Answer:
y = -5x + 8
Step-by-step explanation:
Equation of a line: y = mx + b
x = slope
b = y-intercept or starting point
Slope = y^2 - y^2/x^2 - x^1
Slope = -12 - 43/4 - (-7)
Slope = -55/11
Slope = -5
b = y - y^1 = m(x - x^1)
b = y - 43 = -5(x - (-7))
b = y - 43 = -5x - 35
Add 43 to both sides
y = -5x + 8
C. If you have to add on a number it is nonproportional
Answer:
Step-by-step explanation:
Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in
), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.
1. 6 + p
Being p be a variable this equation is polynomial
2. x – 1
Since x-1 has variable and constant so according to definition it is a polynomial
3. 8x−z3
According to definition it is a polynomial
4 .
Since has root so it is not a polynomial .
Answer:
BD = 16
Step-by-step explanation:
32/BD = BD/8
BD² = 256
BD = 16
