The problem is stated incorrectly.  It should be 7 DAYS and NOT years.

ending amount = beginning amount * (1.8)^days
7 years = 2,555 days
ending amount = 30 * 1.8^7
ending amount = 30 * <span> <span> <span> 61.2220032 </span> </span> </span>
ending amount = <span> <span> <span> 1836.660096 </span> </span> </span> or 1,837 (rounded)
answer is D.

Dovator [93]
From the graph, we can say that the system can be represented by a linear function. A linear function has a standard form of:

y = mx + b where m is the slope and b is the y-intercept.

From the image, b would have a value of 48. The slope can be calculated as follows:

slope = ( 48 - 36 ) / (0 - 1) = -12

The equation can be written as:

y = -12x +48
or
12x + y = 48

Will mark brainliest !

Answer:

x = 9

y = 6

Step-by-step explanation:

  1. Divide 15 by 2: 15 ÷ 2 = 7.5
  2. Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
  3. Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
  4. Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)

3) 2x² + 7x - 30<br><br> AC method
Vinvika [58]

Hello

a=2, b=7, c= -30

ac=-60

-60= 12*(-5)

We can see that 12*(-5)=ac and 12-5=b=7

So

2x^2+7x-30=2x&2+12x-5x-30=2x(x+6)-5(x+6)=(x+6)(2x-5)

Thanks
