If the axis of symmetry is x=-1, the vertex will have x-coordinate -1.
The point (0, 5) cannot be the vertex. The friend is not correct.
_____
If the point (1, 5) is on the graph so is the image of that point when it is reflected across the axis of symmetry. That image point is (-3, 5). A parabola that goes through points (1, 5) and (-3, 5) will not go through point (0, 5).
Answer:
7 = 2y
Step-by-step explanation:
No problem ;)
There is two 1/8's to make 1/4. This is proven by the following example:
1/8 + 1/8 = 2/8.
2/8 (simplified) = 1/4.
Given the information above, we can safely figure out this problem.
Since 2/8 make 1/4, and we're looking for 3/4, multiply 2/8 by 3.
2/8 x 3 = 6/8.
It will require 6 total 1/8's.
I hope this helps!
Ok so you already have the formula so basically plug in the numbers (6,7,8,9) into the equation till you find the one that makes a true statement.
2*6+2(2*6+3)= 42
do the same for the rest and you will find that 9 is the width
2*9+2(2*9+3)=60
