Answer:
20. Which of the following is the correct first step to solve 5x2 – 20x = -15 by completing the square?
O Divide all terms by 5. this is the answer
O Divide all terms by -5.
Add 15 to both sides.
Add 100 to both sides.

Answer:
choices A, B, and D are all true
choice C is false
Step-by-step explanation:
Choice A is true because both functions shown on the graph have exactly one asymptote at about y=1.
Choice B is true because well, the reason Choice C is not true. logarithmic graphs and exponential graphs look very similar. However, exponential graphs get very close to the x-axis but never actually touch it. In this graphing, the blue function crosses the x-axis, so it cannot be an exponential function. The only other function that has graphs that look like this is a logarithmic function, so Choice B is correct and Choice C is not correct.
Once again, Choice C is not correct because the blue graph crosses the x-axis and exponential functions never actually touch the x-axis no matter how close they get to it.
Choice D is correct because the red graph has been reflected over the x-axis and shifted upward, and the blue graph has been reflected across the y-axis and shifted to the right.
Answer:
6x^2 + 4x
Step-by-step explanation:
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
Answer:
8a+13b
Step-by-step explanation:
First start by multiplying the coefficient with the parantheses.
3(2a+3b)+2(a+2b)
6a+9b+2a+4b
8a+13b
This equation cannot be further simplified.
4 because if you add 4 and 8 that would be 12
