If b is between a and c then ab+bc=ac

That's false. Take the numbers 1, 3, and 5.
Let a = 1, b = 3, and c = 5.
ab + bc = ac
3 + 15 = 5
18 ≠ 5
Since 18 does not equal 5, this is false. If you were to use the distributive property on ab + bc = ac, you would get
b(a+c) = ac, which doesn't even make sense.
Have a nice day! :)

How far above ground is the flag pole in inches? Round to nearest inch if needed
VikaD [51]

Answer:

Step-by-step explanation:

You'll use similar triangles to solve this. Set up 2 ratios as a proportion. First, however, you have to convert the 15 inches to feet. If everything else is in feet, then EVERYTHING has to be in feet. 15 inches is equal to 1.25 feet. Now for the equation:

\frac{3}{x} =\frac{1.25}{6}

The first fraction is made up of the heights, 3 being the height of the plumb bob and x being our unknown height of the flagpole; the second fraction is made up of the distances on the ground. Cross multiply to solve:

1.25x = 18 so

x = 14.4 feet, or 14 feet, 4.8 inches

Solve each equation for y. 3x + 2 =6y
Strike441 [17]

Answer:

1/2x + 1/3 = y

Step-by-step explanation:

3x + 2 =6y

Divide each side by 6

3x/6 + 2/6 = 6y/6

Simplify

1/2x + 1/3 = y

Write an equation in slop _intercept form of the line that bisects the angle formed by BA and BC
kotegsom [21]

Answer:

y = -x + 2

Step-by-step explanation:

Angle between these lines = 90°

Angle between BC and the angle bisector BD = 45°

Since, m(∠DBE) = 90° + 45° = 135°

Therefore, slope of the angle bisector BD = tan(90° + 45°)

                                                                      = -tan(45)°

                                                                      = -1

Let the equation of the angle bisector which passes through (x', y') and slope = m,

y - y' = m(x - x')

Where m = slope of the line = (-1)

Since, the angle bisector passes through a point B(-1, 3),

Equation of BD will be,

y - 3 = (-1)(x + 1)

y - 3 = -x - 1

y = -x - 1 + 3

y = -x + 2

Solve (D*D + 4)y = x + cos²x​
Sedaia [141]

Answer:

(D^2 + 9)y = cos 2x….(1). The corresponding homogeneous equation is (D^2 +9)y= 0,…(2), whose auxiliary equation is m^2 + 9 = 0, which has (+/-)3i as roots. The general solution of (2) is y = A.cos(3x) + B.sin(3x). Now to get a general solution of (1) we have just to add to the above, a particular solution of (1). One such solution is [cos(2x)]/[-2^2 +9] = (1/5).cos 2x. Hence a general solution of the given equation is given by y = A.cos(3x) + B.sin(3x) + (1/5)cos(2x), where A and B are arbitrary constants. The above solution incorporates all the solutions of the given equation.

6x2 - 21 = 33; Solve and what are the x-intercepts of this quadratic equation ?
lara31 [8.8K]
Solving by factoring.
6x^2 - 21 - 33 = 0
6x^2 - 55 = 0
x^2 - 9 = 0
(x-3)(x+3) = 0
x - 3 = 0
x + 3 = 0
x1 = -3
x2 = 3
