"What percent" is our unknown x, "of" means we will multiply, "is" means equals. We set up the equation accordingly: x(12.5) = 39. 12.5x = 39. Divide both sides by 12.5 to get x = 3.12. To get to the percent form we multiply by 100 to get 312%.
Answer:
Step-by-step explanation:
Answer:
B = (-6, 6)
Step-by-step explanation:
If M is the midpoint of AB, then ...
B = 2M - A
B = 2(-1, 4) -(4, 2) = (-2-4, 8-2)
B = (-6, 6)

Step-by-step explanation:
----------------------------------------------
Find Slope :
----------------------------------------------
y = 3x + 4
Slope = 3
----------------------------------------------
Form equation :
----------------------------------------------
y = 3x + b
----------------------------------------------
Find y-intercept :
----------------------------------------------
At (1, 2)
2 = 3(1) + b
2 = 3 + b
b = -1
----------------------------------------------
Form equation :
----------------------------------------------
y = 3x -1
----------------------------------------------
Answer: y = 3x - 1
