What is a coefficient?

Mathematics
1 answer:
kakasveta [241]3 years ago
4 0
"A number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.
Example: x is really 1x.

<span>Sometimes a letter stands in for the number. </span>
Example: In ax2<span> + bx + c, "x" is a variable, and "a" and "b" are coefficients."

hope this helps you!

Someone please help!! find the value of y in this triangle
Ksenya-84 [330]

Answer:

30

Step-by-step explanation:

Triangle containing 120° and y° is an isosceles triangle.

Therefore,

y° + 120° + y° = 180°

2y° = 180° - 120°

2y° = 60°

y° = 60°/2

y ° = 30°

y = 30

How to write a domain
Gre4nikov [31]
The domain are all valid values for x (the independent variable) that can be used in an equation.

We have to look at any potential values of x which won't work. Easily put: in algebra, just look for values of x which cause either division by zero, or the square root of negative numbers.

A couple of examples: 
y=2x+4
You can insert any negative or positive value, or zero, for x and get a valid equation. Therefore the domain is the set of all real numbers. Answers are usually written as:
x: {R}, or simply 'all real numbers'.

what about y=2/(x-1)
In this equation, x appears in the denominator. If x-1=0, then division by zero would occur. 
Solve: x-1≠0
x≠1
In set notation:
x: (-∞,1)∪(1,∞)
Parentheses are next to the 1, as the domain comes up to 1, but does not include 1. 
Read left to right, the domain is "negative infinity to 1, exclusive, in union with 1 to positive infinity"
