Answer:

22

Step-by-step explanation:

Find f(-3) :

f(x) = x² + 2x for x ≤ -3

That means for those values of x, less than or equal to -3, this is the function.

So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3

Now, f(-1) :

From the given data, we see it is: f(x) = 2 [tex](\frac{1}{3} )^{2x}[/tex]

We take this because -1 lies between -3 and 4.

Now, f(-1) = 2 [tex](\frac{1}{3} )^{2(-1)}[/tex]

 => [tex]f = (-1) = 2(3)^{2} = 2 (9) = 18[/tex]

For f(4) :

Clearly, the function is: [tex]f (x) = \frac{2x - 5}{x-7}[/tex]

[tex]f (4) = \frac{2(4)-5}{4-7} = \frac{3}{-3} = -1[/tex]

Therefore, f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.

Answer:

20 adults and 10 children

Step-by-step explanation:

We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.

Answer:

10 children  20 adults

Step-by-step explanation:

children = c

adult = 2c (double than children)

2(c) + 4(2c) = 100

10c = 100

c = 10     10 children

30-10 = 20   20 adults

$2(10) = $20

$4(20) = $80

$20+$80 = $100

Answer:

The longer length is either 99, 33 or 11 inches

Step-by-step explanation:

Given

[tex]Area = 99[/tex]

Required

The length of the longer side

Area of a rectangle is:

[tex]Area = Length * Width[/tex]

List out all possible products that give 99 [Assume the dimension are whole numbers]

[tex]Length * Width = 99 * 1 = 99[/tex]

[tex]Length * Width = 33 * 3 = 99[/tex]

[tex]Length * Width = 11 * 9 = 99[/tex]

List out the longer factors

[tex]L = \{99, 33, 11\}[/tex]

Hence, the longer length is either 99, 33 or 11 inches

Step-by-step explanation:    TS 5 15 8 26

L = W + 4

Area = 45 ft²

Area = LW

Area = (W +4)(W) = 45 ft²

         W² + 4W - 45 = 0        solve for W

         (W + 9)(W - 5) = 0

         W = -9 or 5                a minus 9 width makes no sense

     L = W + 4

     L = 5 + 4

W = 5 ft   L = 9 ft

Answer:

  B. (3/2x, 3/2y)

Step-by-step explanation:

It is perhaps easiest to see that B' is 3 grid squares from the origin while B is 2 grid squares from the origin. The scale factor is the ratio of these distances:

  3/2

Dilation about the origin multiplies each coordinate value by the scale factor:

  (x, y) ⇒ (3/2x, 3/2y)

Answer:

answer is given in up paper. where ans is -1/2

350 dollars

(step 1) Find the cost per kilogramme of sugar in shop X

In shop X:

250 grams of sugar costs 150 dollars.

Remember that;

1000 grams = 1 kilogramme.

=> 250 grams will be equal to 0.25 kilogramme

Therefore (replacing 250 grams with 0.25 kilogramme) in shop X;

0.25 kilogramme of sugar costs 150 dollars

Now, if

0.25 kilogramme = 150 dollars,

=> 1 kilogramme =  150 dollars x 1 kilogramme / 0.25 kilogramme

=> 1 kilogramme = 600 dollars

Therefore, the cost per kilogramme of sugar in shop X is 600 dollars

(step 2) Find the cost per kilogramme of sugar in shop Y

In shop Y:

100 grams of sugar costs 95 dollars.

Remember that;

1000 grams = 1 kilogramme.

=> 100 grams will be equal to 0.1 kilogramme

Therefore (replacing 100 grams with 0.1 kilogramme) in shop Y;

0.1 kilogramme of sugar costs 95 dollars

Now, if

0.1 kilogramme = 95 dollars,

=> 1 kilogramme =  95 dollars x 1 kilogramme / 0.1 kilogramme

=> 1 kilogramme = 950 dollars

Therefore, the cost per kilogramme of sugar in shop Y is 950 dollars

(step 3) Find the difference in cost per kilogramme of sugar between the two shops

The difference is calculated by subtracting the cost per kilogramme of sugar in shop X from the cost per kilogramme of sugar in shop Y. i.e

=> cost per kilogramme of sugar in shop Y - cost per kilogramme of sugar in shop X

=> 950 dollars - 600 dollars

=> 350 dollars.

Therefore, the difference in cost per kilogramme is 350 dollars

Answer:

  (c)  (10, 2)

Step-by-step explanation:

Adding the two equations, we have ...

  (d +e) +(-d +e) = (12) +(-8)

  2e = 4

  e = 2 . . . . . . matches choice C

  (d, e) = (10, 2)

Answer:

Step-by-step explanation:

Given that:

To Label:

Adding equation (i) and (ii).

⟶ d + e + (- d + e) = 12 + (- 8)

⟶ d + e + - d + e = 12 - 8

Cancelling d.

⟶ 2e = 4

⟶ 2e = 2 × 2

Cancelling 2.

⟶ e = 2

In equation (i)

⟶ d + e = 12

Putting the value of e.

⟶ d + 2 = 12

⟶ d = 12 - 2

⟶ d = 10

Hence,

Answer:

Result :

3 • (2x + 1) • (x + 1) • (3x + 5)

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

STEP1

Equation at the end of step 1

(6x + 3) • ((3x2 + 8x) + 5)

STEP2

STEP3

Pulling out like terms

3.1 Pull out like factors :

6x + 3 = 3 • (2x + 1)

Trying to factor by splitting the middle term

3.2 Factoring 3x2 + 8x + 5

The first term is, 3x2 its coefficient is 3 .

The middle term is, +8x its coefficient is 8 .

The last term, "the constant", is +5

Step-1 : Multiply the coefficient of the first term by the constant 3 • 5 = 15

Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .

-15 + -1 = -16

-5 + -3 = -8

-3 + -5 = -8

-1 + -15 = -16

1 + 15 = 16

3 + 5 = 8 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5

3x2 + 3x + 5x + 5

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (x+1)

Add up the last 2 terms, pulling out common factors :

5 • (x+1)

Step-5 : Add up the four terms of step 4 :

(3x+5) • (x+1)

Which is the desired factorization

Answer:

   Mathematics   :Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.

Since the beginning of recorded history, mathematic discovery has been at the forefront of every civilized society, and in use in even the most primitive of cultures. The needs of math arose based on the wants of society. The more complex a society, the more complex the mathematical needs. Primitive tribes needed little more than the ability to count, but also relied on math to calculate the position of the sun and the physics of hunting.

Answer:

A.) uses a related sample (repeated measures).

B.) does not use a related sample.

Step-by-step explanation:

The first scenario uses a related sample whereby same subjects were used to over the course of each related experiment (comparing if people eat more or less when in a hurry). After the completion of both experiment, we'll have two different reading for each subject which a b further be used to compare the difference in consumption when in a hurry and when not.

The second scenario here fails to employ a related sample design as the the subjects used have contrasting characteristics, a group consisting of lonely people and another consisting of those who aren't lonely.

Answer:

  54 = 2 × 3³

  36 = 2² × 3²

Step-by-step explanation:

The term "factors" can mean different things in this context. Usually, it means "prime factors." Exponents are used to indicate the number of times a factor is repeated. The prime factors of these numbers are ...

  54 = 2 × 3³

  36 = 2² × 3²

__

Sometimes, we use the word "factors" to mean "positive integer divisors." The number of divisors is the product of the exponents of the prime factors, each increased by 1. That is, 54 has (2·4) = 8 divisors; 36 has (3·3) = 9 divisors. The odd number of divisors is one indication that the number is a perfect square.

The divisors of these numbers are ...

  54 is divisible by 1, 2, 3, 6, 9, 18, 27, 54

  36 is divisible by 1, 2, 3, 4, 6, 9, 12, 18, 36

Step-by-step explanation:

Given

[tex](2x)(x^2) + (2x)(x) + (2x)(-2) + (3)(x^2) + (3)(x) + (3)(-2)[/tex]

Required

The simplified product

We have:

[tex](2x)(x^2) + (2x)(x) + (2x)(-2) + (3)(x^2) + (3)(x) + (3)(-2)[/tex]

Open bracket

[tex](2x)(x^2) + (2x)(x) + (2x)(-2) + (3)(x^2) + (3)(x) + (3)(-2) = 2x^3 + 2x^2 -4x + 3x^2 + 3x -6[/tex]

Collect like terms

[tex](2x)(x^2) + (2x)(x) + (2x)(-2) + (3)(x^2) + (3)(x) + (3)(-2) = 2x^3 + 2x^2+ 3x^2 -4x + 3x -6[/tex][tex](2x)(x^2) + (2x)(x) + (2x)(-2) + (3)(x^2) + (3)(x) + (3)(-2) = 2x^3 + 5x^2 -x -6[/tex]

Hence, the simplified product is: [tex]2x^3 + 5x^2 -x -6[/tex]
