Answer:

2f+9

Step-by-step explanation:

First identify the expression for anything such as "less than" or "more than". If there is the whole expression will be flipped.

(Example)

A expression has a "less than" in it.

4f-3

This will turn to 3-4f

_____________________________

Since this has a "More than", whatever you get as your expression will be flipped.

So, the "more" is addition. "Multiplied" is multiplication. So, the expression will be

9+2f

But because of "more than, it will be

2f+9

Picture is shown above<br>suppose that y varies directly with x, and y=12 when x=15

a_sh-v [17]

Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.

Create an exponential to describe $100 at 2% interest compounded annually for x years

zysi [14]

Answer:

$A=100(1.02)^{x}$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=x\ years\\ P=\$100\\ r=2\%=2/100=0.02\\n=1$

substitute in the formula above

$A=100(1+\frac{0.02}{1})^{1*x}$

$A=100(1.02)^{x}$

Kaley reads 6 graphic nwels fewer than Safara.

Misha Larkins [42]

Answer: 16

Step-by-step explanation:

We first find out the number of graphic novels that Kaley reads, we set the number as k.

3k = 30

k = 10

Then Kaley reads 6 graphic novels fewer than Safara, which means that we plus 6 to the number of graphic novels that Kaley read,

k + 6 = 10 + 6 =16
