Answer:
y - 3 = 5(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 5 and (a, b) = (- 1, 3), hence
y - 3 = 5(x - (- 1)), that is
y - 3 = 5(x + 1) ← in point- slope form
Answer:
y = 2x^2 +1
Step-by-step explanation:
This is a parabola so it is in the form
y = a( x-h) ^2 + k
where ( h,k) is the vertex which is at ( 0,1)
y = a (x - 0)^2 + 1
y = ax^2 +1
Pick another point on the graph to determine a
(1,3)
3 = a(1)^2 +1
Subtract 1 from each side
3-1 = a(1)
2 =a
y = 2x^2 +1
I think you definitely need technology and objects to represent the data
Hello from MrBillDoesMath!
Answer:
The imaginary part = 2i.
Discussion:
Generally, a complex number is written as "a + bi", where a and b are understood to be real number. The term "a" is called the "real part" and the term "b" is the imaginary part.
