In a mapping diagram how many ordered pairs are there for every row?
The answer is 1
Hunter is going to graph the ordered pairs that are represented by this table on a coordinate plane.?
1
Which equation represents a direct linear variation?
Y=1/x
Can the roots of a quadratic be listed as ordered pairs?
In the case of real roots, you could, but the second part of the ordered pair (the ordinate) will always be zero, so there is not much point.In the case of complex roots (or real roots in the complex field), you could list them as ordered pairs: with (a, b) representing a + bi where i is the imaginary square root of -1..
What is a direct variation?
A direct variation is when the value of K in multiple proportions is all divisible by the same number for example: XY=(1)(10) K=10 XY=(2)(20) K=40 XY=(3)(30) K=90 XY=(4)(40) K=160 In this situation the constant (K) of each proportion is divisible by 10 making the multiple equations a direct variation.
Are these ordered pairs in direct variation -1 0 3 2 9 6?
No. For direct variation, any order pair with a 0 in it MUST be (0,0).
What is -1 in ordered pairs?
-1 is a one-dimensional entity. It can have no equivalent in ordered pairs.
How do you solve the direct variation y equals 5x plus 1?
y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.
How do you do a direct variation with an inverse variation problem?
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
Is the problem y equals 3x a direct variation if so what is the constant of variation?
y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
What is the constant of variation in the direct variation x-y equals 0?
1
Is y9x 1 a direct variation function?
No.
Can ax plus by equals c be a direct variation if a and b and c does not equal 0?
No, direct variation is "y=ax." In direct variation a equals any real constant, b=1, and c must equal zero. If any of thee conditions are changed, it is not direct variation.
Which of these equations is a direct variation y equals -8x plus 1?
There is only one equation that is given in the question and that equation is not a direct variation.
In a mapping diagram how many ordered pairs are there for every row?
The answer is 1
In a mapping diagram how many ordered pairs are there for every arrow?
1
How do you find how many pairs are there in any given group of numbers?
If there are n numbers in the group, there aren2 ordered pairs if the numbers can be repeated,n*(n-1) ordered pairs if the numbers cannot be repeated,n2/2 pairs if the numbers can be repeated,n*(n-1)/2 pairs if the numbers cannot be repeated.
