2x + 2y = −8 3x − 2y = 33

Mathematics
1 answer:
Mariulka [41]3 years ago
4 0

Step-by-step explanation:

2x+2y= -8

3x-2y= 33

first cancel out +2y&-2y

  • then chose 1 equation...let's take the first one and then 2x= -8
  • divided both sides by 2:x= -4
  • then substitute the value of x in the second equation:3(-4)-2y=33
  • -12-2y=33
  • 2y=33+12
  • 2y=45
  • divide both sides by 2: y=22.5

The table represents an exponential function.
Mama L [17]

Answer:

Step-by-step explanation:

All we are doing here is solving for the b in

y=a(b)^x, which is the standard form for an exponential function.

Use the first 2 coordinate pairs to solve for b: (1, 6) and (2, 4):

6=a(b)^1 so

a=\frac{6}{b} and use that when you write the next equation using the next coordinate pair:

4=\frac{6}{b}(b)^2 which simplifies to

4 = 6b so

b=\frac{2}{3}, the second choice there. Another way of saying multiplicative rate is the rate of decay or the rate of growth. Same thing. This is decay since 2/3 is greater than 0 but less than 1.
