Answer:
y and x are variables, the 5 in 5y is a coefficient so is the 4 in 4x, the 3 is called a constant
Step-by-step explanation:
Answer:
So I'm not completely sure what the x is standing for in this. Is it standing at a multiplication sign like -14 TIMES 2? Or is it -14x TIMES 2?
Step-by-step explanation:
N=nickels
d=dimes
n+d = 30
n+18 = 30
n = 30-18
n = 12 (number of nickels)
therefore Mary has 12 nickels
Y=3x+3. Y-intercept= (0,3)
Answer:
no
Step-by-step explanation:
In a function, each "x" value [input] must have only one corresponding "y" value.
We know that points are written as (x, y)
Our points: {(3,-2), (1, 2), (-1,-4), (-1, 2)}
We can see that the x-input of -1 has two y-outputs, so this is therefore not a function
hope this helps! have a lovely day :)
