Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ± )/2a
= (-3± )/2*1
= (-3±)/2
= (-3±√21)/2
Answer:
The difference in slopes of is = 3
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is = -7
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
Step-by-step explanation:
Given equation:
We need to find the difference of slopes and y-intercepts of the given equations.
The standard form of a slope intercept equation of line is given by:
where represents slope and
represents y-intercept of line.
Writing the given equations in standard form to find slope and y-intercept.
Slope = 2 and y-intercept =-2
Slope = -1 and y-intercept =5
The difference in slopes of is =
We can say slope of is positive and 3 more than slope of
while slope of
is negative.
Difference of y-intercepts of is =
We can say the y-intercept of is positive and 7 units above
while y-intercept of
is negative.
Answer:
Subsets of the given set = 32
Proper subset of the given set = 31
Step-by-step explanation:
Given set is {18, 8, 14, 9, 6} having 5 elements.
We know number of subsets of a set having n elements are represented by
where n is the number of elements in the set.
Therefore, subsets of the given set =
= 32
Since original set itself is a subset of its own, is not a proper subset.
Therefore, proper subset of a set =
=
= 32 - 1
= 31
