Answer:
21/10 or 2.1
Step-by-step explanation:
Answer:
The answer is 3 units apart.
Step-by-step explanation:
The points are (1,9) and (4,9). The y-coordinates are the same. The x-coordinates are different. To find the difference between them, you must subtract them. 4-1=3, so the points are 3 units apart!
Answer:
The Statement D⊆B is False.
Step-by-step explanation:
Given:
A = {1, 3, 5, 7 }
B = {5, 6, 7, 8}
C = {5, 8}
D = {2, 5, 8}
U = {1, 2, 3, 4, 5, 6, 7, 8}
To Check:
D⊆B = True or False
Solution:
The sign '⊆' symbolize SUBSET
So D⊆B means D is the Sub Set of B
That means All the element of Set D must be there in the SET of B Then it comes True.
Or else it is False
D = {2, 5, 8}
B = {5, 6, 7, 8}
Therefore D⊆B is a FALSE statement
For it to be TRUE we must have set B as
D = {2, 5, 8}
B = {2,5, 6, 7, 8}
Now D⊆B is a TRUE statement
Answer:
Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6
Step-by-step explanation:
1. -5(2-5n)+6=-5n-34-2
Distributive Property
-10+25n+6=-5n-32-2
Add Like Terms
-4+25n=-5n-34
Subtract -4
25n=-5n-30
Subtract -5n
30n=-30
Divide by 30
n=-1
2. -5(2-5n)+6=-5n-34-20
Distributive Property
-10+25n+6=-5n-32-20
Add Like Terms
-4+25n=-5n-52
Subtract -4
25n=-5n-48
Subtract -5n
30n=-48
Divide by 30
n=-1.6
Answer:
-7y > 161
7y < -161
y < -23
7y > -161
y > -23
So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.
