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!
_red_ = _3_ (set up problem)
blue 8
blue=40 R=red (define terms)
_ R_ = _3_ (cross multiply)
40 8
8R=120 (divide by 8 on both sides)
R=15
The answer is B.15
If t is the amount of time she used it, then it lost t*(5/min) percentage points; then she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.
This means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.
This means that she used her phone for 10 minutes and charged it for 20 minutes.
If the ratio is 1:18, and we need to know how the other side for the ration 9:?, then we have to multiply 9x18.
9x18=162
so Laurel and Delmar are 162 km away
hope it helps! :3
Hello!
I don't exactly understand your question. If you mean to be asking whether or not 1002 is geater than 100, it is.
If you mean to be asking to add it: 102 + 900 + 100 = 1102
