For ease of calculating, I'll assume the following: 1)  There is no space between the bricks. 2)  The 4 inch measure will be aligned with the 6 ft wide 3)  The 8 inch measure will be aligned with the 24 ft length. Step 1.  Find how many 4 inch bricks it takes to make 6 … Read more

Reference: Math.com The domain of a function is the set of all possible x values which will make the function "work" and will output real y-values. When finding the domain, remember: •The denominator (bottom) of a fraction cannot be zero •The values under a square root sign must be positive For this function if you … Read more

These series of questions appear to be dealing with straight line functions.  Therefore,  assume the equation is y - 1 = (5/6)(x -4). If the function is assumed to be y - 1 = 5/[6(x - 4)], the function would be a natural log function, which is much more difficult to develop. So y - … Read more

The because(6x) as x tends to 0 is 1.                       Substitute 1 for because(6x) term The 3x as x tends to 0 is 0.                               Substitute x for 3x term The term 1/x … Read more

This is a substitution problem.  Substitute the known value for "a" and "b" into the equation and solve: Thus, the equation becomes  3(4) + 3(2) = 12 + 6 = 18 or by the distributive law  3(4) + 3(2) = 3(4 + 2) = 3(6) = 18

Zero multiplied by any number is Zero.  Thus, there is no unique number that can be multiplied by Zero and result in obtaining 45. Multiplication is the process of adding a number a multiple number of times.  For example:  45 x 1 is to add 45 once.  Thus 45 x 1 = 45,  and 45 … Read more

When you divide by a fraction, you simply invert the fraction and then multiply.  So:  (4)/(1/4) = 4 x (4/1) = 4 x 4 = 16
