Answer:
14x-10y=-96
Step-by-step explanation:
we know that
The equation of the line in standard form is equal to
Ax+By=C
where
A is a positive integer
B and C are integers
so
we have
y=1.4x+9.6
Multiply by 10 both sides
10y=14x+96
isolate the variable x and y (Remember that A must be positive)
14x-10y=-96 -----> standard form
X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
Answe you ugly that the answer
Step-by-step explanation:
Answer: m = 2/3
Step-by-step explanation: Use the slope formula to find the slope m.
: m = slope :
: slope of a line : m = rise/run = y2-y1/x2-x1 :
: (x1,y1) : coordinates of first point in the line :
: (x2,y2) : coordinates of second point in the line :
