Answer:

[tex]y = -\frac{2}{5}x -\frac{1}{5}[/tex]

Step-by-step explanation:

Given

Passes through: [tex](2,-1)[/tex]

Parallel to: [tex]2x + 5y = 15[/tex]

Required

First, calculate the slope of the parallel line

[tex]2x + 5y = 15[/tex]

Make y the subject

[tex]5y = 15 - 2x[/tex]

Divide through by 5

[tex]y = 3 - \frac{2}{5}x[/tex]

[tex]y =- \frac{2}{5}x+3[/tex]

An equation in slope intercept has the form:

[tex]y = mx + b[/tex]

Where:

m = slope

[tex]y = mx + b[/tex]

So:

[tex]m = -\frac{2}{5}[/tex]

The required is parallel to [tex]2x + 5y = 15[/tex].

This mean, the same slope

The equation is the calculated using:

[tex]y - y_1 = m(x - x_2)[/tex]

This gives:

[tex]y - (-1) = -\frac{2}{5}(x - 2)[/tex]

[tex]y +1 = -\frac{2}{5}x +\frac{2}{5}*2[/tex]

[tex]y +1 = -\frac{2}{5}x +\frac{4}{5}[/tex]

[tex]y = -\frac{2}{5}x +\frac{4}{5}-1[/tex]

Take LCM

[tex]y = -\frac{2}{5}x +\frac{4-5}{5}[/tex]

[tex]y = -\frac{2}{5}x -\frac{1}{5}[/tex]

i.e.

[tex]y = -2/3x -1/5[/tex]

Answer:

Polly used 15 bags to fill this sack of rice.

Step-by-step explanation:

Each kilogram has 1000 grams.

Polly has a full 5 kg sack of rice. Each full bag contains 350 g of rice. How many bags did Polly fill from this sack of rice?

We solve this by rule of three, using proportions.

Each bag has 350g of rice. In all, x bags will have 5kg = 5*1000 = 5000g of rice. So

1 bag - 350g

x bags - 5000g

Applying cross multiplication

[tex]350x = 5000[/tex]

[tex]x = \frac{5000}{350}[/tex]

[tex]x = 14.3[/tex]

Since a decimal part of a bag is not possible, Polly used 15 bags to fill this sack of rice. 14 complete, and the last bag the remaining part.

Answer:

3x2+15x=18

Step 1: Subtract 18 from both sides.

3x2+15x−18=18−18

3x2+15x−18=0

Step 2: Factor left side of equation.

3(x−1)(x+6)=0

Step 3: Set factors equal to 0.

x−1=0 or x+6=0

x=1 or x=−6

I worked them out myself so if their wrong uh please don't get mad I tried my best.

Step-by-step explanation:

3x (2) + 15x = 18                               3x (2) + 15x = 18

6x + 15x = 18                                     6x + 15x = 18  

-6x + -6x = 18                                            -18     -18

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

0 + 9x = 18                                            6x + -3 = 0

   ------  -------                                         -3 +  -3

      18  18                                           --------------------

          x = 2                                              -3 + 0

                                                                    X = -3

Given:

The table for a linear function.

To find:

The equation of the linear function.

Solution:

If a linear function passes through two points, then the equation of linear function is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the given table. Let the two points are (2,-2) and (4,0). So, the equation of linear function is

[tex]y-(-2)=\dfrac{0-(-2)}{4-2}(x-2)[/tex]

[tex]y+2=\dfrac{2}{2}(x-2)[/tex]

[tex]y+2=x-2[/tex]

Subtracting 2 from both sides.

[tex]y+2-2=x-2-2[/tex]

[tex]y=x-4[/tex]

So, Ethan 's made a mistake. The sign between x and 4 must be negative but in Ethan's equation it is a positive sign, which is not correct.

Therefore, the required linear equation is [tex]y=x-4[/tex].

Answer:

The package weighs 21.6 pounds

Step-by-step explanation:

$4 dollars + T(0.60 tax per pound) divided by 15.40( the full cost of the shipment)

15.40 divided by 0.60 = 25.6

25.6 - 4 = 21.6

Answer:

a² + 4a + 4

Step-by-step explanation:

= a ( a + 2) + 2 ( a + 2)

= a² + 2a + 2a + 4

= a² + 4a + 4

Answer:

Yes,

There is a direct proportional relationship between the cost of items before tax and the cost of items after tax.

Step-by-step explanation:

Given - A city has a 5% sales tax.

To find - Is there a proportional relationship between the cost of items

              before tax and the cost of items after tax?  

Proof -

Yes, cost of items before tax is directly proportional to cost of items after tax.

Reason -

With the increase in the sales tax, there is increase in the cost of items after tax, therefore, there is a direct relation between cost of items before tax and cost of items after tax.

Answer:

they lost 144 yards -144

Step-by-step explanation:

The person has lost 144 yards.

An arithmetic intelligence operation minus simulates the process of deleting items from either a collection. To subtract is to take something or something from a particular group. The group's total number of items decreases and became lower when people eliminate it. The components of a subtraction issue are the issues dealing with, forces at play, and differences.

The information that is given:

The football squad of the Saddleback Seahawks acquired 37 yards inside the opening period of the game,

dropped 88 yards in the second period,

recovered 105 yards throughout the third period,

Regained 12 yards in the fourth.

Total that is gained is = 37 + 12 = 49

Total that is lost = 88 + 105

Total amount of yard changes = 49 + 193

= -144 yards.

Answer:

16

every time you go up 10% there will be 2 added

2*8=16

Step-by-step explanation:

If 10% of a number is 2 less than 20% of the same number, then 80% of the number equals 16.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

10% of a number is 2 less than 20% of the same number,

10% .x=20%x-2

Convert % to the decimal by diving with 100.

10/100x=20/100x-2

0.1x=0.2x-2

Subtract 0.1x on both sides

0=0.2x-0.1x-2

Add 2 on both sides

2=0.2x-0.1x

2=0.1x

Divide both sides by 0.1

20=x

Now we need to find 80% of 20.

80% of 20

80/100×20

0.8×20

16

Hence, 10% of a number is 2 less than 20% of the same number, then 80% of the number equals 16.

Answer:

0.0326 = 3.26% probability that she is a student.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Woman developer

Event B: Student

Probability that the developer is a woman:

7.4% of 25.8%(students).

76.4% of 100 - 25.8 = 74.2%(not students). So

[tex]P(A) = 0.074*0.258 + 0.764*0.742 = 0.58598[/tex]

Student and woman developer.

7.4% of 25.8%(students), so

[tex]P(A \cap B) = 0.074*0.258 = 0.019092[/tex]

If we encounter a woman developer, what is the probability that she is a student

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.019092}{0.58598} = 0.0326[/tex]

0.0326 = 3.26% probability that she is a student.

Answer:

  1856

Step-by-step explanation:

The numbers given do not have a common difference, but they do have a common ratio:

  58/29 = 116/58 = 2

The general term of a geometric sequence with first term a1 and common ratio r is ...

  an = a1×r^(n-1)

For this sequence, a1=29 and r=2, so the general term is ...

  an = 29×2^(n-1)

Then the 7th term is ...

  a7 = 29×2^(7-1) = 29×64 = 1856

The 7th term is 1856.

_____

If you prefer, you can double each term until you have 7 of them.
