Diego bought some raisins and walnuts to make trail mix. Raisins cost $4 a pound and
walnuts cost $8 a pound. Diego bought a total
of 2 pounds of raisins and walnuts combined.
He spent a total of $15 on both ingredients. How
many pounds of each pounds of each
ingredient did he buy?
Explain or show how you arrived at your answer.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
