Answer:
b < -10 and (-∞, -10)
Step-by-step explanation:
I won't draw the number line but I will do the interval notation.
Interval notation is a way to describe infinite or finite sets with numbers.
To solve the inequality first add 2 to both sides to get:
-b > 10 Multiply both sides by -1:
b < -10 is the simplification of the inequality .
Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).
Interval notation: (-∞, -10)
Answer:
f(x)= -3x+10
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Plug in (-1 , -2) in the LHS of the equation.
2x - 3y = 2*(-1) - 3*(-2)
= -2 + 6
= 4 = RHS
So, (-1 , -2) is a solution
Answer:
Domain : {3, 1, 2, 4, 6, 5}
Step-by-step explanation:
Domain of a function is always defined by the input values (x-values).
Similarly range of any function is defined by the output values (y-values).
From the table given in this question,
Units given in the table will define the domain of the data.
Therefore, domain will be the set of numbers {3, 1, 2, 4, 6, 5}.
