuts off the same minor arc AB. Therefore, it is the same measure as angle x. We can drag point D anywhere you want, and angle y will still be an inscribed angle and still be the same measure as x.

-------------------

Point O is the center of the circle. This is because "circle O" is named by its center point.

Angle AOB is considered a central angle as its vertex point is the center of the circle.

Because AOB cuts off minor arc AB, and it's a central angle, it must be twice that of the inscribed angle that cuts off the same arc.

This is the inscribed angle theorem.

Using this theorem, we can say the following

central angle = 2*(inscribed angle)

angle AOB = 2*(angle x)

angle AOB = 2*50

angle AOB = 100 degrees

Answer:

x = 14

Step-by-step explanation:

7x - 27 = 3x + 29

Subtract 3x from both sides;

4x - 27 = 29

Add 27 to both sides;

4x = 56

Divide both sides by 4;

x = 14

Answer/Step-by-step explanation:

1. YES.

Converse: If same side interior angles are supplementary, then l || m. (Same side interior angles)

Since the sum of the two same side interior angles, 65° and 115°, equals 180°, therefore, l || m.

2. YES.

Converse: if two angles angles are a linear pair, they are supplementary, therefore l || m. (Linear pair)

Thus,

128° + 53° = 180°.

3. YES.

Converse: if two angles are corresponding angles and congruent, therefore l || m. (Corresponding angles).

Thus,

The indicated angles which are equal to 90°, are corresponding angles therefore, l || m.

4. YES

Converse: if two alternate exterior angles are congruent, then l || m. (Alternate exterior angles)

Thus, the two exterior angles are congruent, therefore l || m.

The converse which would serve as prove that l is parallel to m are given in the answers below:

Considering the information in the given diagrams:

1. Yes, l is parallel to m.

The converse is: "If corresponding angles are equal, then  l is parallel to m".  One of the corresponding angles plus [tex]115^{o}[/tex] equals [tex]180^{o}[/tex].

Thus, l || m.

2. Yes, l is parallel to m.

The converse is: "if two angles are linear pair, then they sum up to [tex]180^{o}[/tex]".

So then, l || m.

3. Yes, l is parallel to m.

The converse is: "if two corresponding angles are right angles, then they are congruent".

Therefore, l || m.

4. Yes, l is parallel to m.

The converse is: :if two alternate exterior angles are congruent, then l is parallel to m".

Therefore, l || m.

Answer: Php 107.55

Step-by-step explanation:

From the question, Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday . The Total amount saved will be:

= 4.50 + 7.25 + 5.55 + 3.95 + 8.15

= 29.40

Amount saved for 3 weeks will be:

= 29.40 × 3

= 88.20

Since the lunch box he wants to buy costs Php 195.75 and he has saved Php 88.20. The remaining amount will be:

= 195.75 - 88.20

= 107.55

Answer:

5km

Step-by-step explanation:

The distance between two coordinates is expressed as;

D = √(x2-x1)²+(y2-y1)²

Marker 1 is at coordinate (2,1) and marker 2 at (-3,1)

Substitute into the formula

D = √(-3-2)²+(1-1)²

D = √(-5)²

D = √25

D = 5

Hence the distance between marker one and two is 5km

Answer:

7330 sq.ft

Step-by-step explanation:

Area covered by the beam = Area of sector

Area of sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex]

Where,

[tex] \theta = 84° [/tex]

Radius (r) = 100 ft

Plug in the values into the formula

Area of sector = [tex] \frac{84}{360} \times \pi 100^2 [/tex]

Area of sector = [tex] \frac{84 \times \pi \times 10,000}{360} [/tex]

Area of sector = 7,330 ft² (nearest square foot)
