Concept:
If every element of a set D is an element of set E, then D is the subset of E.
e.g
D={1,2,3}, E={1,2,3,4}
As all the elements of D are in E, so D is the subset of E.
Now the intersection of two sets D and E is the set of all elements which belong to both D and E.
As, in our example the set D={1,2,3} is the intersection of set D and set E.
From the above discussion, it is proved that <span>If set D is not the empty set but is a subset of set E then
</span> <span>D ∩ E = D is the true answer.</span>
Answer:
(0, -1)
Step-by-step explanation:
The c value of the equation represents the y-intercept. c=-1 so the y-intercept must be (0,-1)
Answer:
the second one
Step-by-step explanation:
Since an integer is a whole number, the numbers closer to 0 on the number line are -2 and -1, so there are 2 options.
The answer is 2 choices, in short.
Answer:
0.25 (inches?)
Step-by-step explanation:
the equation is:
y=mx+b
y is the length of her hair, the dependent variable, the outcome
m is the slope, which is in this case the growth of her hair in a month
x is the independent variable, or the number of months
b is how long her hair is to start with, which is 12 in
we are looking for m, which is the growth of her hair per month, which is given as 0.25 inches, so that would be the answer
