y<−3/2x−2

y>−3/2x−2

y≤−3/2x−2

Answer:

[tex]19^{z-y}[/tex]

Step-by-step explanation:

assuming you meant z > y

using the rule of exponents

[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{m-n}[/tex] ( m > n ) , then

[tex]\frac{19^{z} }{19^{y} }[/tex] = [tex]19^{z-y}[/tex]

According to the solving the line segment LM of line KM = 3.

A line segment is defined as the area between two different points on a line. A line segment is a section of a line that links two points. A line has no endpoints and stretches in both directions indefinitely, but a line segment includes two fixed or definite endpoints.

In general, if both end points of a line segment are vertices of such a polygon or polyhedron, the line segment has to be either the edge (of that polygon or polyhedron) if they are both adjacent vertices, or a diagonal. A chord is a line segment whose end points are both on a curve (such as a circle) (of that curve).

KL = 9

LM = x - 1

KM = -4 + 4x

So

KL + LM = KM

Substituting the value we get:

9 + x - 1 =  -4 + 4x

8 + x = -4 + 4x

8 + 4 = 4x - x

12 = 3x

x = 4

The value of x  = 4 putting the value in the (LM = x - 1):

We get:

LM = x - 1

LM = 4 - 1

     = 3

LM = 3

According to the solving the line segment LM of line KM = 3.

The number of video games that Max will have left when he keeps one is 18 games.

It should be noted that the total amount that he has is $625.95.

Cost of each video game = $32.10

Therefore, the number of games that he can buy will be:

= Amount / Cost of game

= $625.95 / $32.10

= 19.5

= He can buy 19 games.

Therefore, if he keeps one, the number left will be:

Population in the year 2000= 198.85million

From the question, we get to know that the population in 2009 was 191.5 million.

And we have to find the population of the year 2000 which is 3.7%more than the 2009 population.

So let us take the population of the year 2000 to be x.

From the above, we can form an equation:

(population of year 2000 * ( 100-3.7 /100) = (population of year 2009)

i.e., x * 100-3.7/ 100 = 191.5

x * 96.3 = 191.5

x = 198.85

So 198.85 is the population of 2000.

Step-by-step explanation:

It is clear that the number of sweets that should be bought so that each child can get either 8 or 9 sweets should be divisible by both 8 and 9

This is called the LCM or least common multiple of 8 and 9
Since 8 and 9 have no divisors in common LCM of 8 and 9 is 72 so 72 is the minimum number of sweets to buy so that there are no leftovers if each child gets 8 or 9 sweets

Let's compute the number of sweets that were bought the first time. Let the number of children be X

Since each child got 8 sweets and 2 were left over, the total of sweets must be 8X + 2

If each child were to get 9 sweets each then there would be 2 sweets short

This can be written as 9X -2 for the total number of sweets

Since these have to be equal,
9X - 2 = 8X + 2

Add 2 to both sides:
9X - 2 + 2 = 8X +2 + 2
9X = 8X + 4

Subtract 8X from both sides
9X - 8X = 8X - 8X + 4
1X = 4
==> X = 4
So number of children is 4

Total number of sweets bought
= 8 x 4 + 2 = 34

or

= 9 x 4 - 2 = 34

Therefore number of extra sweets to be bought = 72 - 34 = 38

The interest that 2560 earns in 17 months at a rate of 5 1/8% is $185.9.

In the fields of finance and economics, interest is the payment of a sum over and above the principal amount to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. It is not the same as a fee that the borrower might pay to the lender or another entity.

Principal = $2560

Time = 17 months = 1.417 years

Rate = 5.125%

Therefore, the Interest will be:

= (Principal × Rate × Time) / 100

= (2560 × 1.417 × 5.125) / 100

= $185.9

Therefore, its area would be:

[tex]A = (x + 6)^2 \text{ // Remember: } (a + b)^2 = a^2 + 2ab + b^2\\\to A = x^2 + 12x + 36[/tex]

the zeroes of the function f (x) = 2 x² + 8 x - 3 are x = - 2 ± √ 11 / 2.

We are given a function:

f (x) = 2 x² + 8 x - 3

We need to use the completing the square method to find the zeroes.

f (x) = 2 x² + 8 x - 3

f (x) =  x² + 4 x - 3 / 2

f (x) =  ( x )² + 2 (2) (x) + (2)² - (2)² - 3 / 2

f (x) = ( x + 2 )² - 4 - 3 / 2

f (x) = ( x + 2 )² - 11 / 2

(x + 2)² = 11 / 2

x + 2 = ± √ 11 / 2

x = - 2 ± √ 11 / 2

Therefore, the zeroes of the function f (x) = 2 x² + 8 x - 3 are x = - 2 ± √ 11 / 2.

The simplest form of the expression is determined by solving the fractional exponent.

If an exponent of the base (number) is expressed in a fraction, it is called a fractional exponent. In an expression say x^1/y, 1/y is the fractional exponent. Fractional exponent represents the power and root together.

In the given expression, the base term is -32y^15, while the exponent is 1/5.

Since, (ab)^m=a^mb^m

Hence, (-32y¹⁵)^¹/₅=(-32)^1/5*(y^15)^1/5

When a base number has a negative sign, and the power is an odd number, the negative sign is extracted.

(-32)^1/5*(y^15)^1/5=-(32)^1/5*(y^15)^1/5

Since, (a^m)^n=a^m*n

-(32)^1/5*(y^15)^1/5=-32^1/5y^15*1/5

As 32=2*2*2*2*2=2^5

The expression becomes.

-(2^5)^1/5*(y^15^)1/5

Multiplying the powers,

-(25)^1/5*(y^15)^1/5=-(2^5*1/5)(y^15*1/5)=-2y^3

The simplest form of expression is (-32y¹⁵)^¹/₅ is -2y^3.
