Answer:

0y^2 + 2z^3 + 3y^3

Step-by-step explanation:

The simplified form of the expression is 0y²+2z³ + 3y³

The given expression is -1/3y² + 2/3 z³ +1/3y² +3y³+4/3z³.

In the expression y, z are the variables.

Combine the like terms:

(-1/3+1/3)y²+(2/3+4/3)z³ + 3y³

Simplify each term:

0y²+2z³ + 3y³

Hence, the simplified form of the expression is 0y²+2z³ + 3y³

The given sequence is arithmetic because it is increases gradually by 5

so the answer is "an arithmetic" and "difference" is equal to "5"

Answer:

[tex]\sf \dfrac{x+2}{x}[/tex]

Step-by-step explanation:

Simplifying the expression:

 1. Factorize each expression.

     x² + 8x + 15

   Sum = 8

  Product = 15

  Factors = 3 , 5  {When we add 3 & 5 we get 8 and when we multiply 3*5, we get 15}

  x² + 8x + 15 = x² + 3x + 5x + 15

                     = x(x + 3) + 5(x + 3)

                     = (x + 3)(x + 5)

x² - 2x - 15

 Sum = -2

Product = -15

Factors = 3 , (-5)  {When we add 3 + (-5) =2 and when we multiply, 3*(-5) = -15}

x² - 2x - 15 = x²  + 3x - 5x - 15

                 =x(x + 3) -5(x + 3)

                 = (x + 3)(x - 5)

x² + 5x = x( x + 5)

x² - 3x - 10

Sum = -3

Product = -10

Factors = 2 , (-5)  {When we add 2 +(-5) = -3 and when we multiply 2 *(-5) = -10}

x² - 3x - 10 = x² + 2x - 5x - 10

                 =x(x + 2) - 5(x + 2)

                 = (x + 2)(x - 5)

2. Use KCF method and simplify.

  K - keep the first fraction

  C - change division to multiplication

 F -  Flip the second fraction.

[tex]\sf \dfrac{x^2 + 8x + 15}{x^2 - 2x - 15} \ \div \ \dfrac{x^2 + 5x}{x^2 - 3x - 10}=\dfrac{x^2 + 8x + 15}{x^2-2x - 12}*\dfrac{x^2 - 3x - 10}{x^2 + 5x}[/tex]

                                              [tex]\sf = \dfrac{(x +3)*(x +5)}{(x+3)(x - 5)}*\dfrac{(x + 2)(x - 5)}{x(x+5)} \\\\= \dfrac{x + 2}{x}[/tex]

Answer: b and d

Step-by-step explanation:

Angle x of the triangle PQR is 53 degrees.

Angle x is gotten by alternate angle relationship.

Line AB is parallel to line CD

Therefore,

AB║CD

Hence,

62 + x = 115(alternate angles)

62 - 62 + x = 115 - 62

x = 53°

Answer:

x = 50

Step-by-step explanation:

Angle <BPR and angle <PRD are supplementary angles so their sum is equal to 180

m<BPR + 115 = 180 subtract 115 from both sides

m<BPR = 65

angles:

<APQ, x, and <BPR form a straight line and so their sum is equal to 180

65 + x + 65 = 180 add like terms

130 + x = 180 subtract 130 from both sides

x = 50

The store bought the phone for $140 and sells the cell phone for $315 at a markup of 125%.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the markup, since the store sells the cell phone for $315, hence:

(315 - 140)/140 * 100% = x

x = 125%

(If my answer was helpful, please mark as Brainliest. I'm trying to get to the Expert rank!)

You have the correct answer. Apply a 180 degree rotation around the point (0,2)

Reason:

We'll connect corners between figures A and B.

Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).

Draw another line from the lower right corner to the upper left corner. This line is in blue.

The red and blue lines intersect at the center of rotation (0,2)

The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.

Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.

Using translation concepts, the graph of g(x) is given as follows:

It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent and translated functions are given, respectively, by:

The transformations are as follows:

f(x) has vertex at (0,0), hence g(x) will have the vertex at (5,1). When x = 2, g(x) = (2-5)^2 + 1 = 10, hence the correct statement is:

It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).

The distance between points M and N according to the task content is; 9.8 meters.

From observation of the task content information; it can be deduced for a fact that the line segment MN which joins points M and N is parallel to the line JK. This follows from the fact that M and N are midpoints of KL and JL respectively.

Hence, it follows that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality;

NM/19.6 = 7.4/(2×7.4)

NM = 19.6/2 = 9.8 meters.

This follows from congruence theorems in which case, the ratio of corresponding sides of congruent triangles are equal.

The equation of the line containing (- 4,5) and perpendicular to the line 5x - 3y = 4 is y = -3 / 5 x + 13 / 5

The equation of a line can be represented as follows:

y = mx + b

where

Therefore, the equation passes through (-4, 5) and perpendicular to 5x - 3y = 4

Hence,

perpendicular lines follows the rule below:

m₁m₂ = -1

Hence,

5x - 3y = 4

5x - 4 = 3y

y = 5/ 3 x - 4 / 3

m₁ = 5 / 3

5/3 m₂ = -1

m₂ = - 3 / 5

Hence,

using (-4, 5)

5 = - 3 / 5 (-4) + b

5 = 12 / 5 + b

b = 5 - 12 / 5 = 25 - 12 /5 = 13 / 5

Answer:

  3x +5y = 13

Step-by-step explanation:

The equation of a perpendicular line through a given point can be obtained by swapping the x- and y-coefficients of the original line's equation, and negating one of them. The constant in the equation needs to be chosen so the equation will be true at the given point.

Swapping the coefficients of the given equation, we have ...

  3x -5y = c . . . . . for some constant c

Negating the y-coefficient gives a perpendicular line:

  3x +5y = c

We want the equation to be true for (x, y) = (-4, 5), so the constant needs to be ...

  3x +5y = 3(-4) +5(5) = -12 +25 = 13

The equation of the perpendicular line is ...

  3x +5y = 13

Additional comment

This process works for equations given in any form. If you start with point-slope form or slope-intercept form, some manipulation of the result may be required to get to the form you want. Standard-form or general-form equations are the easiest to apply this method to.

Note that equations in standard form want to have a positive leading coefficient. That is why we chose to change the sign of the y-coefficient, rather than the x-coefficient.

Answer: x > -1, see attached.

Step-by-step explanation:

To solve the inequality, we will isolate the x-variable.

Given:

Add 19 to both sides:

    3x > -3

Divide both sides by 3:

    x > -1

To graph, we will use an open circle since it is only greater than and not equal to. Then, we will place this circle on -1. Lastly, we will shade to the right of -1, since it is greater than -1.

Answer:

8

Step-by-step explanation:

The equation of the parabola can be represented as

[tex]y = a(x + 1)(x - 5)[/tex]

for some constant a.

Since the coefficient of x² is 2, a = 2, so

[tex]y = 2(x + 1)(x - 5) \\ \\ y = 2( {x}^{2} - 4x + 5) \\ \\ y = 2 {x}^{2} - 8x + 10[/tex]

So, the answer is 8.

Answer: The correct answer is choice A.

Step-by-step explanation:

This is because the triangles have the same angles, but are scaled differently.  Thus because of the scale, there can be no correlation between the sides. Because the triangles share point E you can see that both triangles share the same angle but also notice how lines CD and AB are parallel. This makes all angles identical proving the triangles are the same but different sizes. Concluding that choice A is correct.

Observe that

so that

[tex]P(x+2) = (x+2)^2 - (x+2) - 1 \implies P(x) = x^2 - x - 1[/tex]

Then

[tex]P(x - 1) = (x-1)^2 - (x-1) - 1 \\\\ ~~~~~~~~ = (x^2 - 2x + 1) - (x - 1) - 1 \\\\ ~~~~~~~~ = \boxed{x^2 - 3x + 1}[/tex]

Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height
