Answer:
51.5 in , Formula: y=1/2x+48
Step-by-step explanation:
First, create a formula as shown above
Next, plug your number into the formula:
y=1/2(7)+48
Then, simplify your equation by multiplying 1/2 by 7 and getting 3.5, now add 48 and you get 51.5in
Last, check your work by adding 1/2 seven times and you will get the same result
I hope this helps you and if it does please give a thanks (i would eternally appreciate a brainliest trying t level up)

Answer: x ≥ 11
Step-by-step explanation: We wrote an inequality to represent this situation.
First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms
anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.
Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.
The axis of symmetry is 6
