Answer:
Leah's unit rate is 16 problems per minute.
Step-by-step explanation:
To find her unit rate, we need to find how many problems she can do in 1 minute. Our current fraction is . We need to divide the top and bottom by 2.5 to get the rate per minute
=
Leah's unit rate is 16 problems per minute.
Answer:The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius. hoped it helped :)

Answer:
<h2>
D. Two</h2>
Step-by-step explanation:
Two common points of the graphs (two intersects) means two solutions.
Step-by-step explanation:
Since the focus lies on the x axis, and the diretcrtirx is a vertical line, we have a sideways parabola so we have the equation
where h,k is the vertex and
p is the distance from the vertex to the focus or the distance fromcthe vertex to the directrix.
Since the focus is 1.5, and the directrix is -1.5 the vertex is (0,0) so we have
We know p is 1.5 so we have
91000
when it says nearest ten you ignore the decimals and look at 90998 the nearest ten of 998 is 1000 so keep the nine at the beginning and you have 91000
