Solve 2x+y=5 2x-3y=1 using substitution method​

Answer»

Step-by-step EXPLANATION:

ANSWER

3x+2y=1 ------- (1)

2x−3y=5 ------ (2)

From EQUATION 1:

2y=13x

2y=1−3x

Y=

1−3x

SUBSTITUTE the value of y in equation 2:

2x−3y=5

Michael has 3 3/8 cups of cereal . A serving of cereal is 3/4 cup. how many servings of cereal does michael haveplease do not spam

Answer»

Given,

TOTAL cups of CEREAL = 3⅜ cups

A serving = ¾ cup

To find,

Total number of possible servings.

Solution,

We can easily solve this MATHEMATICAL problem by using the following mathematical process.

Total cups of cereal = 3⅜ = 27/8 cups

Total servings = Total cups/Needed for one serving = 27/8 ÷ 3/4 = 27/8 × 4/3 = 4.5

(So, 4.5 servings can be made by using the total amount of AVAILABLE cereal on the first hand.)

Hence, 4.5 servings are possible by the present amount of cereal.

Here the concept of QUADRATIC Equations has been used. According to this, the value of variable in the equation has two values. These values are the coordinates of the points of intersection of x - axis. Using thos concept, let's do it !!

_____________________________________________

★ Question :-

Determine the quadratic equation given the sun of the roots -3 and product of the roots 7.

_____________________________________________

★ Solution :-

Given,

» Sum of the roots = -3

» Product of the roots = 7

• Let the required quadratic equation be

ax² + bx + c = 0

Here coefficient of x² = a, x = b and c is the constant term.

So its roots will be α and β.

We know that,

\: \: \large{\boxed{\rm{\leadsto \: \: \alpha \: + \beta \: = \: \dfrac{(-b)}{a}}}}

⇝α+β=

a

(−b)

\: \: \large{\boxed{\rm{\leadsto \: \: \alpha \: \times \: \beta \: = \: \dfrac{c}{a}}}}

⇝α×β=

a

c

Then, according to the question, :-

~ Case I :-

⌬ α + β = -3

\: \: \large{\rm{\longmapsto \: \: \dfrac{(-b)}{a} \: = \: \dfrac{(-3)}{1}}}⟼

a

(−b)

=

1

(−3)

On comparing, LHS and RHS, we get,

⌬ (-b) = (-3) and (a) = 1

Then,

\: \: \large{\boxed{\boxed{\BF{a \: = \: 1 \: , \: b \: = \: 3}}}}

a=1,b=3

~ Case II :-

⌬ αβ = 7

\: \: \large{\rm{\longmapsto \: \: \dfrac{c}{a} \: = \: \dfrac{7}{1}}}⟼

a

c

=

1

7

On comparing, LHS and RHS, we get,

⌬ c = 7 and a = 1

\: \: \large{\boxed{\boxed{\bf{c \: = \: 7}}}}

c=7

So,

⌬ a = 1

⌬ b = 3

⌬ c = 7

Now by applying these values, in the quadratic equation we get,

⌬ x² + 3x + 7 = 0

So the correct option is Option B.) x² + 3x + 7 = 0

\: \: \overbrace{\underbrace{\boxed{\sf{Hence, \: the \: required \: quadratic \: equation \: is \: \bf{x^{2} \: + \: 3x \: + \: 7 \: = \: 0}}}}}

Hence,therequiredquadraticequationisx

⟹Confused?Don

sverifyit:−

For verification, we can simply APPLY the values we got into the Equation and CHECK is linearity.

We know, that when we apply the value of roots, the sum should come to be 0. Then,

=> ax² + bx + c = 0

=> x² + 3x + 7 = 0

Let the value of x be k, then

=> k² + 3k + 7 = 0

Here the linearity satisfies, since we get the same value after applying the K (constant). So our answer is correct.

Hence, Verified.

• Quadratic Equations are the equations which has highest degree of variable to 2 and gives two solutions of the equations. It intersects the graph at x - axis twice.

• Different types of Polynomials are :-

Linear Polynomial - Gives single solution and intersects x - axis just once. Example : Linear Equations

Quadratic Polynomial - Gives two solutions.

Cubic Polynomial - Gives three solutions and intersects x - axis thrice.

Bi - Quadratic Polynomial - Gives four solutions and intersects x - axis four time

FXERCISE2. Find rational numbers between 3 and 4mark an brainlist please​

Answer»

Answer:

Rational number is any number that can express in the form of QP of two integers, where 'Q' cannot be zero.

i) First rational number between 3 and 4 can be calculated by finding average between them, which is  

    23+4=27

Now, we have three numbers i.e. 3,27 and 4, so other remaining rational numbers can be calculated by taking average between 3 and 27, and between 27  and 4.

ii) Second rational number between 3 and 27 can be calculated by finding average between them.

227+3=227+6=413

iii) The third rational number between 4 and 27 can be calculated by finding the average between them.

227+4=227+8=415

iv) Similarly FOURTH rational number between 3 and 413 can be calculated by finding the average between them.
