31
This is simple. The tens digit has to be two less than the ones.
The numbers that fit this rule are...
20 31 42 53
Then, they have to be in between 25 and 50.
The numbers that fit this rule are...
31 and 42
Then, i has to be prime
31 is the only one that fits all three
Answer:
1/2
Step-by-step explanation:
y2 - y1. over. x2 - x1
Answer:
See explanation below for all parts
Step-by-step explanation:
Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)
The answer for number 3 is y=2x+b.
For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).
-5=2(-4)+b Now simplify
-5=-8+b then add 8 to both sides to isolate b
3=b or b=3
For number 9, you now know that m is 2 and b is 3
y=2x+3
Answer:
You can solve this by having 2 different equations and setting both of them to 180 because they are supplemetnary anhles
Step-by-step explanation:
so for abc the equation= 180, then solve
then for the other angle cbd=180, then solve
