Answer:

Step-by-step explanation:

hello :

4x2 - 6x - 4 =0 means : (x - 2)(4x + 2)=0

x-2=0 or 4x+2=0

x=2 or x=-1/12 no 12

Step-by-step explanation:

Number 1

$log_{10}( {x}^{2} - 3x + 12 ) = 1 \\ log_{10}( {x}^{2} - 3x + 12 ) = log_{10}(10) \\ cancelling \: both \: logs \: we \: have \\ {x}^{2} - 3x + 12 = 10 \\ {x}^{2} - 3x + 12 - 10 = 0 \\ {x}^{2} - 3x + 2 = 0 \\$

$solve \: \: by \: factorisation \: method \\ {x}^{2} - 2x - x + 2 \\ {x}(x - 2) \: - 1(x - 2) \\ (x - 2)(x - 1) \\ therefore \: x = 2 \: or \: x = 1$

F(x)=16^X<br> 1. F(x)=4 x/4<br> 2.f(x)=2^4x<br> 3. F(x)=2 x/4<br> 4. F(x)=4^4x

Answer:

2.f(x)=2^4x

Step-by-step explanation:

16^x

We can rewrite 16 as 2^4

2^4^x

We know that a^b^c is equal to a^ (b*c)

so 2^(4*x)

2^(4x)

Atul has 2/3 lb of candy. Jose has 3/5 lb and Maria has 1/2 lb less then José. How many more pounds of candy does Atul have than

liraira [26]

Given:

Atul has $\dfrac{2}{3}$ lb of candy.

Jose has $\dfrac{3}{5}$ lb of candy.

Maria has $\dfrac{1}{2}$ lb less than Jose.

To find:

How many more pounds of candy does Atul have than Maria?

Solution:

Since, Maria has $\dfrac{1}{2}$ lb less than Jose, therefore

Maria has = $\dfrac{3}{5}-\dfrac{1}{2}$ lb

Maria has = $\dfrac{6-5}{10}$ lb

Maria has = $\dfrac{1}{10}$ lb

Difference between the candies Atul and Maria have.

Difference = $\dfrac{2}{3}-\dfrac{1}{10}$ lb

Difference = $\dfrac{20-3}{30}$ lb

Difference = $\dfrac{17}{30}$ lb

Therefore, Atul have $\dfrac{17}{30}$ lb of candy more than Maria.

IRISSAK [1]

Hi,

To add two fraction, they must have the same denominator.

So 5/6 = 10/12

Now : 10/12 + 1/12 = 11/12
