Answer:
2(125x^3 - 4)
Step-by-step explanation:
..........
2x - 5 = 7
2x = 7 + 5
2x = 12
2x/2 = 12/2
x = 6
to check:
2x - 5 = 7
2(6) - 5 = 7
12 - 5 = 7
7 = 7
Answer:
36
Step-by-step explanation:
So, you would need to multiply 75 and 48 then divide by 100 then your final answer is 36.
Answer:
The second one, question 4, would be C, y = -2x + 16
Step-by-step explanation:
You're trying to make an equation out of the information on the graph.
So, start with the format y = mx + b.
The variable m represents the slope. Use rise/run. I chose to use the points (0, 16) and (2, 12).
You would end up with a rise over run that looks like this: 4/2. Simplified, the slope would be 2. Because this line is moving downwards, your slope is negative.
So far, you have y = -2x + b.
The variable b represents the initial value, or where the line first touches the y-axis. You can see that the initial value is 16.
Plug that in. y = -2x + 16.
Hope this helps! Sorry I couldn't answer both, good luck on that test! <3
