are there instances that rational algebraic equation can be transformed into quadratic equation​

Answers

Answer:

yeah

Step-by-step explanation:

hmm

Answer:

yes you can

Step-by-step explanation:

for example you have a second order algebraic equation, which have the general form ax^2 + bx + c = 0, for any constants a, b, and c, you can use the quadratic equation to find the values of x. However, sometimes it is easier to simply factor the expression into (fx+g)(hx+i) = 0, for any constants f, g, h, and i, and then solve the two resulting equations fx+g = 0 and hx+i=0 for the values of x.

Nesther Omar nor Daisy likes to be outside in the rain.​

Answers

Answer:

Step-by-step explanation:

1. Omar got a new puppy "and" named her Daisy.

P (compound predicate)

The compound predicates are 'got' and 'named'

The word 'and' combined the predicates

2. Daisy "and" Omar enjoy playing outside together in good weather.

S (compound subject)

The compound subjects are 'Daisy' and 'Omar'

The word 'and' combined the subjects

3. "Neither" Omar "nor" Daisy likes to be outside in the rain.

S (compound subject)

The compound subjects are 'Omar' and 'Daisy'

The words 'neither nor' combined the subjects

1. un numar se mareste cu 4 iar rezultatul se mareste de 4 ori. noul rezultat micsorat cu 4 se imparte la 4 si se obtine 4.aflati numarul

Answers

Răspuns:

1

Explicație pas cu pas:

Fie numărul = x

x + 4 = e - - (1)

e * 4 = f - - - (2)

Ecuația 2 - 4 împărțită la 4 = 4

(f - 4) / 4 = 4

Crucea se înmulțește

f - 4 = 16

f = 16 + 4

f = 20

Rezultatul 1 împărțit la 4 este egal cu 4

Prin urmare,

e = f / 4

f = 20

e = 20/4

e = 5

De la (1)

x + 4 = e

x + 4 = 5

x = 5 - 4

x = 1

If on a scale drawing 75 feet are represented by 45 inches, then a scale of 1/5 represents how many feet

Answers

Answer:

1/3 feet

Step-by-step explanation:

We are given that

On a scale drawing

45 inches represented =75 feet

We have to find a scale of 1/5 inch how many feet represents.

To find the value in feet represented by  a scale of 1/5 inch we will use unitary method.

Using unitary method

45 inches represents =75 feet

1 inch represents = feet

1/5 inch represents = feet

1/5 inch represents= feet

Hence, a scale of 1/5 inch represents 1/3 feet

B. Trisha is shorter than 25% of girls aged 16 to 18.
C. Trisha is shorter than 75% of girls aged 16 to 18.
D. Trisha is taller than 75% of girls aged 16 to 18.
What is the answer

Answers

Answer:

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.

Step-by-step explanation:

When a dataset is divided into four equal parts, the first part is called the lower quartile. The data is usually sorted in ascending order before finding quartiles.

The lower quartile contains 25% of the whole data. The values in lower quartile are are less than 75% of the values.

If Trisha's height is in lower quartile that means her height is less than the girls in middle and higher quartile.

Hence,

The correct answer is:

C. Trisha is shorter than 75% of girls aged 16 to 18.

Answer:

Money Laura had originally = $30

Money spent = 2/5 of x = [tex]\frac{2}{5}x[/tex]

Remaining money  = $ 18

[tex]x - \frac{2}{5}x = 18\\\\\frac{x*5}{1*5}-\frac{2}{5}x = 18\\\\\frac{5x}{5} - \frac{2x}{5} = 18\\\\\frac{3x}{5}=18\\\\ 3x = 18*5\\\\3x = 90\\\\x = \frac{90}{3}\\\\x = 30[/tex]

Help please

Answers

Answer:

The answer is 32 & 27 because they add up to 59 and 27 is 5 less than 32.

Step-by-step explanation:

Answer:

32, 27

Step-by-step explanation:

Call one number (the larger one)  "x"

The other number (smaller one) is " x - 5"

As per the given information;

x + x - 5 = 59

Inverse operations;

x + x - 5 = 59

        +5    +5

2x = 64

/2    /2

x = 32

Larger number= 32

Smaller numbers = x - 5 = 32 - 5 = 27
