Ok hold on... for 13, do 1000/1 times 2/3 then simplify. U know how to do that? If not I'll tell u wen I'm done with 14 because, sadly I'm only a 7th grader and all I know is 13 and 14. For 14, do 4/1 times 5/2 then simplify.

Which function is the inverse of f(x) = -5x-4?

tankabanditka [31]

Step-by-step explanation:

$f(x) = - 5x - 4$

$\:$

<u>Inverse</u>

$y = - 5x - 4$

$x = - 5y - 4$

$x + 4 = - 5y$

$y = - \frac{(x + 4)}{5}$

${f}^{ - 1} (x) = - \frac{(x + 4)}{5}$

Mohamed decided to track the number of leaves on the tree in his back yard each year. This year there were 500 leaves. Each year

makkiz [27]

Answer:

Geometric sequence

Step-by-step explanation:

According to the scenario, computation of the given data are as follows:

Leaves on tree this year (a) = 500

Rate of increase in leaves per year (r) = 40 % or 0.4

Let n be the number of years.

So we use exponential growth formula, i.e.

f(n) = a(1+r)^n

by putting the value, we get

f(n) = 500 ( 1+0.4)^n

or f(n) = 500 (1.4)^n

So, the common ration is 1.4.

Thus, it shows a geometric sequence.

You spin the spinner and flip a coin. Find the probability of the compound event.

Mademuasel [1]

Answer:

The probability of spinning an even number and flipping heads is 1/4

Step-by-step explanation:

You spin the spinner and flip a coin.

A spinner that has 1 of each number, 1-6

Total events =12

(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)

(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)

We are supposed to find probability of spinning an even number and flipping heads

Favorable events : (2,H),(4,H)(6,H) = 3

Total events = 12

The probability of spinning an even number and flipping heads = $\frac{3}{12}=\frac{1}{4}$

Hence The probability of spinning an even number and flipping heads is 1/4
