Can somebody help me

Mathematics
1 answer:
patriot [66]3 years ago
4 0

Answer:

Down below

Step-by-step explanation:

1. 3/4x-7-16, combine -7 and -16, 3/4x-23

2. -8+2y+4, combine -8 and 4, 2y+4

3. -4x+11x+3y, combine -4x and 11x, 7x+3y

4. 41+b-25b, combine b and -25b, 41-24b

5. -1/2(8x-2), distribute: -1/2*8x and -1/2*-2, -4x+1

6. $40, 15% off: 40(1.00-0.15)= $34

So simplifying expressions means to just combine like terms (e.g. 2 and 4, 5x and -18x, 7y and y, etc.)

Distribution means to apply the multiplication to the terms inside the parentheses (e.g. a(x+y) -> ax+ay)

Sales is just: original price * (1 - percent off by)

I hope this helps!

Graph both functions to find the solution(s) to the system. Use the line tool to graph the line.
kumpel [21]
The graph shows solutions to be ...
  (x, f(x)) = (x, g(x)) = (-2, 5), (2, -3)

_____
Analytically, it works well to find
  g(x) -f(x) = 0
  (x^2 -2x -3) -(-2x +1) = 0
  x^2 -4 = 0
  x^2 = 4
  x = ±√4 = ±2
Then
  f(-2) = -2(-2) +1 = 5
  f(2) = -2(2) +1 = -3

Consider that an = 4n-1 represents a sequence. What is the tenth term? A) 361 B) 512 C) 1,024 D) 4,096 E) 262,144
mel-nik [20]

Hello from MrBillDoesMath!

Answer:

Choice E.

Discussion:

Assuming that n >=1, a(n) = 4n -1, then

a(10) = 4(10) - 1 = 39    

but that doesn't match any of the answers...... hmm...

BUT

If you meant that a(n) = 4^(n-1),  then

a(10) = 4^(10-1) = 4^9 =  262144    

which is Choice E.

Thank you,

MrB
