Answer:
k = 8
Step-by-step explanation:
A slope of 3 means that y increases by 3 when x increases by 1.
The second point (2, k) has an x-value (2) that is 1 more than the x-value (1) of the first point (1, 5). This means the y-value (k) of the second point (2, k) will be 3 more than the y-value (5) of the first point (1, 5).
k = 5 + 3 = 8
4 x 12 is 48 and then plus 20 is 68
ANswer to 1 is 68.

Answer:
Step-by-step explanation:
Given

Required
Determine the type of roots
Represent Discriminant with D; such that

D is calculated as thus

And it has the following sequence of results
When
then the roots of the quadratic equation are real but not equal
When
then the roots of the quadratic equation are real and equal
When
then the roots of the quadratic equation are complex or imaginary
Given that
; This means that
and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
5 1/4 - 3 3/4 = 4 5/4 - 3 3/4 = 1 2/4
Answer:
All of them are right
Step-by-step explanation:
Are you sure the question was that?
Collinear means that it lies on the same line
Now, from every 2 points passes a unique line
So(0,0) and (3,2) are in a line
(0,0) and (1,0) are in an other line and so on
