Please helpand please explain the answers to weather its linear or nonlinear?​

Answer:

this is a nonlinear function

Step-by-step explanation:

a linear function is when the y value increases the same amount every time the x value increases by 1(or any constant interval). in this problem when x increases 1, they y value increases by 2 for the first 3 sets of numbers, but in the 4th set of numbers the x value increases by 1 and the y value increases by 2. This does not follow the same pattern and therefore makes this nonlinear. A quicker way to figure this out when you have a graph like this is to draw a line through all the points in order of increasing x values or vice versa if the line you drew is straight all the way through then it is linear and if it isn't then it is nonlinear. I hope this helped.

I am not sure what the set/sets are supposed to be...
Fudgin [204]

Answer:

  see the attachment

Step-by-step explanation:

(a) S1 is the set of all subsets of {t, u, v}. There are 2^3 = 8 subsets, the EMPTY set being one of them. They are listed in the attachment.

It seems likely your answer will need to match that shown in the attachment:

  {EMPTY, {t}, {u}, ... , {t, u, v}}

where the elements of multi-element sets are listed separately: {t, u}, not {tu}.

__

(b) S2 is the set S1 with <em>w</em> added to each subset. (see the attachment for a listing)

__

(c) Correct, the sets are disjoint, since every set in S1 is different from every set in S2.

__

(d) Each set has 8 elements; the sets are the same size. You know this because you created set S2 from set S1. (See (b), above.)

__

(e) The sets are disjoint (see (c)), so the total number of elements in their union is the total of the numbers of elements in each set: 8 + 8 = 16.

__

(f) P(A) is undefined here, so none of these questions can be answered.

Amiraneli [1.4K]

Answer:

3 1/4

Step-by-step explanation:

3/4 + (1/3 ÷1/6) - (-1/2)

Subtracting a negative is adding

3/4 + (1/3 ÷1/6) +1/2

Parentheses first

Copy dot flip

3/4 + (1/3 * 6/1) +1/2

3/4 + 2 + 1/2

Get a common denominator

3/4 + 2 + 2/4

2 + 5/4

2 + 4/4 +1/4

2+1 + 1/4

3 1/4

Can someone help me with this plz? Plz show ur work .... A local high school collected $1590 from 321 people who attended a foot
madreJ [45]
To solve this problem we can use system of equations.
First equation can be
321=x+y 
where x - ppl between 4-17 and y - adult
second equation can be as follows
1590=6*y+4*x
So we have
\left \{ {{321=x+y} \atop {1590=6y+4x}} \right.
From first equation we get value of x in times of y
x=321-y
Now we can substitute it into second eq.
1590=6y+4(321-y) 
now simply if
1590=6y+1284-4y            /-1284 both sides
306=2y                /:2 divide both sides by 2
y=153 
Now we can back substitude
x=321-153
x=168
So we get result
\left \{ {{y=153 - adult} \atop {x=168 - kids}} \right.

Solve photo question, please.
Andru [333]
X>-2
any point to the right of x=-2 is a solution

y<u><</u>2x+7
to find, plot 2 points by subsitution
when x=0, y=7
when x=1, y=9
plot the points (0,7) and (1,9)

the point is (-1,4)

draw a line through them
then try a point to see which side to shade on
is 0,0 in that shaded reigon?
no
shade below

look at shaded reigon
