Answer:

In this case, the unknown numbers have been assigned with corresponding variables which are ww and vv.

The key is to recognize that we are going to subtract the product by the quotient of some expressions.

the product of 77 and ww is expressed as 7w7w

the quotient of 22 and vv is expressed as \Large{{2 \over v}}

Therefore, the difference of the product and quotient is 7w - {\Large{{2 \over v}}}7w−

Step-by-step explanation:

Example 4: The difference of the product of 77 and ww, and the quotient of 22 and vv.

Minimum point of the quadratic x^2+6x-2

WITCHER [35]

Answer:

(-3,-11)

Step-by-step explanation:

Compare the given quadratic equation with the general quadratic equation.

a=1, b=6 and c=-2

$x=-\dfrac{(6)}{2(1)}\\=-3$

Subsitute $-3$ for $x$ in given quadratic equation.

$y=(-3)^2+6(-3)-2\\=9-18-2\\=-11$

The minimum point is (-3,-11).

Apply the properties of exponents to verify that each statement is an identit.

Sholpan [36]

Answer and explanation :

We have given that the expression $\frac{2^{n+1}}{3^n}=2\times (\frac{2}{3})^n$

We have to prove L.H.S = R.H.S

Lets take L.H.S

$\frac{2^{n+1}}{3^n}$

It can be written as $\frac{2^{n+1}}{3^n}=\frac{2^n\times 2^1}{3^n}$ ( As in multiplication exponent are added )

So $\frac{2^n\times 2^1}{3^n}=(\frac{2}{3})^n\times 2$ = R.H.S

Hence proved

Tim is 4 years older than one-third of Juan's age. In 10 years, Juan will be 6 years older than twice as old as Tim is now. How

olga55 [171]

Answer:

Juan's current age = 12

Tim's current age = 8

Step-by-step explanation:

Let x= Juan's current age; x+10=Juan's age in 10 years

Then (1/3)x+4=Tim's current age;

Now we are told that:

x+10=2{(1/3)x+4}+6 eliminate brackets

x+10=(2/3)x+8+6 =(2/3)x+14 multiply both sides by 3

3x+30=2x+42 subtract 30 and 2x from both side s

3x-2x+30-30=2x-2x+42-30 collect like terms

Juan's current age: x=12

Tim's current age: (1/3)x+4=(1/3)*12+4=8

4 years older than 1/3 of Juan's age=(1/3)*12+4=8

8=8

In 10 years, Juan will be 6 years older than twice as old as Tim is now.

12+10=22

2*8+6=22

22=22
