Answer:
y = 2/3x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 2/3x + 1. Its slope is 2/3. A line parallel to this one will also have a slope of 2/3.
Plug this value (2/3) into your standard point-slope equation of y = mx + b.
y = 2/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (3, 0). Plug in the x and y values into the x and y of the standard equation.
0 = 2/3(3) + b
To find b, multiply the slope and the input of x (3)
0 = 2 + b
Now, subtract 2 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 2/3x - 2
This equation is parallel to your given equation (y = 2/3x + 1) and contains point (3, 0)
Hope this helps!
20*3/4 = 60/4....and 60/4 = 15
Answer:
60 = n
Step-by-step explanation:
This problem can be rewritten as:
18 is 30% of what?
% means "out of 100" and of means "multiply"
18 = 30/100 ⋅ n
100/30 ⋅ 18 = 100/30 ⋅30/100 ⋅ n
1800/30 = 100/30 ⋅ 30/100 ⋅ n (both the 30/100 and 100/30 are crossed out here)
60 = n
