Mathematics

Answer:

Both would work.

Step-by-step explanation:

If we call Jackie's apples a, then Mark has a - 4 apples. Therefore, together they have a + (a - 4) apples, and we know that they have a total of 12 apples so we can write a + (a - 4) = 12 to represent the situation. On the other hand, if Mark has a apples, then Jackie has a + 4 apples, so we can also write a + (a + 4) = 12 to represent the situation as well. Therefore, both of the equations would work. Hope this helps!

-3x - 3y = 3 <br> y= -5x - 17
Kruka [31]

you first plug (substitute) in y

-3x - 3(-5x-17)=3

then distribute

-3x+15x+51=3

now combine like terms

12x+51=3

subtract to get 12x by itself

12x=3-51 or 12x=-48

lastly divide by 12 to find x

12x/12=-48/12

x=-4

now find y by plugging x into the other equation

y=-5(-4)-17

y=3

(-4,3)

The population of a local species of beetle can be found using an infinite geometric series where a1 = 880 and the common ratio
nasty-shy [4]
<span>Data:

infinite geometric series

A1 = 880

r = 1 / 4

The sum of a geometric series  in sigma notation is:

  n              1 - r^n
 ∑ Ai = A ----------- ; where A = A1
i = 1             1-r

 When | r | < 1 the infinite sum exists and is equal to</span><span><span>:

  ∞               A
 ∑ Ai =   ---------- ; where A = A1
i = 1          1 - r</span>

So, in this case</span><span><span>:

  ∞               880
 ∑ Ai =    -------------- = 4 * 880 / 3 = 3520 /3 = 1173 + 1/3
i = 1         1 - (1/4)</span>  </span>

Answer: 1173 and 1/3
