Solve the following compound inequality -24 ≤2x-10 ​

Considering the definition of parallel and perpendicular line, you get:

A linear equation o line can be expressed in the form y = mx + b

where

Parallel lines are two lines that are always at the same distance from each other.

Two lines are parallel if they have the same slope and different y-intercepts.

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

The line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.

If you multiply the slopes of two perpendicular lines, you get –1, the slope perpendicular line can be calculated as:

5/8× slope perpendicular line= -1

slope perpendicular line= (-1)÷ 5/8

slope perpendicular line= -8/5

So, the perpendicular line has a form of: y= -8/5x + b

The line passes through the point (8, 4). Replacing in the expression for perpendicular line:

4= -8/5×8 + b

4= -64/5 + b

4 + 64/5= b

84/5= b

Finally, the equation of perpendicular line is y= -8/5x + 84/5.

In this case, the line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.

If two lines are parallel if they have the same slope, the parallel line has a slope of 5/8 and has a form of: y= 5/8x + b

The line passes through the point (8, 4). Replacing in the expression for parallel line:

4= 5/8×8 + b

4= 5 + b

4 -5 = b

-1 = b

Finally, the equation of parallel line is y= 5/8x - 1

By looking at the points, we can see that point E' is a reflection over the x-axis of the point E. That, since the y-component changed it's sign.

Answer:

17

Step-by-step explanation:

To find k, we use

∫∞−∞∫∞−∞fXY(x,y)dxdy=1.

Thus, we have

1=∫∞−∞∫∞−∞fXY(x,y)dxdy=∫10∫10x+cy2dxdy=∫10[12x2+cy2x]x=1x=0dy=∫1012+cy2dy=[12y+13cy3]y=1y=0=12+13c.

Therefore, we obtain c=32.

To find P(0≤X≤12,0≤Y≤12), we can write

P((X,Y)∈A)=∬AfXY(x,y)dxdy,for A={(x,y)|0≤x,y≤1}.

Thus,

P(0≤X≤12,0≤Y≤12)=∫120∫120(x+32y2)dxdy=∫120[12x2+32y2x]120dy=∫120(18+34y2)dy=332.

We can find marginal PDFs of X and Y from their joint PDF. This is exactly analogous to what we saw in the discrete case. In particular, by integrating over all y's, we obtain fX(x). We have

Marginal PDFs

fX(x)=∫∞−∞fXY(x,y)dy, for all x,fY(y)=∫∞−∞fXY(x,y)dx, for all y.

Example

In Example 5.15 find the marginal PDFs fX(x) and fY(y).

The other endpoint of the segment is (7, 14)

From the question, we have:

On the segment, we have the following endpoints

Endpoint 1, A = (-3,-2)

Midpoint, M = (2,6)

The midpoint of the segment is calculated using

Midpoint (x, y) = 1/2 * (x1 + x2, y1 + y2)

Where

(x1, y1) = (-3,-2)

(x, y) = (2,6)

Substitute the known values in the above equation

So, we have

(2, 6) = 1/2 * (-3 + x, -2 + y)

Multiply both sides of the equation by 2

So, we have

(4, 12) = (-3 + x, -2 + y)

By comparison, we have

-3 + x = 4

-2 + y = 12

Evaluate the like terms in the above equation

So, we have

x = 7

y = 14

When the above solution is represented as a coordinate, we have the following

(x, y) = (7, 14)

Hence, the other endpoint of the segment where the segment has the endpoint (-3,-2) and midpoint (2,6) is (7, 14)

Where:

(xA , yA) , (xB , yB)  given

to find ,  (xC , yC)

(xA , yA) = (2,0) , (xB , yB) = (5,7)  and yC = 7

to find xC ,

xC - xA = (yC - yA) / (yB - yA) . (xB - xA)

xC =  xA + (yC - yA) / (yB - yA) . (xB - xA)

xC = 2 + (7-0)/(7-0) x (5 - 2)

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.

Given Data

Jay needs 19 quarts more paint for the outside of his barn than for the inside.

he uses 107 quarts in all

Paint needed for Inside = x

Paint needed for outside =  x + 19

So,

Answer

When x = 12, y = 180

Explanation

We are told that y varies directly as x, which can be written as

y ∝ x

Introducing the constant of variation, k, we have

y ∝ x

y = kx

We can then solve for k knowing that

y = 90 when x = 6

y = kx

90 = (k) (6)

90 = 6k

Divide both sides by 6

(90/6) = (6k/6)

15 = k

k = 15

We can then write the relationship between y and x as

y = kx

y = 15x

when x = 12, y = ?

y = 15x

y = 15 (12) = 180

The value of the limit will be equal to -2.

A function may be defined as the one in which for one input variable x there is only one output variable y.

The given statement can be written as an algebraic expression as: 2/(x + 2).

A mathematical statement that expresses phrases or words using numbers, variables, and operation signs can be referred to as an algebraic expression.

To translates a given statement in to algebraic expression, we can use "x" as a variable to represent the unknown number in the given word problem.

For example, the number that is added to 2, in the above given scenario, can be represented as "x" in order to translate the given statement into an algebraic expression.

The word "sum" will be represented with the operation sign, "+". Therefore, "the sum of 2 and a number" will be translated as an algebraic expression as, (x + 2).

Therefore, the whole statement, "2 divided by the sum of 2 and a number" will then be expressed in algebraic expression as: 2/(x + 2).

Explanation:

Consecutive even integers are things like 2,4,6,8 or 20,22,24,26

Each number is even and the numbers follow one after another.

Let x be the first even number. The next even number is x+2

Based on the fact that "five times the first equals four times the second", we can then write the equation of 5x = 4(x+2)

Let's solve for x.

5x = 4(x+2)

5x = 4x+8

5x-4x = 8

x = 8 is the first even number

x+2 = 8+2 = 10 is the second even number

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

Check:

5*(first) = 4*(second)

5*8 = 4*10

40 = 40

The answers work out.

Two consecutive even integers such that five times the first equals four times the second are 8 and 10.

Let us suppose the first integer as  a,

Then the second consecutive even integer would be a+2

from the question, it is evitable that,

5a = 4(a+2)

5a = 4a + 8

a = 8

Therefore first even integer is 8.

The second even integer will be,

a+2

8+2 = 10

Cross verifying:

5 × 8 = 40

4 × 10 = 40

Hence the two consecutive even integers such that five times the first equals four times the second are 8 and 10.
