The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.
-2.7=y then make that equal sign into the normal sign again. -2.7
Answer:
The two triangles are related by A - S - A test of similarity , so the triangles are congruent.
This is a parabola which has vertex at the origin and opens upwards.
general form is x^2 = 4ay where a is the focus
the focus is the same distance from the vertex as the directrix So it is at the point (0, 6)
required equation is x^2 = 4*6 y
or y = (1/24) x^2
Answer:
a) A = {-3, -2, -1}
b) n(A) = 3
c) A is finite
Step-by-step explanation:
a) The elements of A are the integers between -4 and 0, not including those values. Those integers are -3, -2, -1, so those are the elements of set A.
A = {-3, -2, -1}
__
b) n(A) is the number of elements in set A. Obviously, there are 3:
n(A) = 3
__
c) Since n(A) is not "infinity", the set A is finite.
