Step-by-step explanation:

f(x) = 2x + 1. Let y = f(x).

Then y = 2x + 1, 2x = y - 1, x = (y - 1)/2.

If h(x) is the inverse of f(x), then h(x) = (x - 1)/2 = 0.5x - 0.5.

ken has 16 marbles. He wants to put them into bags that hold 5 marbles each. Can there be equal shares of marbles with no marble

LiRa [457]

There can not be equal sharings since 16/5 does not equal a whole number! Good luck :)

Could anyone help me with this whole question? The bottom drop-down question options are, does or does not

Answer:Values for the coefficient in the product k:

$a=b=c=d=3*10^8$ , so the first four boxes should be filled with the number "3"

Drop down arrow: "does"

Step-by-step explanation:

We perform all the products of wavelength time frequency indicated for the column of the quantity "k":

$a$ = $1 * 10^{-10} * 3\, * 10^{18} = 3 * 10^{-10+18} = 3 * 10^{8}$ =

$b=1 * 10^{-1}*3*10^9=3* 10^{-1+9}=3*10^8$

$c=600*10^{-6}*5*10^{11}=3000*10^{-6+11}=3000*10^5=3*10^3*10^5=\\=3*10^{3+5}=3*10^8$

$d=4*10^{-7}*7.5*10^{14}=30.0*10^{-7+14}=30*10^7=3*10*10^7=\\=3*10^{1+7}=3*10^8$

Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : $3*10^8$ , which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.

This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is $3*10^8$ .

$x=\frac{A}{y} \\x*y=A$

Mick can drive his car 33 miles with one gallon of gas. how much gas does he need to drive 15,000 miles (his annual mileage)?

Troyanec [42]

Answer: (pt 1) 454.5 gallons. (pt 2) $1,390.77

Step-by-step explanation:

PART ONE:

$\frac{33}{1} = \frac{15,000}{x}$

33 · x = 15,000 · 1

33x = 15,000

x = $\frac{15,000}{33}$

x = 454.5 (rounded)

PART TWO:

454.5 · 3.06 = 1,390.77
