Hello from MrBillDoesMath!
Answer: x^2 - 6.5x + 10.5 = 0
Discussion:
If the roots are 3 and 3.5, then the quadratic equation is
(x -3 ) ( x - 3.5) = 0
or
x * (x - 3.5) - 3 (x - 3.5) = 0
or
X^2 - 3.5X - 3X + 3(3.5) = 0
or
x^2 - 6.5x + 10.5 = 0
Thank you,
MrB
Answer:
the forth one is linear
Step-by-step explanation:
Answer:
Step-by-step explanation:
You need to get w on one side by itself.
Start out by subtracting 2l from both sides.
p−2l=2w.
Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.
w=p2−I
Answer:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".
