Answer:
B
Step-by-step explanation:
y-intercept is positive 5 so that eliminates answer choices A and C
to decide between B and D, select a point in the solution area; for example, (0, 0). Plug these values into B and D and see which one it is true for
B) 0 ≥ -3(0)-5
Is 0 ≥ -5 Yes
D) 0 ≤ -3(0)-5
Is 0 ≤ -5 No
Answer:
4
Step-by-step explanation:
A false statement implies a true statement,so the conditional statement is false.
Answer:
−7.6n+9.7
Step-by-step explanation:
First, lets put the equation
≈3.7 - 4.6n - 3n + 6
Add light terms
−7.6n + 9.7
Now were done
Yes. Easiest way too find it is plug them into your calculator, both solutions are .55555556. But if you don't have a calculator you can try to make the bottom numbers the same by seeing what they have in common...9. So 45/5=9 and 27/3=9. Then do the same to the top 25/5=5 and 15/3=5. Now we have 5/9 and 5/9 which are the same so they have the same proportions
Answer:
a) b) (a,b) (c, d) As long as (a,b) and (c,d) are the endpoints of of the diameter.
Step-by-step explanation:
a)
1) The reduced formula of the Circumference is given by:
2) Let's expand the factored one into one closer to the pattern above:
3) Completing the square for both trinomials:
4) In the Reduced Formula, ,
b) Using the previous example to show this:
When we factor this way
We are indeed, naming "a" and "b", the coordinates of (a, b) of the first endpoint and "b" and "d" the second endpoint as well.Id est, D (2, 5) and B (6,-11).
The radius, is
So yes, the equation of the circle can be written as
As long as (a,b) and (c,d) are the endpoints of of the diameter.
