Answer:
B. y=1/2x+7
Step-by-step explanation:
y2-y1/x2-x1 this finds the slope
Then take one of the coordinates: either (2,8) or (4,9) and plug them into x and y to find b (the y-int)
The answer to this question is C, I can explain it if you would like.
Answer:
x= 85 is the answer. ( because exterior angle of a triangle is equal to 2 non adjacent interior angle of a triangle..)
The known facts
- the sum of Natalie's age and Fred's age is 36
- the sum of Fred's age times four and Natalie's age is 72
Now, let's set up the equations where N is Natalie's age and F is Fred's age.
N + F = 36 ---- equation 1
N + 4F = 72 ---- equation 2
equation 2 minus equation 1 ---> 3F = 36 ---> F = 12, thus N = 24
Thus Fred is 12 years old, and Natalie is 24 years old.
