Beatriz is reading a book tgat has 530 pages. If she reads 10 pages a day, how many days will it take her to finish the book?

2 answers:

6 0

The equation you want to use is this:

10x = 530 10 pages for x days

x = 530/10 530 pages divided by 10 pages

So the answer is,

53 days

If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)

user100 [1]

Answer:

$h(x)=12x-9$

Step-by-step explanation:

We are given the two functions:

$f(x)=4x-2\text{ and } g(x)=-8x+7$

And we want to find:

$h(x)=f(x)-g(x)$

So, by substitution:

$h(x)=(4x-2)-(-8x+7)$

Simplify. Distribute:

$h(x)=(4x-2)+(8x-7)$

Rearrange:

$h(x)=(4x+8x)+(-2-7)$

Combine like terms. Hence:

$h(x)=12x-9$

The answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be

4 $x^{6} y^{-2}$

Step-by-step explanation:

To simplify

$\frac{4(2x^3 y^4 )^4}{2(2x^2 y^6 )^3}$ .

Using exponential law the exponents of variables will be added when multiplied as per rule

we get

$\frac{4[(2^4)(x^{3\times 4}) ( y^{4\times4} )] }{2[(2^3)(x^{2\times3} ) (y^{6\times3} )]}\\$

$\frac{4[(16)(x^{12}) ( y^{16} )] }{2[(8)(x^{6} ) (y^{18} )]}\\\\\frac{64x^{12}y^{16} }{16 x^{6}y^{18} }$

Now by dividing according to exponential rule the exponents of variables will be subtracted as per rule

$(\frac{64}{16} ) x^{12-6} y^{16-18} \\4 x^{6} y^{-2}$

So the answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be

4 $x^{6} y^{-2}$
