Answer:
Step-by-step explanation:
2x2+5x−10=x2+4
Step 1: Subtract x^2+4 from both sides.
2x2+5x−10−(x2+4)=x2+4−(x2+4)
x2+5x−14=0
For this equation: a=1, b=5, c=-14
1x2+5x+−14=0
Step 2: Use quadratic formula with a=1, b=5, c=-14.
x=
−b±√b2−4ac
2a
x=
−(5)±√(5)2−4(1)(−14)
2(1)
x=
−5±√81

x=2 or x=−7
Answer:
x=2 or x=−7
Answer:

Step-by-step explanation:
we know that
The volume of the cylinder is equal to

we have


substitute


Answer:
So, the slope is the number attached to the x.
In this case the slope is -2/5.
Example: y = 5x + 3
In this case, the slope is 5 because it is the number attached to the x.

A. Has the mean of 11
B has the mode of 7
We are given with a circle of center at (6,4) and that passes through (2,1). In this case, we follow the formula (x-h)^2 + (y-k)^2 = r^2.Substituting, (x-6)^2 + (y-4)^2 = r^2. at (2,1), we substitute the points: r then is equal to 5 which is the radius of the circle. The final equation of the circle is then (x-6)^2 + (y-4)^2 = 25.
