Make x the subject of the formula
y/x= abc
Answer:
x=y/abc
Step-by-step explanation:
Let's solve for x.
y/x=abc
Step 1: Multiply both sides by x.
y=abcx
Step 2: Flip the equation.
abcx=y
Step 3: Divide both sides by abc.
abcx/abc=y/abc
x=y/abc
Answer:
x=y/abc
Step-by-step explanation:
In order to make x the subject:
Isolate the variable by: ...
Rearrange the equation so each term containing x is on the same side of the =.
Factorisation may be needed if there are multiple terms containing x . ...
Perform an operation to ensure only a single x variable is left as the subject.
What do I do? I'm confused
Answer:multiply each side by 2.5

Susan is taking an Algebra test on functions. Question 10 shows the following list of ordered pairs:
{(–5, 7), (–2, 1), (0, 3), (4, 7)}
Which choice should best explain why the relation IS or IS NOT a function?
Question 2 options:
a function; only one range value exists for each domain value
a function; two domain values exist for range value 7
not a function; the relation does not pass the horizontal line test when all points are graphed
not a function, two domain values exist for range value 7
Answer: 1. a function; only one rage value exists for each domain value
2. (-5, 7) , ( -2 ,1) In mathematics, a function is a relation that associates each element of a set (the domain) with a single element of another .In this case 2 elements are smaller than 0 and 2 are bigger than 0

Susan has 7 chores, and she can do them in any order. Use the fundamental counting principle to find the number of different ways she can complete her chores.
EXPLAIN
Explanation:
There are 7 choices for the first slot, then 6 for the second, 5 for the third, and so on until we get down to 1 choice for the last slot
7*6*5*4*3*2*1 = 5040 different ways to do those seven chores where order matters.

PLS HELP EXAM
a) -2 = y + 5
c) –2x + 3x – 5 = 6 – 21
e) 4 – 14 = 5x
g) –42 + 20 = –2x + 13x
i) 7 = y – 2
k) –4 – 10 = 4y + 3y
m) 3y = –18
Answer:
a: y = - 7
c: x = -10
e: x = 2
g: x = -2
i: y = 9
k: y = -2
m: y = -6
Step-by-step explanation:
a: Subtract 5 on both sides
c: Add 5 on both sides then combine like terms
e: Combine like terms then divide by 5
g: Combine like terms then divide by 11
i: Add 2 on both sides
k: Combine like terms then divide by 7
m: Divide by three(won't add the number for some reason)
