Both of them add up to 34!
I hope this helps.
Have a "AWESOME" day! :)
Answer:
-1
Step-by-step explanation:
There are things called domain and range.
Domain is all the x values and range is all the y values.
Since in your picture the parabola only seems to be touching -1, that is your domain.
Answer:
the real size, 20 km, by
2.5
/1 Then, 20 x 2.5=50. So the answer is 50 km
Step-by-step explanation:
Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.
I believe this is the solution.
Use the distance formula: D=sqrt((x2-x1)^2+(y2-y1)^2)
Plug in:
D=sqrt((9-8)^2+(-1-2)^2)
D=sqrt(1^2+(-3)^2)
D=sqrt(1+9)
D=sqrt(10)
So the distance is about 3.16 units
Hope this helped!
