C) reflection over the x-axis
Answer:
Step-by-step explanation:
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
The standard form: ax^2 + bx + c
I hope this helps!
If you dont get the answers, just let me know ^^
Answer:
The first chart
Step-by-step explanation:
when its set up as y = [5x] is 5 times x equals y, so going through each question, -2 x 5 = -10, -1 x 5 = -5, 0 x 5 = 0, 1 x 5 = 5, and 2 x 5 = 10
The answer is B (-8,6) this is because the magnitude is 2 so each tiny square is going to increase or decrease by intervals of 2 so if you count by two to the left you get 8 but since its going to the left that will be -8x and now you need to count up by 2's and that equals to 6y and you are at A on the graph so the answer will be (-8,6)
Answer:
The difference between twice a number and a number that is 5 more than 3. Write an equation that could be used to find the value of the number n,
