Answer:
x + y = - 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - x - 5 ( add x to both sides )
x + y = - 5 ← in standard form
Answer:
x≥3
Step-by-step explanation:
Treat the ≥ symbol like it is an equals sign. First, subtract 14x from each side to get 6x+12≥30. Then, Subtract 12 from each side to get 6x≥18. I will let you solve the rest :)
Answer:
Step-by-step explanation:
The intersection of the parabola with the x-axis is the solution of this equation. Accordingly, if the parabola does not intersect with the x-axis, there will be no solutions
Answer: C
Answer:
11/25 The right answer is not a part of the options given.
Step-by-step explanation:
Given;
Probability that event M will not occur = 0.8
Probability that event R will not occur = 0.6
Then the ;
Probability that event M will occur = 1 - 0.8 = 0.2
Probability that event R will occur = 1 - 0.6 = 0.4
If events M and R cannot both occur, probability that either event M or event R will occur
= probability that M occurs and R does not or the probability that R occurs and M does not
= 0.2 × 0.6 + 0.4 × 0.8
= 0.12 + 0.32
= 0.44
= 11/25
