Ellen is playing a video game in which she captures butterflies. there are 3 butterflies onscreen, but the number of butterflies doubles every minute. after 4 minutes, she was able to capture 7 butterflies.

a. look for a pattern write an expression for the number of butterflies after 4 minutes. use the power of 2 in your answer

b. write an expression for the number of butterflies remaining after ellen captured the 7 butterflies. simplify the expression

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b
