I will guest that it will be these answers:
The best represent the scenario shown in the graph of the quadratic functions, y = x2 and y = x2 + 3 are the following: -The quadratic function, y = x2, has an x-intercept at the origin   -From x = -2 to x = 0, the average rate of change for both functions is negative  
-For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.

How to solve this <br>3 = (2x + 8)/3​
seropon [69]

Answer:

x = 1/2

Step-by-step explanation:

First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.

9 = 2x + 8

Then, subtract 8 from both sides to get x by itself.

1 = 2x

Finally, divide both sides by 2 so you only have one x

1/2 = x

This means that the answer is x = 1/2.

  • sin θ = opposite/hypotenuse

<u>Opposite:</u>

  • y- coordinate of given point = 21

<u>Hypotenuse:</u>

  • √x²+y² = √20²+21²= √841 = 29

<u>Then</u>
