What is the equation for the axis of symmetry for this quadratic function
2 answers:
Answer: x = -2
Step-by-step explanation: That axis of symmetry is the
fold line or the line that splits the parabola down the middle.
The line that makes this parabola symmetrical is x = -2.
So our axis of symmetry is x = -2.
An easy way to find it is average the zeros (x-intercepts) and multiply by 1/2.
So here, -4 + 0 is -4 and -4(1/2) is -2.
Answer:
The answer to your question is x = -2
Step-by-step explanation:
Process
Identify the kind of curve. This is a vertical parabola that opens upwards.
The axis of symmetry is the line that divides the parabola into two identical sections.
This line must be a vertical line that passes through the Vertex.
The Vertex is the lowest point of the parabola. Vertex = (-2, -4).
Then, the axis of symmetry must be x = -2

There are NO SOLUTIONS.
Substitute the first equation for y in the second equation. You can see it does not work. 6 does not equal 8. Therefore there are no solutions.
So the ratio to longboard to short board is 1:4, the total of that ratio is 5. 35 ÷ 5 = 7. now we're going to take those ratios and multiply 1 × 7 = 7 and 4 × 7 = 28. Your final answer is B. to confirm your answer add 28 + 7.
The answer should be 24, because you can mark out 5,and 10 cuz it doesn’t make since
