8^2y+4 = 16^y+1

Answers

Answer:

y = -4

Step-by-step explanation:

Assuming the problem is $8^(2y+4)=16^(y+1)$ , it would be nice if we could convert both sides of this equation to the same base; that way, we could compare the exponents directly in an equation of their own. Fortunately, 8 and 16 are both powers of 2 -- $2^3$ and $2^4$ , we can rewrite the original equation by substituting those in:

$(2^3)^(2y+4)=(2^4)^(y+1)$

When you have an exponent raised to another exponent, you multiply those exponents together, so we can simplify our equation by distributing a 3 in the left exponent and a 4 in the right:

$2^(3\cdot(2y+4))=2^(4\cdot(y+1))\n2^(3\cdot2y+3\cdot4)=2^(4\cdot y+4\cdot1)\n2^(6y+12)=2^(4y+4)$

With both of our bases the same, we can now simply compare their exponents directly to solve for y:

$6y+12=4y+4\n2y=-8\ny=-4$

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x------> the number of minutes

y------> the depth in feet

In this problem the relationship between the variables, x, and y, represent a proportional variation

Remember that

A proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

step 1

Find the value of k

Let

$A(2,3)$ ------> see the given table

$k=y/x$ ----> substitute the values

$k=3/2=1.5$

The direct variation equation is equal to

$y=1.5x$

step 2

Complete the table

For $x=3\ min$

substitute the value of x in the equation and solve for y

$y=1.5(3)=4.5\ ft$

step 3

Complete the table

For $y=6\ ft$

substitute the value of y in the equation and solve for x

$6=1.5x$

$x=6/1.5=4\ min$
