Answer:
30*d
When you are making your equation it has to work for everything so you use a variable.
Y-4=1/4*(x-1)²
<span>y=1/4(x-1)²+4
</span><span>the parabola y=1/4x2 with vertex at the point (1;4),the branches up,x=1 is the axis of symmetry intersects the axis of the OY at the point (0;4 1/4)
</span>
1. The total of x and 29.
This is because we see addition going on, so x+29 is the total of something
Hope this helps :)
