M=(755-800) /30-12
m= -45/18 or -2.5
y-800 = -2.5(x-12)
y-800 = -2.5x + 30
y = -2.5x + 830
y = -2.5(120) + 830
y = 530 lbs
Answer:
x=1
y=2
Explanation:
first start with assigning a random value to a variable
lets say x=1
from there the equation becomes solveable
-6x1+7y=8
simplify
-6+7y=8
+6 to both sides
7y=14
divide both sides by 7
y=2
from here we can say that x=1, y=2, can satisfy the equation-6x+7y=8
hope this helps :)
Answer:
3/14
Step-by-step explanation:
You basically flip the numbers around. Hope this helps!
Using a graphing calculator, we can see the graph of the function y = x²-4x+1:
as we can see, the vertex of the function is (2,-3), and the solutions are (0.3,0) and (3.7,0)
