Answer:
33
Step-by-step explanation:
1. (x-10)+67=90 because it's a 90 degree angle
2.subtract 67: x-10=23
3. add 10: x=33
I leaerned this neat trick
you don't need to convert to vertex form
where
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by inserting the x value of the vertex into the equation
so
1x^2-6x+14
-b/2a=-(-6)/2(1)=6/2=3
plug that in
y=x^2-6x+14
y=3^2-6(3)+14
y=9-18+14
y=5
the vertex is (3,5)
Answer:
None of them?!? -3 is bigger than -10, and -13 is less than -10.
This doesn't make sense, unless it's only talking about what's on the right, witch would make 1 or 3... This is very weird.
