13 is a prime number because you can't multiply 2 numbers to make 13
Point slope or standard form? Standard is y=0-+1, point is y=1
Answer:
The coefficients are 4 and 2
Step-by-step explanation:
they are the ones in front of the variables
for example, the coefficient of 12x is 12

I think its C sorry if its wrong
What do the two variables represent?
The two variables represent the number of nights or squires at the jousting contest.
Write a system of equations.
let k = number of knights and let s = number of squires
3k + 2s = 32
2k + s = 19
How many knights are there? <u>6</u>
How many squires are there? <u>7</u>
Solving:
solve for s in the second equation by subtracting 2k from both sides
2k + s = 19
s = 19 - 2k
substitute into first equation
3k + 2(19-2k) = 32
distribute 2 into 19-2k
3k + 38 - 4k = 32
add like terms
-k + 38 = 32
subtract 38 from both sides
-k = -6
divide by -1
k = 6
subsitute into the equation for s
s = 19 - 2k
s = 19 - 2(6)
s = 19 - 12
s = 7
