Consider the family of curves described by: x^2+ xy + ay^2= b. Remember to justify your answers. A. Let a =1 and b = 7. Find the two x-intercepts.

B. Let a =1 and b = 7. Using the two points you found in part A, show that the tangents to the curve at these points are parallel, and find the common slope.

C. A given curve in the family x^2 + xy + ay^2 = b has a tangent line at point (1, 3) with slope −5/14. What are the values of a and b?

I need help with part a and part b. I don't understand them.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

step-by-step explanation:

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
