Step-by-step EXPLANATION:

(x + 1/ x ) ² = 3 ( 1+ 1 / x ) + 4

x² + 2 + 1 / x² = 3 + 3 / x + 4

x² + 2 + 1 / x² = 7 + 3 / x

x² + 1 / x² + 2 − 7 − 3 / x = 0

This is not QUADRATIC equation.

Step-by-step explanation:

zero of polynomial means the VALUE of X which is yeilding the polynomial as 0

2x²+9x-5

by mid term splitting 2x²+10x-x -5 =0

                                 2x(x+5) -1(x+5) =0

                                  ( 2x-1)(x+5)=0

Answer:

Step-by-step explanation:

5(3y+4)=-2(2-6y)

We simplify the equation to the form, which is simple to UNDERSTAND

5(3y+4)=-2(2-6y)

Reorder the terms in PARENTHESES

+(+15y+20)=-2*(2-6y)

Remove unnecessary parentheses

+15y+20=-2+*(+2-6y+)

Reorder the terms in parentheses

+15y+20=+(-4+12y)

Remove unnecessary parentheses

+15y+20=-4+12y

We move all terms containing y to the left and all other terms to the right.

+15y-12y=-4-20

We simplify left and right side of the equation.

+3y=-24

We DIVIDE both SIDES of the equation by 3 to GET y.

y=-8

Step-by-step EXPLANATION:

As it's given the class can be divided into groups of 2,3,5 and 6.

So we have to find LCM(LEAST Common FACTOR) of 2,3,5 and6 .

LCM of 2,3,5 and 6=

|2,3,5,6

2|1, 3,5,3

3|1, 1,5, 1

5|1, 1, 1, 1

So the common factors are 2,3 and 5.

Hence, the least NUMBER of children the class can have = 2×3×5=30.

Answer:

Let’s assume that we have to find solution for a1x + b1y + c1 = 0 (i) and a2x + B2Y + c2 = 0 (ii)

Step 1: Multiply Equation (i) by b2 and Equation (ii) by b1, to get

b2a1x + b2b1y + b2c1 = 0 ---(iii)

b1a2x + b1b2 y + b1c2 = 0 ----(IV)

Step 2: Subtracting Equation (4) from (3), we get:

(b2a1 – b1a2) X + (b2b1 – b1b2) y + (b2c1– b1c2) = 0

Or (b2a1 – b1a2) x + (b2c1– b1c2) = 0

Or x = (b1c2– b2c1)/ (a1b2 – a2b1)

Step 3: Substituting this value of x in (i) or (ii), we get

y = (c1a2 – c2a1)/ (a1b2 – a2b1)

Step 4: Calculate value of a1b2 – a2b1

Step 5: if a1b2 – a2b1 ≠ 0 or a1/a2 ≠ b1/b2, then equation has definite solution.

Step 6: if a1b2 –a2b1 =0 or a1/a2 = b1/b2, then there are two possibilities

When a1/a2 = b1/b2 = c1/c2 , then there are infinitely MANY solutions.

When a1/a2 = b1/b2 ≠ c1/c2, then there is no solution.

ANSWER:

Step-by-step EXPLANATION:

SECQ + TANQ)(1-sinQ) = COSQ

LHS = (1/cosQ +sinQ/cosQ)(1-sinQ)

=( 1+sinQ/cosQ)(1-sinQ)

= 1-sin^2Q/cosQ

=cos^2Q/cosQ

= cosQ

Answer:

Step-by-step explanation:

F1(t) is the cubic function;

F2(t) is the exponential function;

F3(t) is the quadratic function.

Here are some observations which lead to these conclusions.

All POWER functions ktp with p  0 are zero for t = 0. Thus F2 cannot be a power function.

Assuming that F1(t) = ktn with n = 2 or n = 3, we can evaluate F1(1) to obtain k. In this case, k = 2.5.

Since F1(t) = (2.5)tn with n = 2 or n = 3, we can FIGURE out n by evaluating at t = 1.2.

(2.5)(1.2)2 = 3.6 and (2.5)(1.2)3 = 4.32,

so n = 3.
