Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Variation: Inverse proportional.
This is represented as:
See attachment for table
Solving (a):
First convert variation to equation
From the table:
So, we have:
Substitute 4 for k in
Solving (b): x when y = 25.
Substitute 25 for y in
Cross Multiply
Divide through by 25
Take positive square roots of both sides
Answer:
yes, its linear and proportional .
Step-by-step explanation:
In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant, that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.
you just have to graph it .
hope i helped :) !!! brainliest ??
Answer:
answer = c
Step-by-step explanation:
its because we need to add 1 more 4 for the number 4 to be the mode because the mode is the most nummber used
Tienes que usar la fórmula cuadrática:
(-b +/- √(b^2-4ac))/2a
Primero identificas los valores de a,b y c en kx^2-3x+2=0
K=a, b=-3, c=2
Luego sustituis en la fórmula y te queda:
(3+/-√(9-8k))/2k
Para que las raíces Sena reales se tienen que cumplir que 9-8k>=0
