⓵
Replace the w with it’s value in the equation :
w⒳ = -2x + 1
-7 = -2x + 1
⓶
Then, you just simplify the right side in order to isolate the x (always take in consideration your priorities of operation) :
-7 = -2x + 1
÷-2 ÷-2
3.5 = x + 1
-1 -1
2.5 = x ☻

I suppose you're supposed to convert 100111 from base 2 to base 10. We have
so the missing number is 39.

Answer:</h3>
f(x) = -(x -2)² +3
<h3>
Step-by-step explanation:</h3>
We can fill in the vertex (h, k) values immediately in the vertex form ...
... f(x) = a(x -h)² +k
To find the value of a, we solve the equation for a at some point other than the vertex. The given point is (0, -1), so we can use that:
... -1 = a(0 -2)² +3
... -4 = 4a . . . . . . . . . subtract 3, simplify
... -1 = a . . . . . . . . . . . divide by 4
Now, we know the function is ...
... f(x) = -(x -2)² +3
