Move a2 to the left side of the equation so you have c2-a2. then divide by 2 to get b by itself. you are left with c2-a2 all over 2. the 2s will cancel and you'll be left with c-a=b
Answer:
y=
x
Step-by-step explanation:
Given the two points:
- Origin (x1, y1) = (0, 0)
- The point (x2, y2) = (5, 9)
Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).
=>Time, x the independent variable,and distance is the dependent variable.
We have the standard form of a linear equation is:
y= mx + b where a is the slope
We know that, the slope of the function is:
m =
In this situatuon, m =
=> y=
x + b(1)
The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:
0 =
*0 + b
<=> b = 0
So our equation that the graph represents is: y=
x
3 periods....20 minutes each.....3 * 20 = 60 total minutes playing time
colin plays 12 minutes each period...12 * 3 = 36 minutes
Collins playing time to total playing time = 36/60 reduces to 9/15 or 9:15 or 9 to 15 <===
Answer:
0.65
Step-by-step explanation:
13 divided by 20 equals 0.65.
4x + 7x - 10x - 10 + 14 + 2
x + 6 is the simplified version of the equation.
