Solve what is in the parenthesis first. Then multiply that by 2 then divide that by 3 then multiply that by 2. know your order of operations.

Please help<br>are these functions or not?​
crimeas [40]

Answer:

1. Function

2. Not a function

3. Function

4. Not a function

Step-by-step explanation:

A function just means that for each input it outputs only 1 output. This output isn't necessarily unique. So for example if you're just given: f(2) = 3 and f(1) = 3, this is a function since each input only outputs 1 value, even though the output isn't unique, but if you're given: f(3) = 2, f(2) = 1, f(3) = 3. that's not a function since f(3) outputs both 2 and 3.

Anyways now that you hopefully understand this, let's look at each image.


Relation 1: (Function)

   So for each input (the domain) it's only pointing to one output (range), even if multiple input (the domain) are pointing to the same output (the range), it's still a function.

Relation 2: (Not a function)

   This is not a function, since if you look at the input 7 (the range), you'll see it outputs two things (range). It outputs -6 and -7. So this is not a function

Relation 3: (Function)

   This is a function since each x-value (input) has only one y-value (output). So it's a function

Relation 4: (Not a functio)

   This is not a function, since there are multiply coordinates with the same x-coordinate (input) and different y-coordinates (output). The x-coordinate 2 has the output b, y, and m, and since no value is given for these variables, it can be assumed they're different values, thus it's not a function.

Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
quester [9]

Given:

Total amount of Mingfa and her sister = $130

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

To find:

How much money does Mingfa actually have?​

Solution:

Let, Mingfa have $x and her sister has $y initially. Then,

x+y=130                ...(i)

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

x+10=3y              ...(ii)

Substitute the value of x from (ii) in (i).

(3y-10)+y=130

4y=130+10

4y=140

Divide both sides by 4.

y=35

Putting y=35 in (i), we get

x+35=130

x=130-35

x=95

Therefore, Mingfa have $95.

For the sequence -28,-16,-4,8,... The expression that defines the nth term where a 1 =-28 is 12 - 28n 2 12 - 28(n - 1) 3. - 28 +
GrogVix [38]

Answer:

a₁ = -28

aₙ = a₁ + 12 (n-1)

Step-by-step explanation:

a₁ = -28

a₂ = -28 + 12 (2 - 1) = -16

a₃ = -28 + 12 (3 - 1) = -4

a₄ = -28 + 12 (4 - 1) = 8

aₙ = a₁ + 12 (n-1)

I dont remember how to solve these kinds of problems. can someone help me out?
jekas [21]

Answer:

w = 19

Step-by-step explanation:

to evaluate for the value of x in the expression 20 = w + 1 is very simple and direct, just look for a way to make w stand alone , that is look for a way to express w in terms 20 and 1

solution

20 = w + 1

collect the like terms

20 -1 = w

19 = w

w = 19

therefore the value of w in the expression 20 = w + 1  is evaluted to be  19
