Answer:
is equivalent to the inequality 
Step-by-step explanation:
Given inequality : 
We are supposed to find Which of the following is equivalent to the inequality


Multiply both sides by 10


is equivalent to the inequality 
So, Option B is true
B) 
1 is not a function. 2 is not. 3 is not. 4 and 5 are functions. 6 is not.
angle BCA would be 60, so 50 + 60 = 110, so angle CAB would be 70
we can do this by 2 ways
1- by plotting the points on graph and then tracing the points to get shape,
for linear, we will get straight line
for quadratic, we will get parabola
in this case, it is linear as we get a straight line
2- by solving for values of x and y
consider standard linear equation y = mx +c where m is slope and c is constant
by putting given values of x and y we get
y + 2x = 4(answer)
if we consider standard parabola equation
y^2 = 4ax
this equation is not true for given points
