Answer:

B = j + H

Step-by-step explanation:

Given:

j = - H + B

Solve the equation for B

j = - H + B

Add H to both sides of the equation

j + H = - H + B + H

j + H = B

B = j + H

Find the perimeter of the rectangle whose adjacent sides are 3x-5y-4z and x-3y+5z
Kazeer [188]
<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ I'm assuming the answer is to be left in algebraic form.

Perimeter = length + length + width + width or (2 x length) + (2 x width)

Substitute the values in:

Perimeter = 2(3x - 5y - 4z) + 2(x - 3y + 5z)

Simplify:

Perimeter = 6x - 10y - 8z + 2x - 6y + 10z

Perimeter = 8x - 16y + 2z <== this is the answer

Mkey [24]

Answer:

(C) f’(c) = 0 and f”(c) > 0

Step-by-step explanation:

A minimum occurs where the first derivative is 0 (the tangent line is horizontal), and the second derivative is positive (concave up).  The simplest example of this is a positive parabola, like y = x², which has a relative minimum at its vertex.

What is the slope of the line equation 7x-3y=21
kramer
Equation: 7x - 3y = 21

3y = 7x - 21

Divide both sides by 3, 

y = 7/3x - 7

Compare it with principle equation, y = mx + c

Here, slope (m) = 7/3

In short, Your Answer would be: 7/3

Hope this helps!
