Answer:
y = 1/2x - 4
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = -2x + 8. Its slope is -2. A line perpendicular to this one will have a slope of 1/2.
Plug this value (1/2) into your standard point-slope equation of y = mx + b.
y = 1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -2). Plug in the x and y values into the x and y of the standard equation.
-2 = 1/2(4) + b
To find b, multiply the slope and the input of x (4)
-2 = 2 + b
Now, subtract 2 from both sides to isolate b.
-4 = b
Plug this into your standard equation.
y = 1/2x - 4
This equation is perpendicular to your given equation (y = -2x + 8) and contains point (4, -2)
Hope this helps!
Answer:
its probably is B. I am not sure. I wouldnt trust me though but you can if you want. ._.
1.5 is lesser than 0.5. Oh, wait nevermind I meant to say -1.5 is lesser than 0.5
Answer:
1920 ft^3
Step-by-step explanation:
Split it in 2.
14*8*10 and 10*10*8
14*10*8 = 1120
10*10*8 = 800
800 + 1120 = 1920
1st question
make line plot similar to the second. above 1/6 put 6 x's; above 1/3 put 3 x's; above 1/2 put 6 x's.
average: 1/3
